Ready-made work kits for leather: cleaning and care graded by the leather's condition, refreshing colour with Leather Fresh, gluing and filling cracks. Plus special cases like convertible soft tops, washable leather items and sneakers. The right tools come in every box.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003e\u003cstrong\u003eSets from COLOURLOCK\u003c\/strong\u003e are pre-assembled work kits from the leather specialist that has come out of leather repair since 1995 and now belongs to Koch-Chemie. Each set puts cleaner, active product and tools together in the order they're actually used one after the other in detailing. Three families cover the need: cleaning and care sets by leather condition, colour kits for refreshing and re-dyeing, and repair kits for cracks and worn spots.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe combination decides, not the single product.\u003c\/strong\u003e Leather is acid-tanned and sits at pH 4.5 to 5.5. The mild cleaners in the sets are buffered to that window; alkaline all-purpose cleaners above pH 8 make the fibres swell and turn brittle. In a set, the pairing of cleaner and active product is matched at the factory – you don't have to work that out yourself.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraded by condition, not by model year.\u003c\/strong\u003e The care sets split at about three years: before that it's about protecting the intact top coat, after that about substance and UV protection, and for a classic car about rehydrating with softener and leather grease. The difference lies in how they work, not in the bottle size.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe tools are in the box, not next to it.\u003c\/strong\u003e Depending on the job, that's six to fourteen parts in one box: cleaning sponge, applicator sponge, leather brush, viscose cloths, nitrile gloves – and in the glue kit, sub-patch fabric and two mini brushes as well. No extra trip to an upholstery supplier, no improvised kitchen sponge on the seat bolster.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDetailing1's tip from the shop:\u003c\/strong\u003e Almost all the questions we get about the colour kits are about colour – which shade fits, where's the colour chart, will black do. But the mistake is usually in the order, not the shade. Apply the tint to a hidden spot first, such as the back of the backrest or under the seat base, and let it dry completely. Every leather colour looks darker wet than dry, and that exact difference makes people doubt themselves halfway through the job. With most manufacturers, the factory shade is listed as a colour name in the equipment data sheet for the VIN, not as a code on the B-pillar.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eA set is a workflow, not a bargain bundle\u003c\/h3\u003e\n\u003cp\u003eA COLOURLOCK set doesn't bundle leftover stock – it bundles the order a detailer works in: clean, let it work, wipe off, protect. The box is the instructions.\u003c\/p\u003e\n\n\u003cp\u003eThere's a chemical reason for that order. A care product or tint only bonds to a surface that's genuinely free of skin oils, sun cream and denim transfer – on a film of dirt it just sits on top and turns into a dust trap. Conversely, a cleaner that's too harsh pulls plasticisers out of the pigment layer, and no product gives them back afterwards. That's why, in a set, strength and follow-up treatment are calculated as a pair.\u003c\/p\u003e\n\n\u003cp\u003eThe tools in the box are part of that calculation. The foam dispenser delivers dense micro-foam instead of free liquid, so the cleaning stays on the surface and doesn't soak into the collagen fibre structure – soaked leather dries hard. The brush lifts dirt mechanically out of the grain without removing pigment, and the soft viscose cloths wipe off without leaving micro-scratches. Tools and chemistry are a unit here.\u003c\/p\u003e\n\n\u003cp\u003eThat COLOURLOCK in particular thinks this way comes down to its roots: the brand was born in 1995 at the Lederzentrum, has been supplying upholsterers and detailers for three decades and has belonged to Koch-Chemie in Unna since the end of 2023. If you repair damage, you know what causes it – and you put sets together from products that follow each other in the repair chain anyway.\u003c\/p\u003e\n\n\u003cp\u003eWe see that confirmed in our inbox every day: most set questions aren't about chemistry but about order and which product does what. Anyone who cared for the leather first and cleaned it afterwards gets in touch later because the leather has gone blotchy. A set heads off exactly that question.\u003c\/p\u003e\n\n\u003ch3\u003eThree set families for three different starting points\u003c\/h3\u003e\n\u003cp\u003eWhich set you need isn't decided by your leather type but by its starting condition: intact and just well-used, faded and washed out, or mechanically damaged.\u003c\/p\u003e\n\n\u003cp\u003eIf the top coat is fine, the \u003ca href=\"\/collections\/koch-chemie-colourlock-lederpflegesets\"\u003eCleaning \u0026amp; care sets from COLOURLOCK\u003c\/a\u003e are the go-to. They combine a mild leather cleaner with the active product that suits the condition – sealant, care milk or oil. The three classic interior sets are also grouped together as their own selection under \u003ca href=\"\/collections\/koch-chemie-colourlock-sets-lederalter\"\u003eLeather-age care kits by COLOURLOCK\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003cp\u003eIf the colour has worn thin on the entry edge, bolster or steering wheel rim, the \u003ca href=\"\/collections\/koch-chemie-colourlock-sets-farbsets\"\u003eColour kits by COLOURLOCK\u003c\/a\u003e take over. For spot refreshing, the \u003ca href=\"\/collections\/koch-chemie-colourlock-sets-leather-fresh\"\u003eLeather Fresh kits by COLOURLOCK\u003c\/a\u003e range from steering wheel size to pro containers; when a whole area needs rebuilding, the \u003ca href=\"\/collections\/koch-chemie-colourlock-sets-faerbe-sets\"\u003eComplete dye kits by COLOURLOCK\u003c\/a\u003e bring cleaner, colour, cross-linker and sealant together as one closed chain.\u003c\/p\u003e\n\n\u003cp\u003eWorth knowing, because many people expect a spray can of paint here: a refreshing tint is only a small part colour pigment; the large remainder is elastic binders and top coat. That's why it soaks into worn spots and fine scratches and cross-links with the remaining original colour, instead of drowning the grain under a layer. You'll notice: the treated bolster feels like leather afterwards, not like plastic film.\u003c\/p\u003e\n\n\u003cp\u003eIf substance is missing – a crack, a cut, a worn-through seam – the work starts with the \u003ca href=\"\/collections\/koch-chemie-colourlock-sets-reparatursets\"\u003eRepair kits by COLOURLOCK\u003c\/a\u003e. They include material no care product replaces: tear-resistant sub-patch fabric for backing, leather glue, filler, brushes. This family also includes the COLOURLOCK \"Leather Steering Wheel\" Set for the most heavily used spot in the car, the steering wheel rim.\u003c\/p\u003e\n\n\u003cp\u003eThe same routine runs across all three families: clean, degrease as well for repairs and dyeing, then build up substance, then colour, and protection right at the end. The degreasing step is the one almost everyone skips. The rule of thumb from detailing: keep wiping with the degreaser until the cloth shows slight colour traces from the original leather – then the skin oils really are gone. After every dyeing job, leave the area for a day before care or sealant goes on.\u003c\/p\u003e\n\n\u003ch3\u003eCondition decides the set, not the model year\u003c\/h3\u003e\n\u003cp\u003eThe three interior care sets are graded by what the top coat can still do – not by the year on the registration document.\u003c\/p\u003e\n\n\u003cp\u003eUp to about three years, leather is rarely dry – it needs protecting. The COLOURLOCK \"New Leather Care\" Set therefore relies on cleaning plus sealing: a thin, flexible barrier against abrasion and colour transfer. For you that means: denim transfer on light leather and early shiny spots on the bolster never get the chance to form, and the satin-matte factory feel stays.\u003c\/p\u003e\n\n\u003cp\u003eFrom three years on, the job flips. Shine then isn't caused by too little care but by compacted dirt on the surface – which is why the COLOURLOCK \"Smooth Leather Care\" Set cleans first and then follows up with UV-protective care. Just adding more care at this point seals in the greasy film instead of lifting it.\u003c\/p\u003e\n\n\u003cp\u003eIf the leather is hard, brittle and prone to cracking, the COLOURLOCK \"Classic Car Leather Care\" Set works one level deeper: the softener creeps into the hardened material and loosens stuck fibres, then leather grease puts the oils back. That's a job for weeks, not an afternoon – on decades-old classic car leather, the difference shows over several thin passes, not after the first.\u003c\/p\u003e\n\n\u003cp\u003eThe condition test takes ten seconds: feel the driver's bolster and the rear bench one straight after the other. If the bolster feels dull, rough or stiff while the rear bench is still soft, choose your set by the bolster. That's exactly where the questions that reach us come from too – entry edge, side bolster, steering wheel rim. The rest of the interior ages much more slowly.\u003c\/p\u003e\n\n\u003ch3\u003eSoft top, washing machine, sneakers: sets beyond the car\u003c\/h3\u003e\n\u003cp\u003eLeather and fabric don't stop at the seat, and some of the sets target exactly the surfaces that would otherwise only get all-purpose products.\u003c\/p\u003e\n\n\u003cp\u003eOn a fabric soft top, the COLOURLOCK \"Cabrio Care Set\" works in two stages: the cleaner concentrate is diluted up to 1:10, so a 100 ml bottle makes a good litre of working solution. The sealant then isn't sprayed on but massaged into the dry fibre with the sponge. The cured polymer film stays breathable – residual moisture from the cabin can escape outwards instead of collecting under the roof.\u003c\/p\u003e\n\n\u003cp\u003eIf the fabric isn't dirty but faded, the COLOURLOCK \"Cabrio Colour Set\" takes over, with deep cleaner, pigmented colour, cross-linker and sealant. The cross-linker reacts with the polymer chains in the colour and builds a three-dimensional network. In practice: the pigments stay in the fibre instead of running off as a grey haze in the first rain.\u003c\/p\u003e\n\n\u003cp\u003eFor removable leather items – motorbike leathers, jacket, seat cover – there's the COLOURLOCK \"Leather Wash Set\", made up of a re-greasing wash concentrate and a separate colour fixative. The fixative anchors the pigments before the wash, which runs at a maximum of 35 degrees. Without that in-between step, dark thread bleeds into light inserts, and an alkaline all-purpose detergent turns the item board-stiff.\u003c\/p\u003e\n\n\u003cp\u003eSneakers are covered by the COLOURLOCK \"Sneaker Cleaner Set\": pH-neutral foam plus leather brush, sponge and cloths for upper, sole and wiping off. Once again the foam is the real insurance – it keeps water away from the material mix of leather, mesh and glued midsole. Deliberately mild: it isn't strong enough for deeply trodden-in mud, but the colour stays on suede and mesh where it belongs.\u003c\/p\u003e\n\n\u003ch3\u003eA set doesn't replace an upholsterer or a special shade\u003c\/h3\u003e\n\u003cp\u003eSets are built for the normal case: pigmented smooth leather, manageable damage, standard colour. Outside that framework, things get thin fast.\u003c\/p\u003e\n\n\u003cp\u003eThe most common breaking point is colour. The colour kits come in factory shades, with black clearly leading the field. If you need a special shade – cognac, silver grey, two-tone interiors – you're better off combining from the individual range under \u003ca href=\"\/collections\/koch-chemie-colourlock-faerben\"\u003eDyeing \u0026amp; finishing by COLOURLOCK\u003c\/a\u003e, where tint, cross-linker and top coat can be chosen separately. For many vehicle models, COLOURLOCK also mixes original colours from a leather sample you send in.\u003c\/p\u003e\n\n\u003cp\u003eThe second limit is the substrate. Aniline leather, nubuck, rough leather and Alcantara tolerate neither the tints nor the film-forming sealants from the sets – open-pored leathers need film-free products from \u003ca href=\"\/collections\/koch-chemie-colourlock-pflege\"\u003eCare from COLOURLOCK\u003c\/a\u003e. Perforated seat surfaces are a special case of their own: we tested a tint on a piece of perforated leather, and the colour collects at the edges of the holes instead of drying evenly. Work very thin there, don't dab it on heavily.\u003c\/p\u003e\n\n\u003cp\u003eThe third limit is the damage itself. If material is missing, a load-bearing seam splits or the whole seat surface is brittle all over, no complete kit will help – liquid leather is built for individual cracks, not for fabric that's falling apart. Then you need individual products from \u003ca href=\"\/collections\/koch-chemie-colourlock-reparatur\"\u003eRepair by COLOURLOCK\u003c\/a\u003e or an upholsterer. And near airbag seams, the rule applies anyway: don't sand, the thread has to stay tear-resistant.\u003c\/p\u003e\n\n\u003cp\u003eThe fourth limit is durability. A dabbed-on tint is an excellent cosmetic fix, but it doesn't reach the abrasion resistance of a factory-baked coating. On a re-dyed driver's bolster, a clean followed by sealing every three to six months is therefore worth it. Without that rhythm, your clothes will wear through the fresh colour faster than you'd like.\u003c\/p\u003e\n\n\u003cp\u003eAn honest assessment also includes the question of whether it has to be a set at all. If your car has dark, intact factory leather and you simply want to keep it clean, a good two-in-one lotion off the shelf does the same job – quick, simple and perfectly fine for in-between care. A set pays off as soon as a cycle starts afresh: first care after buying, prep before selling, restoring an aged interior.\u003c\/p\u003e\n\n\u003ch3\u003eWhich set to start with\u003c\/h3\u003e\n\u003cp\u003eThe quickest way to a decision is to ask what's bothering you about the leather right now – not what you might need at some point.\u003c\/p\u003e\n\n\u003cp\u003eNothing bothering you and the car is young: COLOURLOCK \"New Leather Care\" Set, twice a year, done. Driver's bolster feels dull or greasy: COLOURLOCK \"Smooth Leather Care\" Set. Leather hard and dry: COLOURLOCK \"Classic Car Leather Care\" Set over several passes. If the damage is on the steering wheel rim or a small area of bolster, a small Leather Fresh kit will do; for whole interiors and several cars, the pro container is worth it.\u003c\/p\u003e\n\n\u003cp\u003eWith mechanical damage, the type decides: a clean crack with no material loss is a job for the COLOURLOCK \"Leather Glue Repair Set\" with sub-patch fabric and water-based glue. If colour loss comes on top, the COLOURLOCK \"Complete Leather Repair Set\" covers the whole chain from cleaning through filler and tint to sealing.\u003c\/p\u003e\n\n\u003cp\u003eIf you drive a convertible, that branch runs in parallel: if the top is just dirty and lets water through, the COLOURLOCK \"Cabrio Care Set\" with cleaning and sealing is enough. If the fabric is faded or blotchy, go for the COLOURLOCK \"Cabrio Colour Set\", because colour doesn't stay in the fibre without cross-linker and a final seal.\u003c\/p\u003e\n\n\u003cp\u003eIf you drive a make for which COLOURLOCK stocks its own factory colours, you'll find the right combination under \u003ca href=\"\/collections\/koch-chemie-colourlock-leder-pflege-sets\"\u003eCOLOURLOCK Leather Care Sets (all manufacturers)\u003c\/a\u003e – where the colour question from the shop tip is already answered.

A care set that holds the condition makes the dye kit unnecessary two years down the line – and that's exactly what separates a well-kept interior from a re-dyed one.\u003c\/p\u003e","products":[{"product_id":"koch-chemie-colourlock-leather-steering-wheel-set-lederreperaturset-lenkrad","title":"COLOURLOCK \"Leather Steering Wheel\" Set (leather repair kit for black steering wheels)","description":"\u003ch2\u003eCOLOURLOCK \"Leather Steering Wheel\" Set — leather repair kit for grippy, even, like-new steering wheels\u003c\/h2\u003e\n\u003cblockquote\u003e\n\u003cp\u003e\u003cem\u003eHow do you fix a worn leather steering wheel for good?

This is exactly where friction, skin oils and UV pile up every day – and the result is a smooth, slippery grip and a visibly tired look. This set doesn't just sit on the surface; it works through the job step by step: cleaning, degreasing, colour refresh and sealing all feed into each other and bring back both the look and the feel.

Over the years a wheel picks up skin oils, care products and grime that work their way deep into the surface. The included Leather Cleaner mild lifts these residues gently, without needlessly attacking the factory coating. But the real difference comes with the Degreaser: it pulls off the last oils and silicone residues completely, so the colour that follows can grab properly. This one step decides whether the result holds up or starts wearing through early. The Sanding Pad backs this up by lightly knocking back the surface so the colour takes evenly. Together with the sponges and viscose cloths you end up with a clean, receptive base – the groundwork for a pro-level result you'd usually only see in full detailing work.\u003c\/p\u003e\n\u003ch3\u003eApply leather colour and refresh the steering wheel's colour\u003c\/h3\u003e\n\u003cp\u003eOnce the surface is perfectly prepped, the key step follows: \u003cstrong\u003eapplying leather colour to the steering wheel\u003c\/strong\u003e. Leather Fresh isn't a classic paint in the usual sense but a purpose-built tint that bonds flexibly with the leather surface. That matters, because a wheel is constantly moved, stretched and stressed. Stiff coatings would crack or peel here fast. Using the included sponges you lay the colour down evenly and under control, with no streaks or hard edges. Working in layers is especially important: thin, even coats give you a natural finish and stop visible transitions. The result is a uniform colour surface that blends perfectly into the rest of the interior. This is where the set really shows its strength – it's not about covering up, it's about precisely restoring the original look.\u003c\/p\u003e\n\u003ch3\u003eSeal the leather for protection and durability on the steering wheel\u003c\/h3\u003e\n\u003cp\u003eAfter the colour refresh, the right seal decides how long it lasts – and that's exactly where Leather Shield comes in. When you \u003cstrong\u003eseal a leather steering wheel\u003c\/strong\u003e, you build an invisible protective layer that cuts down abrasion and slows dirt and skin oils from working their way back in. On cars in heavy use this step is essential, since it has a big say in how long the repair holds. The system is rounded off by the Elephant Leather Preserver, which keeps the leather supple and stops it drying out – especially important on older or already worn wheels.

On new cars or freshly detailed interiors the leather looks perfect, but it's also especially vulnerable to abrasion, colour transfer and dirt. Modern surface-pigmented smooth leather does have a protective coating, yet that's exactly what day-to-day friction, clothing and skin contact wear down over time. This set works right there: it lifts light dirt gently while building an invisible protective layer that makes the leather more resistant in the long run. The result is an interior that stays well-kept, keeps its original look and shows far less wear.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtect early instead of repairing later\u003c\/strong\u003e\u003cbr\u003eNew leather looks perfect but takes a beating day-to-day.

This is where Leather Shield plays its key role: it forms an invisible, flexible protective layer on the leather surface that acts like a barrier against abrasion, dirt and colour transfer. On light-coloured leather or hard-worked seat bolsters in particular, this seal stops early signs of wear and the typical denim staining. Unlike classic care products, this protective layer changes neither the feel nor the sheen of the leather – the silky-matt finish stays fully intact. Day-to-day that means: less cleaning, lower risk of damage and an interior that looks like new for much longer. That's exactly why this set is the first and most important step for any new car or freshly detailed leather.\u003c\/p\u003e\n\u003ch3\u003eClean leather gently car interior care\u003c\/h3\u003e\n\u003cp\u003eCleaning your \u003cstrong\u003ecar leather\u003c\/strong\u003e regularly is key to keeping the protection working over the long run. Even fine dirt particles act like an abrasive and speed up surface wear. Leather Cleaner mild is built exactly for that: it lifts dirt effectively without drying out or attacking the leather coating. Paired with the Foamer Bottle the cleaner foams up nicely, so you can spread it evenly and it works right into the structure. That keeps product use down and gives you a really controlled application. The sponges that come with it help you clean evenly, while the viscose cloths reliably pick up any residue. It's this matched interplay that gets the leather clean without putting unnecessary stress on its protective layer – a real difference from harsher cleaning methods.\u003c\/p\u003e\n\u003ch3\u003eLeather care set application result durability\u003c\/h3\u003e\n\u003cp\u003eA solid \u003cstrong\u003eleather care set for new leather\u003c\/strong\u003e shows its worth above all in the long-term effect. Combining regular, gentle cleaning with targeted sealing keeps the surface intact and resistant for far longer. Typical signs of ageing like shiny spots, discolouration or abrasion show up later and far less harshly. At the same time the natural feel stays – the leather feels neither sticky nor artificial. The key here is consistency: if you protect the leather from day one, you cut down hugely on the need for more involved work later, like colour refreshing or repairs. Should the leather still show first signs of wear, this care pairs perfectly with a \u003cem\u003eCOLOURLOCK Leather Fresh Set\u003c\/em\u003e for colour refreshing. For older leather from around three years on, it's better to switch to a more nourishing system like the \u003cem\u003eCOLOURLOCK Smooth Leather Care Set\u003c\/em\u003e, which is tuned specifically for surfaces that have already taken a beating.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eWhat's in the COLOURLOCK New Leather Care Set\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e250 ml Leather Cleaner (mild): \u003c\/strong\u003egentle cleaning for surface-pigmented smooth leather.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e100 ml Leather Shield: \u003c\/strong\u003eprotective seal against abrasion and colour transfer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3\u003cspan\u003e×\u003c\/span\u003e Cleaning \u0026amp; Application Sponge (small): \u003c\/strong\u003eeven application of cleaner and seal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2\u003cspan\u003e×\u003c\/span\u003e Viscose Cloth: \u003c\/strong\u003elint-free cloths for cleaning and wiping down.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1\u003cspan\u003e×\u003c\/span\u003e Foamer Bottle: \u003c\/strong\u003efor efficient, even foam application.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Koch-Chemie × COLOURLOCK","offers":[{"title":"8-piece set (350 ml)","offer_id":57287833551183,"sku":"D1-KCX-8810-S-01","price":31.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/8810-S-01_1.png?v=1778250923"},{"product_id":"koch-chemie-colourlock-smooth-leather-care-set-pflegeset-glattleder-ab-3-jahre","title":"COLOURLOCK \"Smooth Leather Care\" Set (care kit for smooth leather aged 3 years and up)","description":"\u003ch2\u003eCare kit against shiny spots, drying out and wear on smooth leather aged 3 years and up: COLOURLOCK \"Smooth Leather Care\" Set\u003c\/h2\u003e\n\u003cblockquote\u003e\n\u003cp\u003e\u003cem\u003eHow do you properly care for older leather in your car?

The usual giveaways are shiny patches, a slightly greasy surface or a dry feel under your fingers – that's the point where “new” starts turning into “worn in”. Here's the thing: in daily use, leather loses quality not just visually but functionally too. Friction compacts the surface, dirt particles act like fine sandpaper, and UV light pushes the ageing along on top of that. This set goes straight at those processes and gets the leather looking even again, feeling more supple and standing up far better to whatever comes next. It's the logical next step after caring for new leather – and it stops those first signs of wear from turning into real damage.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTargets greasy, shiny leather head-on\u003c\/strong\u003e\u003cbr\u003eShine doesn't come from “care” – it comes from a compacted, dirty surface.

Plenty of folks try to “mask” shiny or greasy leather with a care product instead of dealing with the cause. In reality that shine comes from a mix of dirt, skin oils and a compacted surface. That layer behaves like a film and changes both the look and the feel. The Leather Cleaner mild is built precisely to lift those residues gently, without needlessly attacking the existing leather coating. Worked in as a foam with the Foamer Bottle, the cleaner spreads evenly and can do its job without soaking the material. The Allrounder Scrubber plays a key part here: it pulls grime out of the grain without scratching or roughing up the surface. This is the step that gets the leather looking matt again and lays the groundwork for care that actually works. Skip this prep and any care stays on the surface – and over time tends to give you even more shine.\u003c\/p\u003e\n\u003ch3\u003eLeather care for cars: UV protection, suppleness and keeping the substance\u003c\/h3\u003e\n\u003cp\u003eAfter cleaning comes the real difference from basic care products: targeted \u003cstrong\u003eleather care in your car\u003c\/strong\u003e. Leather Care isn't meant to just dress the leather up cosmetically – it's there to stabilise it structurally. As leather gets older it loses flexibility, which over the long run can lead to tension, dryness and, worst case, cracks. The conditioning components in here work exactly on that, supporting the suppleness of the surface without leaving it soft or greasy. At the same time the built-in UV protection keeps the leather from fading and ageing as fast – a big factor on cars that get used a lot. The result is a more even look, a more stable surface and a noticeably nicer feel under your hand. This is the step that decides whether leather stays cared for long-term or quietly keeps getting worse.\u003c\/p\u003e\n\u003ch3\u003eLeather care set: how it differs from new-leather kits and what comes next\u003c\/h3\u003e\n\u003cp\u003eA proper \u003cstrong\u003eleather care set for older leather\u003c\/strong\u003e shows its strength above all next to systems made for new leather. Where a set like the \u003cem\u003eCOLOURLOCK \"New Leather Care\" Set\u003c\/em\u003e is mainly about protection, here it's actively about regeneration and preservation. That means: existing signs of wear get visually reduced, the surface gets stabilised and future wear slowed down. That transition is the key bit, because a lot of people step in too late – only once colour loss or damage is already showing. If the leather is already badly faded or showing first abrasions, though, care alone won't cut it anymore. In that case a \u003cem\u003eCOLOURLOCK Leather Fresh Set\u003c\/em\u003e for colour refresh is the next logical step. For deeper damage or cracks, a comprehensive approach like the \u003cem\u003eCOLOURLOCK Complete Leather Repair Set\u003c\/em\u003e is the way to go.

Unlike modern leather surfaces, what's missing here isn't just protection – it's moisture and flexibility above all. Typical signs are hard, dry leather, the first breaks on the surface or a brittle feel under your fingers – exactly what happens when the material has had its important oils and fats pulled out of it over a long time. This set goes straight at those root causes and gives the leather back what it needs: cleaning, rehydration and lasting care. The result is leather that's clearly more supple, less prone to further damage and more even-looking again.

Over the years dust, old care products and environmental residue settle into the surface and block the pore structure. This is exactly where most mistakes happen: cleaners that are too aggressive or the wrong method can dry out or damage the already weakened leather even more. The Leather Cleaner mild is dialled in for precisely this situation and lifts dirt gently, without attacking the substance any further. The leather brush backs this up, working right into the structure and freeing residue you'd never reach with a cloth alone. Paired with the Foamer Bottle you lay the cleaner down as a controlled foam, so the leather doesn't get soaked needlessly. This step is the one that counts, because only clean, prepped leather can take in the care products that follow and actually let them work.\u003c\/p\u003e\n\u003ch3\u003eOld Leather Softener: making leather supple again, rehydrating\u003c\/h3\u003e\n\u003cp\u003eThe real difference with old leather comes down to \u003cstrong\u003erehydrating leather\u003c\/strong\u003e. As the years go on the material loses its natural fats and turns hard, brittle and prone to cracks. That's exactly where the Old Leather Softener comes in. It works deeper into the leather structure and helps make hardened areas supple again. This step matters, because stiff leather can no longer flex with movement – the upshot is tension that leads to breaks down the line. With targeted use the leather gets flexible again and copes with stress better. The key is an even, patient application, since this step needs time to work fully. This is where the difference to classic care products shows: it isn't about a quick shine, it's about lasting recovery of how the material behaves.\u003c\/p\u003e\n\u003ch3\u003eClassic-car leather care: protection, durability and kept substance\u003c\/h3\u003e\n\u003cp\u003eAfter rehydration comes the step that decides the long game: \u003cstrong\u003eclassic-car leather care\u003c\/strong\u003e. The Elephant Leather Preserver feeds the leather with high-grade care components that work deep into the surface and keep it supple from there. At the same time a protective layer forms that guards the leather against drying out again and against outside influences. With cars that get used rarely or seasonal classics in particular, that protection is key, since long lay-ups can speed the ageing on. The result is leather that feels more natural again, looks more even and is clearly less prone to fresh damage. Worth understanding: this set is meant for care and preservation.

The set combines a slightly acidic Leather Cleaner Mild, a water-based polymer dye, and a Leather Protector into a complete three-phase workflow. After the water evaporates, the dye forms a flexible polymer mesh on the leather surface, which optically fills micro-fine scratches and replenishes the color in faded areas.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003epH just below the fiber pH of leather.\u003c\/strong\u003e Smooth leather is acid-tanned and has a natural pH range between 4.5 and 5.5.

The seat is cleaned with Leather Cleaner Mild, then the dye is applied directly, and four weeks later the color peels off the bolster. The missing step is degreasing. Every smooth leather has an invisible layer of skin oils, old care lotions, and silicones that the mild cleaner does not remove. From our experience, the strict rule is: after cleaning, it is essential to degrease with COLOURLOCK Leather Cleaning Spirit. The quick check before dyeing is the tape test with painter's tape—if the tape doesn't stick, there's still grease, and you need to clean again. Only then apply the dye with a sponge, dabbing in wafer-thin layers, with a hairdryer between layers. And without exception, 24 hours must pass before the Protector is applied.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eThree phases, one sequence that is non-negotiable\u003c\/h3\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eCOLOURLOCK Leather Fresh C \u0026amp; P Set\u003c\/strong\u003e is not a miracle cure for Sunday afternoon, but a continuous three-phase workflow. Anyone who skips a phase will reliably ruin the result.\u003c\/p\u003e\n\n\u003cp\u003ePhase 1 is cleaning with \u003cstrong\u003eLeather Cleaner Mild\u003c\/strong\u003e. The formulation is a mild anionic surfactant system with a slightly acidic pH, so that the fiber does not swell. Professionals always put the cleaner into a foam dispenser (Foamer Bottle), because the drier foam prevents the leather from getting soaked and becoming stiff like a board when drying.\u003c\/p\u003e\n\n\u003cp\u003ePump foam onto a slightly damp sponge, work it in with a soft leather brush in circular motions, then immediately remove it with a dry microfiber cloth. Do not let it dry, otherwise edges will form.\u003c\/p\u003e\n\n\u003cp\u003ePhase 2 is degreasing with Leather Cleaning Spirit. This component is not included in the set and must be purchased separately. Nevertheless, it is not an optional step. The cleaning spirit dissolves skin oils, sunscreen residues, and old silicone-based care lotion from the surface.\u003c\/p\u003e\n\n\u003cp\u003eThe polymer dye adheres permanently only to a degreased surface. The tape test with painter's tape is a quick quality check: if the tape sticks, the surface is grease-free and you can proceed.\u003c\/p\u003e\n\n\u003cp\u003ePhase 3 is dyeing with the \u003cstrong\u003eLeather Fresh\u003c\/strong\u003e polymer. Shake the bottle vigorously, as the water-based polymer dispersion tends to stratify. Wet the enclosed sponge, apply the material in wafer-thin layers by \u003cem\u003edabbing\u003c\/em\u003e or massaging in gentle circular movements—never spread, otherwise streaks will form.\u003c\/p\u003e\n\n\u003cp\u003eDry with a hairdryer on a medium setting between each layer. For heavily worn bolsters, three to four thin layers are realistic. Then allow to polymerize for a full 24 hours before applying the Protector. If you want to care for the cockpit and door panels in parallel, combine the set with the \u003ca href=\"\/collections\/lederpflege\"\u003eleather care\u003c\/a\u003e collection or with the \u003ca href=\"\/collections\/innenraumreiniger\"\u003einterior cleaners\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003ePolymer film, not filler. Three hard limits\u003c\/h3\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eCOLOURLOCK Leather Fresh\u003c\/strong\u003e dye is a polymer film, not a repair filler. Three substrates are taboo, three technical limits must be known.\u003c\/p\u003e\n\n\u003cp\u003eFirst limit: open-pore leather. Aniline leather, nubuck, suede, and velour leather immediately draw the water-based polymer dispersion deep into the fiber, without forming a film. The result is dark, patchy discolorations that cannot be removed without residue.\u003c\/p\u003e\n\n\u003cp\u003eBefore each application, perform the water drop test: place a drop of clear water on an inconspicuous area. If it absorbs within 30 seconds, the leather is open-pore. In that case, use COLOURLOCK Aniline \u0026amp; Suede Protector, not the C \u0026amp; P Set. Synthetic microfiber fabrics like Alcantara are also on the negative list.\u003c\/p\u003e\n\n\u003cp\u003eSecond limit: the set does not repair cracks or holes. The polymer matrix has a minimal filling effect for micro-fine surface scratches in the leather finish, but none for deep fiber damage.\u003c\/p\u003e\n\n\u003cp\u003eIf you want to close a hole in the seat bolster, you first need COLOURLOCK Fluid Leather (liquid leather) as a filler and then work with Leather Fresh for color matching. Without this preliminary work, the hole will remain visible, because the dye only forms a thin film over the wound and will tear when the seat is sat on for the first time.\u003c\/p\u003e\n\n\u003cp\u003eThird limit: no radical color changes. If you want to recolor black leather to beige, you need solvent-based spray paints with a spray gun, not the water-based C \u0026amp; P Set. The dye matches faded and worn areas to the original color—it is restoration, not redesign.\u003c\/p\u003e\n\n\u003cp\u003eOne exception is the \"Neutral\" base: 100 ml of colorless dye can be mixed with about 20 to 30 percent color pigments if you really need a special shade for a restoration project. If you want additional protection against jeans abrasion after dyeing, combine the set with microfiber cloths and brushes from our \u003ca href=\"\/collections\/zubehoer-detailing\"\u003eaccessories\u003c\/a\u003e range.\u003c\/p\u003e\n\n\u003ch3\u003eProsumers, Smart Repair specialists, and saddlers\u003c\/h3\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eCOLOURLOCK Leather Fresh\u003c\/strong\u003e leather care set serves three clearly defined target groups. Anyone outside these three profiles will either overchallenge or underchallenge the set.\u003c\/p\u003e\n\n\u003cp\u003eFirst target group: Prosumers and hobby mechanics with a special restoration object. The greasy steering wheel of a youngtimer, the worn bolster in a 10-year-old BMW, the faded seat in a Mercedes E-Class Convertible. Anyone who invests a full Saturday and adheres to the three-phase logic will achieve a smart repair level without a smart repair bill.\u003c\/p\u003e\n\n\u003cp\u003eSecond target group: Smart repair specialists and semi-commercial detailing studios. They work with a spray gun or airbrush instead of a sponge, achieving a seamless factory finish without sponge texture on the leather. The OEM color database makes the set the de facto industry standard for color-accurate restoration.\u003c\/p\u003e\n\n\u003cp\u003eThird target group: Saddlers and leather restorers for larger restorations. Classic car interiors, vintage car cockpits, 80s Mercedes SL seats. In combination with Fluid Leather as a filler and, if necessary, Elephant Leather Preserver for extreme re-oiling, the set covers the complete tool chain for full restoration.\u003c\/p\u003e\n\n\u003cp\u003eCompared to the competition, the set is clearly positioned. Geist. Easy Colour Restorer is cheaper and does not require a separate topcoat due to self-crosslinking polymers, but it lacks the vehicle-specific OEM color database. GYEON Q²M Leather Set is a ceramic coating for prevention on intact new leather, not a repair system.\u003c\/p\u003e\n\n\u003cp\u003eLMX\/Coralux Keralux dominates the home furniture market with alkaline cleaners, not the automotive sector with pH-compliant formulations. If you need color restoration to original tone, the C \u0026amp; P Set is the right choice. If you want to protect new leather, a ceramic sealant is better.\u003c\/p\u003e\n\n\u003cp\u003eOne practical trick that no manufacturer brochure reveals: after the dye has dried and before the Protector, gently run the included leather sanding pad over the surface without pressure. This smooths the polymer surface, eliminates any remaining micro-roughness, and restores the fiber's original, almost factory-like feel. Only then is the Protector applied as a long-term sealant.\u003c\/p\u003e","brand":"Koch-Chemie × COLOURLOCK","offers":[{"title":"Neutral \/ set","offer_id":57637092262223,"sku":"D1-KCX-8805-S-01","price":128.99,"currency_code":"EUR","in_stock":true},{"title":"Black \/ set","offer_id":57637092294991,"sku":"D1-KCX-8805-S-01-F034","price":76.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/8805-S-01_1.png?v=1778249509"},{"product_id":"koch-chemie-colourlock-leather-glue-repair-set","title":"COLOURLOCK \"Leather Glue Repair Set\"","description":"\u003ch2 id=\"speakable-headline\"\u003eStructurally secure cracks in car leather with leather glue, backing fabric, and brush\u003c\/h2\u003e\n\n\u003cblockquote id=\"speakable-summary\"\u003e\n  \u003cp\u003e\u003cem\u003eWhat is the COLOURLOCK Leather Glue Repair Set?

The box contains three components: a water-based leather glue in a 20-gram container, a pre-cut tear-resistant textile backing fabric, and two fine mini brushes for precise application. The glue uses a water-based polymer dispersion instead of volatile solvents. This makes it odor-neutral, non-flammable, and preserves the natural re-greasing agents in the leather collagen.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePermanently elastic adhesive seam instead of brittle, hard bonding.\u003c\/strong\u003e As it dries, polymer chains mechanically interlock with the open leather fibers and the backing fabric. In short: the bond remains rubber-elastic like the leather itself. This means for you: when getting into the seat bolster, the glued area stretches with it and does not tear again on the first day of stress, as happens with superglue repairs.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOdor-neutral and without pungent fumes in the interior.\u003c\/strong\u003e Classic saddler contact adhesives use volatile organic compounds, i.e., light solvents, which leave a pungent smell in the car for days.

This means for you: the car is usable again after two hours, and no persistent glue smell permeates the seat upholstery and headliner.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComplete set for an average seat bolster repair.\u003c\/strong\u003e Tear-resistant backing fabric and two mini brushes are included directly in the set — no separate accessory purchase from saddler specialists is necessary. The 20-gram tube is sufficient for three to six smart repair jobs on seat bolsters, backrest edges, or leather steering wheels, depending on the length of the crack. If you are restoring an entire seat, plan for a second set for very long crack chains.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003ePractical tip from Detailing1:\u003c\/strong\u003e We see the same pattern in every second call regarding leather repair. The customer sees the crack, squeezes a thick drop of glue into it, presses it down with their hand — four weeks later, the crack is open again or a dark shadow appears on the visible side.\u003c\/p\u003e\n  \u003cp\u003eFrom our experience: the two crucial factors are degreasing and thin application. First, the adhesive edge must be stripped bare with COLOURLOCK Degreaser — otherwise, the water-based glue will bead off invisible skin fats and leather care residues. Second, the glue is sparingly applied with the mini brush between the leather fiber and backing fabric, never dropped directly into the crack from above.\u003c\/p\u003e\n  \u003cp\u003eFor thin aniline and nappa leather, additionally: rather two thin layers with a short flash-off time each than one thick one that bleeds through and leaves a shadow on the surface. This is the discipline that separates the set from a DIY attempt.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eCar Leather Glue in Four-Phase Smart Repair\u003c\/h3\u003e\n\n\u003cp\u003eThe \u003cstrong\u003ecar leather glue\u003c\/strong\u003e is not a tool for rushed actions, but the structural core of a timed four-phase workflow. If you skip a phase, you will see the result after the first week of driving.\u003c\/p\u003e\n\n\u003cp\u003ePhase one is preparation. The crack and surrounding adhesive edges are thoroughly cleaned with Leather Cleaner Mild or Strong, then degreased with COLOURLOCK Degreaser. The Degreaser is a special cleaning benzine, a volatile solvent that removes deep-seated waxes, silicones, and body fats without dissolving the leather color. Practical: without this step, the water-based glue will not find a mechanical anchor in the leather and will bead off.\u003c\/p\u003e\n\n\u003cp\u003ePhase two is inserting the backing fabric for tension cracks. Cut the supplied textile fabric two to three centimeters larger than the crack, mark the center with a pen, fix it from above with a needle, and slide it centrally under the leather with a narrow spatula. The marking serves as a check: if it is centered in the crack, the fabric lies neatly under both crack edges.\u003c\/p\u003e\n\n\u003cp\u003ePhases three and four are glue application and curing. The glue is sparingly brushed with the mini brush between the backing fabric and the back of the leather, allowed to flash off for two to five minutes, then the crack edges are pressed onto the backing fabric for 15 to 30 minutes with even pressure — clothes pegs, a sandbag, or a small steel block can help. Initial load-bearing capacity after about two hours, full final strength after 48 hours. Only then can filling with Liquid Leather or further leather care steps be carried out. Processing temperature between 15 and 25 degrees — frost destroys the emulsion, heat above 30 degrees causes the glue to set too early.\u003c\/p\u003e\n\n\u003ch3\u003eSmooth and synthetic leather yes, aluminum door panels no\u003c\/h3\u003e\n\n\u003cp\u003eThe leather glue is highly specialized. Four substrates are approved — and four areas are hard limits that even the best workflow cannot overcome.\u003c\/p\u003e\n\n\u003cp\u003eApproved are \u003cstrong\u003esmooth leather\u003c\/strong\u003e such as BMW Dakota, Mercedes Nappa, or Audi Valcona — the closed pigment layer holds the glue on the surface, which makes butt-joint processing controllable. Also approved are \u003cstrong\u003esynthetic leather and vinyl\u003c\/strong\u003e such as MB-Tex, Sensatec, or Skai, where the glue binds the torn PVC fabric to the backing material underneath. For \u003cstrong\u003eaniline leather\u003c\/strong\u003e — open-pored, undyed full leather without a lacquer layer — maximum economy is required, because the glue immediately penetrates the pores and darkens the area. For \u003cstrong\u003esuede\u003c\/strong\u003e such as Alcantara, Nubuck, or Velour, the glue is applied exclusively to the back between the fiber and the backing fabric — if it gets on the raised pile, the area clumps into a hard crust that cannot be brushed out.\u003c\/p\u003e\n\n\u003cp\u003eWhat doesn't work: hard plastics like ABS door panels, bare metal, glass, and exterior paints. The water-based dispersion finds no anchor on closed, inflexible surfaces. If an entire leather cover detaches extensively from the door panel, saddlers tend to use heat-activated contact adhesives — that's a different league and a different tool. And: with petrified leather that has been dehydrated and structurally destroyed by years of UV radiation, even this glue cannot work wonders. If the fiber breaks in your hand, a new saddler cover is the next sensible step.\u003c\/p\u003e\n\n\u003cp\u003eCompared to water-based competitor glues such as Geist. Leather Glue, the chemical basis is almost identical. The system advantage with COLOURLOCK lies in workflow integration: leather glue, Liquid Leather filler, Leather Fresh dye, and leather sealant are coordinated as a closed chain — no mix-and-match risk between brands. If you want to complement the appropriate \u003ca href=\"\/collections\/innenraum\"\u003einterior\u003c\/a\u003e workflow all around, you will find the coordinated cleaners and care products for the entire seating package in the range.\u003c\/p\u003e\n\n\u003ch3\u003eClassic car restorers, detailers, ambitious DIY repairers\u003c\/h3\u003e\n\n\u003cp\u003eThe set serves three clear target groups. If you don't fit into any of these three categories, you are better off with a complete service from a saddler or leather specialist.\u003c\/p\u003e\n\n\u003cp\u003eFirst target group: \u003cstrong\u003eclassic car and youngtimer restorers.\u003c\/strong\u003e Anyone who owns a Porsche 911 Targa, a BMW E30, or a Mercedes W107 SL with the original leather interior does not want to go to a saddler for a new cover — the original patina is irrevocably lost and the car loses visible character. Smart repair with the COLOURLOCK set is the only sensible choice here. In the relevant detailing forums, the product is the undisputed gold standard with a grade of 1.5.\u003c\/p\u003e\n\n\u003cp\u003eSecond target group: \u003cstrong\u003eused car dealers and semi-professional detailers.\u003c\/strong\u003e Torn entry bolsters on BMW M-Sport seats or Mercedes AMG seats are the typical customer fright before a test drive appointment. With the set, the damage can be repaired optically and structurally in two to three hours of work plus curing — the vehicle value increases many times over the set investment. Mini brushes and backing fabric are included directly, no additional accessory purchase is necessary.\u003c\/p\u003e\n\n\u003cp\u003eThird target group: \u003cstrong\u003eambitious convertible and leather enthusiasts with a craftsmanship claim.\u003c\/strong\u003e Those who invest the effort, disciplinedly carry out the preparation, and respect the 48 hours of final strength will end up with a repair that lasts two to three seasons. However, heavily stressed entry bolsters on the driver's seat remain inherent weak points — due to daily sliding in and turning, even a professionally glued seam may require touch-ups after twelve to 24 months. This is not a weakness of the set, but physics of shear stress. Those who prefer to tackle the damage preventively will find the suitable \u003ca href=\"\/products\/koch-chemie-leather-star-ls-lederpflege\"\u003eLeather Star leather care\u003c\/a\u003e in the range for regular re-greasing as crack prevention.\u003c\/p\u003e\n\n\u003cp\u003eThe one professional trick that is not in any manufacturer's brochure: for extremely stressed seat bolsters, we combine the gluing with the thermo-fixing method. Insert the backing fabric as usual, brush on a thin layer of glue, let it flash off — and when pressing, use a slightly warmed metal block preheated to oven-low instead of just your bare hand. The thermal shock freezes the polymer in its final form and prevents slipping under tensile load. Especially with E30 sports seats or Audi RS bolsters under constant load, this is the gesture that lasts for years instead of tearing open again after one season. This is the difference between a quick repair and a smart repair result at a saddler's level.\u003c\/p\u003e","brand":"Koch-Chemie × COLOURLOCK","offers":[{"title":"set","offer_id":57637092458831,"sku":"D1-KCX-8807-S-01","price":25.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/8807-S-01_1.png?v=1778249510"},{"product_id":"koch-chemie-colourlock-leather-wash-set","title":"COLOURLOCK \"Leather Wash Set\"","description":"\u003ch2 id=\"speakable-headline\"\u003eMachine Washing Removable Leather Parts Without Color Bleeding\u003c\/h2\u003e\n\n\u003cblockquote id=\"speakable-summary\"\u003e\n  \u003cp\u003e\u003cem\u003eWhat is the COLOURLOCK Leather Wash Set?

The concentrate follows a tanner's recipe and returns fats to the leather during washing, instead of rinsing them out. The fixative applies a protective layer to the pigments before washing, preventing dark colors from bleeding into light inlays during the 35-degree rinse.\u003c\/p\u003e\n\n\u003cp\u003eRegular heavy-duty detergents are alkaline and strip the leather of its natural softeners. The result is a rock-hard piece that can no longer be worn or upholstered. The COLOURLOCK set is the counter-logic to this: slightly acidic, re-greasing, with a separate color lock. The brand has been part of Koch-Chemie since the end of 2023; the formulation has remained unchanged after the takeover, and the containers now feature the white KCX design.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwo-bath workflow to prevent color bleeding.\u003c\/strong\u003e The included 100 ml fixative is prepared in a separate tub with 5 to 10 liters of lukewarm water before washing.

It doesn't work there. The fixative needs standing water and 60 minutes to anchor itself in the leather fibers. Prepare 50 ml in a tub with 5 to 10 liters of lukewarm water, place the leather parts in it, and then transfer them moist into the drum \u003cem\u003ewithout rinsing\u003c\/em\u003e.\u003c\/p\u003e\n  \u003cp\u003eFrom our experience: throwing two to three clean tennis balls into the cold air dryer breaks up bonded fibers faster. The leather is supple after 30 minutes instead of two days of air drying. No manufacturer writes this trick into the official instructions.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eFour phases from pre-treatment to milled leather\u003c\/h3\u003e\n\n\u003cp\u003eThe set only works if the four phases of pre-wash, fixative bath, machine wash, and milling are consistently followed sequentially. Shortcutting will either ruin the color or the structure of the leather.\u003c\/p\u003e\n\n\u003cp\u003eHeavily soiled areas such as collars, cuffs, and linings are first pre-treated undiluted with the concentrate and a soft leather brush. Without this pre-wash, coarse dirt will simply remain during the machine wash.\u003c\/p\u003e\n\n\u003cp\u003eThen comes the fixative bath in a tub: 50 ml in 5 to 10 liters of lukewarm water, 60 minutes soaking time, move briefly every 15 minutes. The moist parts are then transferred directly into the drum without rinsing, along with 80 to 125 ml of concentrate on a wool wash cycle at a maximum of 35 degrees.\u003c\/p\u003e\n\n\u003cp\u003eHigher temperatures cause the leather proteins to curdle and the material shrinks irreversibly. We regularly hear of covers that came out of the drum several clothing sizes smaller because the water was too warm or drying was done on a heater. This is not a marketing note, it's a physical limit.\u003c\/p\u003e\n\n\u003cp\u003eAfter spinning, the critical phase follows: milling. The semi-dry leather is stretched and kneaded in all directions until the fibers are flexible again. Completely dry pieces can alternatively be tumbled soft for 15 to 30 minutes in a dryer with cold air, turned inside out, never with heat. Air drying takes one to two days, lying flat on towels or hanging shape-stable at room temperature, no heater, no sun.\u003c\/p\u003e\n\n\u003cp\u003eIf you want to add aftercare to the workflow, the \u003ca href=\"\/products\/koch-chemie-colourlock-care-waterproofing-oil-pflegeol-impragnierung\"\u003eCOLOURLOCK Care \u0026amp; Waterproofing Oil\u003c\/a\u003e is the right impregnation for smooth leather. Without impregnation, the fiber remains supple but loses the water repellency that protects the leather from subsequent soiling in everyday use.\u003c\/p\u003e\n\n\u003ch3\u003eStructural wash dissolves dirt, not migrated pigments\u003c\/h3\u003e\n\n\u003cp\u003eThe Leather Wash Set removes sweat, sebum, and road dust from the leather structure. Chemical pigment migrations such as denim dye transfer on light nappa are beyond its reach.\u003c\/p\u003e\n\n\u003cp\u003eStandard applications include sweaty motorcycle suits and pilot jackets, classic leather cases, removable vintage car covers, leather gloves with ingrained sweat marks, historical saddle straps, and equestrian equipment. Lambskin with firm tanning is also suitable. Forums such as autopflegeforum.eu and fahrzeugpflegeforum.de refer to the concentrate as a reference for machine leather washing. Users consistently report that the leather does not harden with correct drying.\u003c\/p\u003e\n\n\u003cp\u003eUnwashable remain open-pore aniline leathers in strong composite, very porous old leathers, exotic leather types, and furs with washable tanning. In these substrates, the water also dissolves the tanning, and the piece loses its structure. If dark pigment spots are not superficial but have migrated into the leather color, even intensive washing will not help. Then re-pigmentation with COLOURLOCK Leather Fresh is the next step.\u003c\/p\u003e\n\n\u003cp\u003eA second honest limitation: deeply ingrained mold or mildew odor in foam padding cannot be removed by washing alone, because the spores do not even reach the leather; they are under the cover. Here, the padding must be disassembled, otherwise the odor will return after three days.\u003c\/p\u003e\n\n\u003cp\u003eIf, on the other hand, only a quick wipe-down cleaning of the car interior without disassembly is required, then the \u003ca href=\"\/products\/koch-chemie-colourlock-leather-cleaner-mild-lederreiniger\"\u003eCOLOURLOCK Leather Cleaner Mild\u003c\/a\u003e is the right choice, as it works on permanently installed car seats. If you need to wash dark and light leather parts separately and only need the fixative lock individually, choose the \u003ca href=\"\/products\/koch-chemie-colourlock-leather-fixative-farbfixierer\"\u003eCOLOURLOCK Leather Fixative\u003c\/a\u003e in a single bottle.\u003c\/p\u003e\n\n\u003ch3\u003eFor saddlers and restorers, not for wipe-down care\u003c\/h3\u003e\n\n\u003cp\u003eThe set is aimed at users who machine wash removable leather parts and invest three hours plus drying time. For everything else, it is too elaborate.\u003c\/p\u003e\n\n\u003cp\u003eThe main target group includes saddleries, trained leather reconditioners, restorers of classic convertibles and vintage cars, and motorcycle suit cleaners. The assortment of 250 ml concentrate plus 100 ml fixative is sufficient for three to five machine washes or a larger saddler order. In regular wash-and-wax detailing on permanently installed car seats, the set plays no role. Seats cannot be put in the machine; here, the Leather Cleaner Mild is already ready in the wiping tray.\u003c\/p\u003e\n\n\u003cp\u003eHobby enthusiasts who clean a motorcycle suit once a year also benefit, provided they take the afternoon for it. Three hours of active time plus one to two days of drying is the honest effort estimate; less is not realistic.\u003c\/p\u003e\n\n\u003cp\u003eAn important consequence that reconditioners should discuss with the end customer before each job: scratches, fading, and patina concealed by dirt will become prominently visible after deep washing. A leather wash often necessitates subsequent color refreshment with Leather Fresh, otherwise the customer will be more disappointed after cleaning than before. A photo log of the prior condition, reviewed with the customer, prevents the expectation gap between \"five hours of work\" and \"looks like new.\"\u003c\/p\u003e\n\n\u003cp\u003eThe one Detailing1 insight that no marketing brochure writes: after every leather wash cycle, the machine itself must be degreased. The concentrate contains a lot of lanolin, and at 35 degrees, a sticky grease film inevitably remains in the drum and hoses. Without post-cleaning, it will ruin the next textile wash, often only two washes later, when shirts suddenly come out of the drum greasy. A blank run at 60 to 90 degrees with a strong degreasing heavy-duty detergent is sufficient.\u003c\/p\u003e\n\n\u003cp\u003eThis is the hour of effort between a satisfied saddler customer and a family with greasy shirts. Exactly where most people shorten the workflow. Whoever buys the leather detergent set buys not only the two bottles, but the commitment to consistently complete the workflow, from the fixative bath to the 35-degree limit to the subsequent machine cleaning cycle.\u003c\/p\u003e","brand":"Koch-Chemie × COLOURLOCK","offers":[{"title":"set","offer_id":57637092491599,"sku":"D1-KCX-8809-S-01","price":31.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/8809-S-01_1.png?v=1778249510"},{"product_id":"koch-chemie-colourlock-sneaker-cleaner-set","title":"COLOURLOCK \"Sneaker Cleaner Set\"","description":"\u003ch2 id=\"speakable-headline\"\u003eSneaker Cleaner Set for Smooth Leather, Mesh, and Suede without Material Damage\u003c\/h2\u003e\n\n\u003cblockquote id=\"speakable-summary\"\u003e\n  \u003cp\u003e\u003cem\u003eWhat is the COLOURLOCK Sneaker Cleaner Set?

The cleaner is in a 200 ml foam dispenser and operates at pH 7.0, which is precisely the same value as water and healthy skin. The set comes with a soft leather brush, cleaning sponge, and two viscose cloths in a box.

This alkalinity attacks the tanning agents in the leather, makes the material brittle after drying, and can fade colors on mesh and suede. The Sneaker Cleaner is precisely calibrated to pH 7.0. For you, this means: no embrittlement, no fading, no bleeding. The honest trade-off: this mildness is not enough for deeply ingrained mud.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFoam dispenser as material insurance.\u003c\/strong\u003e Around 45 percent of all shoe reconditioning errors occur due to over-wetting. The problem behind this: the mid-sole adhesive dissolves on a water basis. As soon as the upper material becomes saturated, the water runs into the seam, and the sole detaches from the shoe. The 200 ml dispenser dispenses dense micro-foam instead of free liquid. Practical: you control the amount of water via the tool, not via the spray gun. No open adhesives on the sole edge.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeritage from the Leather Centre, now from Unna.\u003c\/strong\u003e COLOURLOCK has been fully part of Koch-Chemie since October 2023 and has been produced at the filling lines in Unna since the third quarter of 2024. For you, this means: laboratory control at the level of the Koch-Chemie vehicle line, the same batch documentation as for wheel cleaners in the car aisle. The set thus no longer entails manufacturing tolerances, but industrial reproducibility.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003ePractical tip from Detailing1:\u003c\/strong\u003e We often see sneakers ruined by incorrect brushes. Detailers instinctively reach for the hard synthetic brush for car upholstery because it's already on the shelf. On mesh, this guarantees pilling, i.e., lint formation in the fabric; on Nappa leather, the hard bristles cause irreversible micro-scratches.\u003c\/p\u003e\n  \u003cp\u003eThe rule from our practice: zone separation. The included soft COLOURLOCK brush is only for smooth leather and soles. For mesh and knit, use the sponge from the set and dab instead of scrubbing. Suede must be treated with a crepe or brass brush in one direction after foam cleaning. Otherwise, the fine fibers will stick together during drying, and you'll think the cleaner has destroyed the material. In reality, the fibers are just lying flat and need to be combed up.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eFoam on the tool, not on the shoe\u003c\/h3\u003e\n\u003cp\u003eThe Sneaker Cleaner Set works in three clearly separated phases. Dry pre-wash, main wash as foam, air-drying at room temperature. First, remove the shoelaces, then use a dry brush or a worn-out soft brush to remove coarse dust and loose dirt from the upper material and sole. This dry phase is the first material protection: sand grains that end up in the wet foam act like micro-fine sandpaper on any substrate.\u003c\/p\u003e\n\n\u003cp\u003eIn the second step, the foam from the 200 ml dispenser is pumped directly onto the moist brush or moist sponge, never directly onto the shoe itself. This is the central anti-over-wetting rule: you only apply the amount of foam that the tool absorbs, not the amount that the dispenser currently dispenses. In circular, gentle motions, the foam dissolves skin oils, road oils, and grass residues.\u003c\/p\u003e\n\n\u003cp\u003eThe underlying mechanism is micelle formation. The cleaning molecules form tiny spheres that enclose fat inside and are carried away in the water. Translated: what was just sticking is now sitting on top as laden foam, you just have to remove it.\u003c\/p\u003e\n\n\u003cp\u003eThe dwell time after application is 5 to 10 minutes. Then, remove the dirty foam with a clean microfiber cloth or a damp viscose cloth. For heavier soiling, rinse briefly with lukewarm water, about 30 degrees. Not hot and not directly under the tap. Both flush too much water into the mid-sole adhesive seam, and both effects from the second key benefit occur.\u003c\/p\u003e\n\n\u003cp\u003eThe application window is narrower than many think: 15 to 25 degrees Celsius. Direct sunlight dries the foam before removal and leaves surfactant residues, i.e., slight streaks at the edge of the cleaned surface. Below 15 degrees, the foam quality breaks down, the dispenser only delivers liquid drops instead of dense micro-mousse. Do not place the shoe outside in between if your care room is cold. Instead, extend the dwell time and continue working indoors.\u003c\/p\u003e\n\n\u003cp\u003eIf the dirt is extreme, the cleaner shows its true colors: the cleaning molecules are laden with dirt after one minute and can't absorb anything more. Fresh foam on top will only smear. In that case, rinse the first pass completely, let it air dry briefly, and start a second pass with fresh foam. No second push from the dispenser onto an already smeared shoe.\u003c\/p\u003e\n\n\u003ch3\u003eMild remains mild and the honest limits\u003c\/h3\u003e\n\u003cp\u003eCOLOURLOCK communicates it very clearly itself: the Sneaker Cleaner is a tool for fair-weather and lifestyle sneakers, not an all-purpose liberator for dirty everyday shoes. Anyone who doesn't accept this will be disappointed after the first pass and will brush harder out of frustration. The second application error arises from the first.\u003c\/p\u003e\n\n\u003cp\u003eThree practical limits. First: \u003cstrong\u003edeeply ingrained mud and old oil stains\u003c\/strong\u003e. Here, the mild surfactant power is not enough. For heavily soiled leather areas, Koch-Chemie itself refers to the significantly stronger COLOURLOCK Strong Leather Cleaner with an alkaline active ingredient base. Anyone looking for the same concentrate for car interiors and sneakers will find the \u003ca href=\"\/products\/koch-chemie-pol-star-textil-leder-und-alcantarareiniger-po\"\u003eKoch-Chemie Pol Star\u003c\/a\u003e from the Classic line more economical. Detailers mix it 1:10 for sneaker cleaning in large liter containers.\u003c\/p\u003e\n\n\u003cp\u003eSecond: \u003cstrong\u003eyellowed white soles\u003c\/strong\u003e. The yellowing of old mid-soles is UV oxidation of the plastic, i.e., chemical aging due to sunlight over years. This is not a dirt film. Pure surfactant cleaners cannot tackle chemical aging. If you want the sole to be white again, you need either bleach-based sole cleaners that attack the leather upper material, or a UV oxidation treatment with hydrogen peroxide and sunlight. Both are outside the scope of this set. What the cleaner does very well, however, is remove white, light dirt film and skin oil from the sole.\u003c\/p\u003e\n\n\u003cp\u003eThird: \u003cstrong\u003egenuine color refreshment on suede and nubuck\u003c\/strong\u003e. If the suede sneaker looks faded at the tip, this is mechanical fiber abrasion, not dirt. The cleaner removes surface dirt but cannot straighten the microscopically flattened fibers. After foam cleaning, dry, then comb with a fine crepe or brass brush in one direction. The feel returns, the color does not.\u003c\/p\u003e\n\n\u003cp\u003eFor genuine color refreshment, there is the separate COLOURLOCK Suede Color line. Immediately after cleaning, for smooth leather sneakers, a care product like the \u003ca href=\"\/products\/koch-chemie-colourlock-leather-fresh-set-xs\"\u003eCOLOURLOCK Leather Fresh Set XS\u003c\/a\u003e is useful. It restores fat to the leather matrix that was rinsed out during cleaning.\u003c\/p\u003e\n\n\u003cp\u003eHot air, radiators, and hairdryers are the fourth trap. Around 25 percent of all drying damage occurs due to forced hot drying. Leather shrinks, sole adhesives become soft, and the mesh wrinkles. The only safe method: let it dry at room temperature, maintaining the shape with cedar shoe trees. Cedar wood absorbs moisture from inside the shoe and simultaneously stabilizes its shape. The professional version of the newspaper trick, only without soggy paper in the morning.\u003c\/p\u003e\n\n\u003ch3\u003eSneakerheads, hobby detailers and the appropriate product range environment\u003c\/h3\u003e\n\u003cp\u003eThe Sneaker Cleaner Set targets three target groups with different expectations. Sneakerheads and collectors buy it to preserve the value of high-priced or limited models. If a pair of Air Jordans or Yeezys costs a three-figure sum, a set with documented Reach compliance is the rational insurance against material damage. Here, maximum cleaning power is not what counts, but minimal material stress.\u003c\/p\u003e\n\n\u003cp\u003eHobby detailers transfer their scientific approach from vehicle detailing to their wardrobe. If someone washes their convertible in summer with pH-neutral shampoo and a two-bucket method, they don't want to ruin their sneakers with dishwashing detergent and a machine wash. The set fits into the existing toolbox. The foam dispenser follows the same logic as the foamer for rim care, and microfiber cloths are already there anyway. For car interior care, the sneaker set is a lifestyle extension. In the catalog, you will find the set in our \u003ca href=\"\/collections\/lederpflege\"\u003eLeather Care category\u003c\/a\u003e, where the complementary care products are also located.\u003c\/p\u003e\n\n\u003cp\u003eCompared to the competition, COLOURLOCK deliberately does not position itself as a hype brand. Jason Markk and Reshoevn8r from the USA cost similarly but deliver liquid concentrates that must be mixed with water in a bowl. This brings the risk of over-wetting back through the back door. TikTok hype brands like FZ150 score with entertainment marketing and are difficult to obtain in the DACH region. COLOURLOCK comes with Reach compliance, German production in Unna, and a heritage of three decades in the leather restoration business. Premium mid-range, not a hype segment.\u003c\/p\u003e\n\n\u003cp\u003eIf-then logic for the assortment: If you clean sneakers every month and need large quantities, you'll find the Pol-Star concentrate in liters more economical. If you want a coordinated complete set with brush, sponge, and cloths in a box and value the specific leather restoration formula with suede approval, then the Sneaker Cleaner Set is right for you. Both products come from the same company. The choice is not better or worse, but concentrate workflow or ready-to-use set.\u003c\/p\u003e\n\n\u003cp\u003eThe one tip that neither manufacturers nor shoe hype channels give: never dry your sneakers after cleaning with the printed inside of a newspaper. The black printer's ink migrates into damp white leather, and you have exactly the discoloration you just cleaned against. If you don't have cedar shoe trees at home, use unprinted white paper towels, loosely crumpled. Just as absorbent, shape-retaining, and without migration risk.\u003c\/p\u003e","brand":"Koch-Chemie × COLOURLOCK","offers":[{"title":"set","offer_id":57637092524367,"sku":"D1-KCX-8812-S-01","price":28.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/8812-S-01_1.png?v=1778249509"},{"product_id":"koch-chemie-colourlock-complete-leather-repair-set","title":"COLOURLOCK \"Complete Leather Repair Kit\"","description":"\u003ch2 id=\"speakable-headline\"\u003eLeather Repair Complete Set for Tears, Seat Bolsters, and Steering Wheels in One Box\u003c\/h2\u003e\n\n\u003cblockquote id=\"speakable-summary\"\u003e\n  \u003cp\u003e\u003cem\u003eWhat is the COLOURLOCK Complete Leather Repair Set?

Instead of having the entire upholstery re-covered by an upholsterer, you rebuild substance and color layer by layer.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eA re-upholstery by an upholsterer costs many times more than the set.\u003c\/strong\u003e The complete set addresses steering wheels, seat bolsters, gear knobs, and worn-out cover surfaces in one workflow. When preparing a used car, the investment pays for itself with the first sale, because the steering wheel in the listing image is the first impression for the buyer.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlexible liquid leather and water-based leather dye in one system.\u003c\/strong\u003e The liquid leather remains permanently elastic after curing and follows every movement of the seat bolster, instead of breaking open again at the first entry. The Leather Fresh leather dye dries to an abrasion-resistant, pigmented film that bonds with the leather pores when blow-dried warm. Result: your repair feels like original leather.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSix coordinated steps from cleaning to conditioning.\u003c\/strong\u003e Cleaner Mild gently opens the pores, the degreaser frees the surface from skin oils, the liquid leather fills tears flush, the Leather Fresh leather dye applies the tint in thin layers, the Leather Shield sealant repels jean dye transfer and friction, and the Leather Protector with medical care oil conditions older leather against drying out.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003ePractical tip from Detailing1:\u003c\/strong\u003e From our experience, we see the same mistake again and again — the fresh tint peels off after a few weeks because the degreasing step was skipped or performed too briefly. The simple rule: after Cleaner Mild, always follow up with the degreaser and rub the top coat until the surface appears visibly dull and is slightly sticky to the touch. Only this dissolution ensures that the new paint layer adheres. Otherwise, skin oils or residues of old leather care act like a release film and block the bonding — even on a visually clean steering wheel. Those who save time here will pay for it twice when reworking.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eFrom Tears to a Controlled Restored Seat in Six Steps\u003c\/h3\u003e\n\n\u003cp\u003eRestoration with the set follows a fixed six-step process that is non-negotiable in this order. Skipping a step risks a peeling tint, chipped areas, or a cloudy finish.\u003c\/p\u003e\n\n\u003cp\u003eStep 1: \u003cstrong\u003eFoam cleaning with Cleaner Mild.\u003c\/strong\u003e Fill the foam dispenser, apply foam with a leather brush or sponge, and work in seam-to-seam movements for 30 to 60 seconds. Remove with a damp viscose cloth. Never use abrasive microfiber cloths from paint preparation — they scratch the protective top coat layer of the leather.\u003c\/p\u003e\n\n\u003cp\u003eStep 2: \u003cstrong\u003eMechanical preparation and degreasing.\u003c\/strong\u003e Rub the dissolving degreaser on a lint-free cloth until the surface becomes dull and sticky to the touch. For heavily used steering wheels with ingrained hand grease residues, this can take five to ten minutes. Never use brake cleaner as a cheap alternative — it leaches the natural leather material and makes it brittle. Gently break rough edges or protruding fibers with the enclosed sanding pad, vacuum up sanding dust.\u003c\/p\u003e\n\n\u003cp\u003eStep 3: \u003cstrong\u003eStructural repair with liquid leather.\u003c\/strong\u003e Deeper tears and cracks are filled flush with the tinted filler. For through holes, reinforce the supplied repair fabric with leather glue to create a load-bearing base. Allow to dry completely.\u003c\/p\u003e\n\n\u003cp\u003eStep 4: \u003cstrong\u003eTinting with Leather Fresh leather dye.\u003c\/strong\u003e Shake the bottle vigorously, apply the dye to the applicator sponge, and apply in dabbing motions — never brush. Brushing immediately creates visible streaks because the water-based paint dries within seconds. After each thin layer, dry with a hot air dryer on a moderate setting until the water has evaporated. Two to four thin layers are sufficient for full coverage.\u003c\/p\u003e\n\n\u003cp\u003eStep 5: \u003cstrong\u003eSealing with Leather Shield.\u003c\/strong\u003e After at least 24 hours of curing time, ideally the next day. Apply friction-free and sparingly with a soft cloth — the sealant lays down a protective sacrificial layer that absorbs jean dye transfer and daily friction before it reaches the fresh tint.\u003c\/p\u003e\n\n\u003cp\u003eStep 6: \u003cstrong\u003eConditioning with Leather Protector.\u003c\/strong\u003e For older leather and convertible seats, work in the care product with medical care oil — it penetrates the fibers, slows down drying out, and protects against fading of the fresh pigments with built-in UV filters and antioxidants. The professional recommendation from the \u003ca href=\"\/collections\/lederpflege\"\u003eleather care range\u003c\/a\u003e: rather one thin layer more than one thick one.\u003c\/p\u003e\n\n\u003ch3\u003eAniline, Alcantara, and Bycast are Excluded\u003c\/h3\u003e\n\n\u003cp\u003eThe set is chemically precisely calibrated for pigmented smooth leather with a clear top coat layer. Applying it to incompatible material can ruin a seat cushion in one minute, which costs a lot of money to re-cover. Four strict limits to check before any repair.\u003c\/p\u003e\n\n\u003cp\u003eFirst limit: \u003cstrong\u003eAniline leather, semi-aniline, nubuck, and open-pored suede.\u003c\/strong\u003e These types of leather do not have a factory top coat — the open pores absorb cleaner and leather dye like a sponge, stick together, and become irreversibly stained. If pigmented smooth leather with a closed surface → Complete Leather Repair Set. If open-pored aniline or nubuck leather → \u003ca href=\"\/products\/koch-chemie-colourlock-aniline-nubuck-cleaner-lederreiniger\"\u003eCOLOURLOCK Aniline \u0026amp; Nubuck Cleaner\u003c\/a\u003e as a specialized alternative from the same manufacturer line.\u003c\/p\u003e\n\n\u003cp\u003eSecond limit: \u003cstrong\u003eAlcantara and microfiber fabrics.\u003c\/strong\u003e The binders in the leather dye and the synthetic fats in the Leather Protector permanently bond the fine fiber tips. Alcantara loses its typical suede feel and becomes dull. Third limit: \u003cstrong\u003eplastic-coated split leather.\u003c\/strong\u003e On these synthetic coatings, the leather fat is not absorbed and remains as a sticky film on the surface. Fourth limit: \u003cstrong\u003eworn-out material without a load-bearing fiber structure.\u003c\/strong\u003e In the case of deeply torn seat bolsters without a stable inner core, a combination of liquid leather and tint will sooner or later break open again — then the only way is to an upholsterer.\u003c\/p\u003e\n\n\u003cp\u003eIn the GTÜ test, the Smooth Leather Care Set Mild received a rating of 1.8 and was the only one of the twelve tested products to achieve the maximum score in the application category. For frequent driver steering wheels or sports seat bolsters, the tint will still wear off again after 12 to 24 months — this is a physical limitation of a water-based paint without additional hardener, not an application error. An honest ordering hurdle: if the remaining leather is heavily faded by UV, the factory color code no longer exactly matches the actual seat color — then sending a physical leather sample is mandatory for a color-identical mix.\u003c\/p\u003e\n\n\u003ch3\u003eFor Detailers, Upholsterers, and Ambitious Restoration Professionals\u003c\/h3\u003e\n\n\u003cp\u003eThe Repair Set is intended for workshops, used car detailers, upholsterer toolboxes, and ambitious classic and youngtimer owners who want to repeat repair and tinting in a calculable workflow. For the selective weekend care of new leather, it is oversized.\u003c\/p\u003e\n\n\u003cp\u003eDetailing businesses calculate economically: a worn steering wheel noticeably lowers the perceived value of a vehicle in an advertisement. The smart repair treatment with the set takes 60 to 90 minutes of active time plus drying breaks. Classic and youngtimer owners appreciate the Leather Protector with medical care oil for patina preservation — it is acid-free and is also used in museum conservation.\u003c\/p\u003e\n\n\u003cp\u003eHowever, if only color refreshment without structural repair is needed, the \u003ca href=\"\/products\/koch-chemie-colourlock-complete-colour-set\"\u003eCOLOURLOCK Complete Colour Set\u003c\/a\u003e is more cost-effective per vehicle, because liquid leather is not included but complementary sealants are. The simple if-then logic: Repair Set for combined structural damage plus tinting, Color Set for pure color smart repairs on multiple seats.\u003c\/p\u003e\n\n\u003cp\u003eA second truth that professional detailers know: successful restoration is 80 percent preparation and 20 percent tinting. Those who thoroughly complete the degreasing phase and build up the tint in thin layers with blow-drying achieve a result that is convincing even in daylight. Those who are sloppy or apply too thickly will see streaks at the first ray of sunshine and will have to rework for the next few hours.\u003c\/p\u003e\n\n\u003cp\u003eThe insider trick from detailing practice, which the official instructions do not formulate so clearly: liquid leather can hardly be sanded without flattening the leather pores. Professionals use a solvent-based GLD pen instead of sanding grit — it minimally re-dissolves the surface of the dried liquid leather and creates invisible transitions to the old leather. For heavily structured areas, fine sandpaper with a grit of 1000 additionally replaces the rigid sanding pad to preserve the original grain. Combined with blow-drying between each individual tinting layer, this is the difference between a six-month restoration and one that lasts two years on the entry bolster.\u003c\/p\u003e","brand":"Koch-Chemie × COLOURLOCK","offers":[{"title":"set","offer_id":57637092753743,"sku":"D1-KCX-8814-S-01-F034","price":208.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-colourlock-complete-leather-repair-set.png?v=1778657623"},{"product_id":"koch-chemie-colourlock-leather-fresh-set-xs","title":"COLOURLOCK \"Leather Fresh Set XS\"","description":"\u003ch2 id=\"speakable-headline\"\u003eLeather Dye for Cars for a Steering Wheel with the COLOURLOCK Leather Fresh Set XS\u003c\/h2\u003e\n\n\u003cblockquote id=\"speakable-summary\"\u003e\n  \u003cp\u003e\u003cem\u003eWhat is the COLOURLOCK Leather Fresh Set XS?

It contains 100 ml of tint in the factory color F034 Black, a fine-pored application sponge, and two nitrile gloves. The material kit is sufficient for a complete steering wheel or two heavily worn seat bolsters in the same vehicle. The core is a water-based polyurethane dispersion: lightfast pigments and flexible binders cross-link upon drying under hot air to form a semi-matte, abrasion-resistant polymer film on the factory surface of the leather.

Degreasing is done by eye, and weeks later the tint on the steering wheel peels off in thin films. The professional rule is the adhesive tape test: after cleaning with cleaning benzine or degreaser, press a short piece of painter's tape onto the spot and slowly pull it off. If the tape comes off easily, there is still skin oil or old care product on the surface, and the next tint layer would not adhere. If the tape sticks firmly, the surface is ready. No datasheet prescribes this test. From our experience, it is the insurance against the most frequent complaint in leather dyeing. With a 100 ml set, which is just enough for a steering wheel, a failed first layer is particularly expensive.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eFive-Step Workflow for Steering Wheel and Seat Bolster\u003c\/h3\u003e\n\n\u003cp\u003eLeather Fresh is step four in a fixed five-step plan. If you break the order or skip a step, you risk peeling within a few weeks. These steps have been the standard in reconditioning for decades and apply to the XS formulation exactly as they do to the professional container.\u003c\/p\u003e\n\n\u003cp\u003eStep 1: \u003cstrong\u003eDeep Cleaning.\u003c\/strong\u003e The damaged area is cleaned with \u003ca href=\"\/products\/koch-chemie-colourlock-leather-cleaner-mild-lederreiniger\"\u003eCOLOURLOCK Leather Cleaner Mild\u003c\/a\u003e or, for greasy smooth leather, with Leather Cleaner Strong. Work the foam in with a soft leather brush for 30 to 60 seconds, wipe off with a damp viscose cloth, and let dry. Never use abrasive microfiber cloths meant for paint care. They scratch the factory protective layer to which Leather Fresh must later adhere.\u003c\/p\u003e\n\n\u003cp\u003eStep 2: \u003cstrong\u003eDegreasing.\u003c\/strong\u003e Wipe with COLOURLOCK Leather Cleaning Benzine or the solvent-free Degreaser on a lint-free cloth until the surface becomes visibly dull. Hand grease on the steering wheel, old leather care on the seat bolster, or surfactant residues from the cleaner will otherwise prevent the adhesion of the water-based tint. Use the adhesive tape test as a check. Step 3: \u003cstrong\u003eMechanical Smoothing.\u003c\/strong\u003e Gently level raised microfibers on the worn area with the COLOURLOCK Leather Sanding Pad, using light circular motions without pressure. Remove sanding dust with a cloth lightly moistened with benzine. Fill deep cracks or torn seat bolsters now with \u003ca href=\"\/products\/koch-chemie-colourlock-fluid-leather-lederfarbe-fuer-reparaturen\"\u003eFluid Leather\u003c\/a\u003e as a filler. Leather Fresh itself has no filling effect.\u003c\/p\u003e\n\n\u003cp\u003eStep 4: \u003cstrong\u003eTinting with Leather Fresh.\u003c\/strong\u003e Shake extremely well before use until pigments and binders are homogeneous. Apply the color to the enclosed sponge, never directly to the leather. Dab or apply in light circular motions in very thin layers from seam to seam, and immediately cure each layer with a household hairdryer on a medium setting from about 20 cm distance for 60 to 90 seconds. Only the heat evaporates the water and cross-links the polymer. High opacity is achieved through three to five very thin repetitions, not by a thick layer. Forcing full opacity in one go leads to blistering and the dreaded rubbing off upon the first touch. Step 5: \u003cstrong\u003eSealing.\u003c\/strong\u003e The tinted area must rest and outgas for 24 hours. Only then gently apply Leather Shield as friction protection or Leather Protector with UV protection and antioxidants, without strong pressure and without rubbing. Otherwise, fresh polymer layers will detach again.\u003c\/p\u003e\n\n\u003ch3\u003eAniline Leather, Deep Cracks, and Wrong Solvents as Hard Limits\u003c\/h3\u003e\n\n\u003cp\u003eLeather Fresh is chemically highly calibrated for semi-matte, surface-dyed smooth leather with a functioning protective layer. If the product is applied to incompatible substrates or if the wrong chemicals are used during pre-treatment, a leather interior that quickly costs four figures to re-upholster can be ruined in minutes. Three limits that must be checked before each application.\u003c\/p\u003e\n\n\u003cp\u003eFirst limit: \u003cstrong\u003eAniline leather, nubuck, and open-pore suede.\u003c\/strong\u003e These types of leather do not have a factory protective layer. The aqueous polymer dispersion penetrates uncontrollably into the open pores and coats the surface in a patchy and greasy manner. Before each application, perform the water drop test: place a drop on an inconspicuous area. If it is absorbed within 30 seconds and remains dark, the leather is open-pored, and the set is not suitable. For aniline leather, the \u003ca href=\"\/products\/koch-chemie-colourlock-aniline-nubuck-cleaner-lederreiniger\"\u003eCOLOURLOCK Aniline and Nubuck Cleaner\u003c\/a\u003e is the correct choice. However, for pigmented smooth leather with a clear protective layer or for PU synthetic leather in the interior, you are on the right track.\u003c\/p\u003e\n\n\u003cp\u003eSecond limit: \u003cstrong\u003eDeep cracks and torn seat bolsters.\u003c\/strong\u003e Leather Fresh conceals superficial scratches and colors worn areas excellently, but it does not bridge gaps. Testers in vehicle detailing forums rate exactly this point as the hardest limitation. For cracks or already torn seat bolsters, Fluid Leather as a filler is a mandatory preceding step. Third limit: \u003cstrong\u003eAggressive brake cleaners for degreasing.\u003c\/strong\u003e If, out of frugality, brake cleaner is used instead of cleaning benzine or degreaser, the factory protective layer is immediately destroyed by acetone and naphtha components, making the leather brittle. This mistake is regularly documented in DIY forums. It is irreparable.\u003c\/p\u003e\n\n\u003cp\u003eA fourth honest limitation, which marketing is reluctant to state: F034 Black usually covers in the first pass. Light shades like beige, white, or cream colors, based on experience from professional reconditioning, require five to six layers until dark scuff marks on the steering wheel are completely concealed. If you want to restore a light interior, calculate double the working time and, if in doubt, have a second XS set ready. Opened bottles can be used for six to twelve months, after which the dispersion thickens and becomes unusable for fine auto-leveling.\u003c\/p\u003e\n\n\u003ch3\u003eCar Leather Dye for Hobby Detailers and One-Time Repairs\u003c\/h3\u003e\n\n\u003cp\u003eThe XS set is the entry-level kit for exactly one application: punctual smart repair on a single vehicle. 100 ml is enough for a complete steering wheel or two heavily worn seat bolsters. Those who regularly recondition lease returns or an entire fleet should switch directly to the professional container from the \u003ca href=\"\/collections\/lederpflege\"\u003eleather care\u003c\/a\u003e collection.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHobby detailers and car enthusiasts\u003c\/strong\u003e are the main target group. People who want to eliminate the worn greasy sheen on the steering wheel after 80,000 to 150,000 kilometers without paying for a professional re-upholstery. A steering wheel re-upholstery in the DACH region can quickly cost several hundred euros gross, while the XS set, when applied correctly, achieves a visually and haptically indistinguishable result at a fraction of the cost. For used car sellers, this is the difference between selling with or without visible wear-related depreciation.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eClassic car owners\u003c\/strong\u003e use the set to preserve the patina of 30-year-old leather and gently touch up small imperfections without destroying the historical value through complete re-upholstery. \u003cstrong\u003eFirst-time users before a larger restoration\u003c\/strong\u003e test the technique with the XS volume on a single spot before switching to the professional container. Compared to competing systems, COLOURLOCK scores at the beginner level with its user-friendly auto-leveling viscosity and OEM color database. Geist Easy Colour Restorer advertises self-cross-linking without sealing, but in the 50 ml format, it is more expensive per application and lacks the official factory color code library. Aerosol sprays like Volico or Motip work with solvent-based spray mist and require extensive masking of the interior. For the typical localized damage on the steering wheel, the sponge application of the XS set is more respiratory-friendly and more controllable in a cramped interior.\u003c\/p\u003e\n\n\u003cp\u003eFrom our experience, the crucial leverage for first-time users is not the color accuracy of the tint, but the discipline in preparation. Those who meticulously follow steps one to three will achieve a steering wheel result at a professional upholsterer's level with the XS set. Those who degrease without doing the adhesive tape test will see the tint peel off after three weeks. The tint itself is not the risk.

Degreasing is completed by eye, and weeks later, the dye on the steering wheel peels off in thin films. The professional rule is the tape test: after cleaning with cleaning benzine or degreaser, press a short piece of masking tape onto the spot and slowly pull it off. If the tape comes off easily, there is still skin oil or old care product on the surface, and the next layer of dye would not adhere. If the tape sticks firmly, the surface is ready. No data sheet prescribes this test. In our experience, it is the insurance against the most common complaint in the industry.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eFive-Step Workflow for Large-Area Restoration\u003c\/h3\u003e\n\n\u003cp\u003eLeather Fresh is step four in a fixed five-step plan. Breaking the sequence or skipping a step risks peeling within weeks. These steps have been the standard for detailing for decades.\u003c\/p\u003e\n\n\u003cp\u003eStep 1: \u003cstrong\u003eDeep Cleaning.\u003c\/strong\u003e The leather interior is cleaned with \u003ca href=\"\/products\/koch-chemie-colourlock-leather-cleaner-mild-lederreiniger\"\u003eCOLOURLOCK Leather Cleaner Mild\u003c\/a\u003e or, for heavily soiled or greasy smooth leather, with Leather Cleaner Strong. Work the foam in with a soft leather brush for 30 to 60 seconds, wipe off with a damp viscose cloth, and let dry. Never use abrasive microfiber cloths designed for paint care. They scratch the factory protective layer that the Leather Fresh must later adhere to.\u003c\/p\u003e\n\n\u003cp\u003eStep 2: \u003cstrong\u003eDegreasing.\u003c\/strong\u003e Wipe with COLOURLOCK Leather Cleaning Benzine or the solvent-free Degreaser on a lint-free cloth until the surface becomes visibly dull. Hand grease on the steering wheel, old leather care products on the seat bolsters, or surfactant residues from the cleaner will otherwise prevent adhesion. Use the tape test for verification. Step 3: \u003cstrong\u003eMechanical Smoothing.\u003c\/strong\u003e Gently level raised microfibers on worn seat bolsters with the COLOURLOCK Leather Sanding Pad, using light circular motions without pressure. Remove sanding dust with a cloth lightly dampened with cleaning benzine. Fill deep cracks now with \u003ca href=\"\/products\/koch-chemie-colourlock-fluid-leather-lederfarbe-fuer-reparaturen\"\u003eFluid Leather\u003c\/a\u003e as a filler. Leather Fresh itself does not fill.\u003c\/p\u003e\n\n\u003cp\u003eStep 4: \u003cstrong\u003eDyeing with Leather Fresh.\u003c\/strong\u003e Shake extremely well before use to ensure pigments and binders are homogeneous. Always transfer from the 1-liter container into a smaller 100-ml dispensing bottle or a paint dish. Dabbing directly from the heavy canister with a sponge is difficult to control in a real interior and spills in two out of ten cases. Dab or apply in circular motions in very thin layers from seam to seam, immediately cross-linking each layer with a heat gun. This evaporates the water and cross-links the polymer. High opacity is achieved by repeated application, not by a thick single layer. For large areas like entire seat benches in professional operations, Leather Fresh is alternatively applied with an airbrush gun. The atomized application prevents the micro-streaks that a sponge inevitably leaves with flat application. Step 5: \u003cstrong\u003eSealing.\u003c\/strong\u003e The dyed surface must rest and outgas for 24 hours before applying Leather Shield sealant or Leather Protector without strong pressure or rubbing.\u003c\/p\u003e\n\n\u003ch3\u003eAniline Leather, Deep Cracks, and Wrong Solvents as Hard Limits\u003c\/h3\u003e\n\n\u003cp\u003eLeather Fresh is chemically highly calibrated for semi-gloss, surface-dyed smooth leather with a functional protective layer. Anyone who applies the product to incompatible substrates or uses the wrong chemical during pre-treatment risks ruining a leather interior that would cost five figures to replace. Three limits that must be checked before each application.\u003c\/p\u003e\n\n\u003cp\u003eFirst limit: \u003cstrong\u003eAniline leather, nubuck, and open-pored suede.\u003c\/strong\u003e These types of leather do not have a factory protective layer. The aqueous polymer dispersion penetrates uncontrollably into the open pores and coats the surface unevenly and greasy. Before each application, perform the water drop test: place a drop on an inconspicuous area. If it is absorbed within 30 seconds, the leather is open-pored, and the set is taboo. However, if you have pigmented smooth leather with a clear protective layer or PU artificial leather in the interior, this product is suitable. An exception: aniline leather may be dyed with Leather Fresh if the entire component is completely recolored. Local repairs will still fail.\u003c\/p\u003e\n\n\u003cp\u003eSecond limit: \u003cstrong\u003eDeep cracks and broken seat bolsters.\u003c\/strong\u003e Leather Fresh conceals superficial scratches and excellently dyes worn areas, but it does not bridge gaps. Testers in vehicle care forums rate this very point as the hardest limitation. For cracks or already broken seat bolsters, Fluid Leather as a filler is a mandatory predecessor, supplemented in extreme cases by COLOURLOCK Neutral Binder to stabilize the fiber. Third limit: \u003cstrong\u003eAggressive brake cleaner for degreasing.\u003c\/strong\u003e Anyone who uses brake cleaner instead of cleaning benzine or degreaser out of a reflex to save money will immediately destroy the factory protective layer with acetone and naphtha components, making the leather brittle and cracked. This error is regularly documented in mechanic forums. It is irreparable; the leather is scrap after this treatment.\u003c\/p\u003e\n\n\u003cp\u003eAnd the fourth honest limit, which marketing doesn't like to formulate: F034 Black covers in the first pass. Light shades like beige, white, or cream colors require five to six layers, based on practical experience from detailers, until dark scuff marks on the steering wheel or seat edges are completely concealed. If you are restoring a beige interior, double the working time per vehicle. On shiny bicast leathers that become sticky due to skin oil decomposition, Leather Fresh also does not save the structure. Here, only the color loss can be temporarily covered; the polymer film physically disintegrates.\u003c\/p\u003e\n\n\u003ch3\u003eCar Leather Dye in Professional Volume for Upholsterers and Fleet Detailers\u003c\/h3\u003e\n\n\u003cp\u003eThe Set XL is not a hobby product for Sunday repairs of a single seat bolster. Anyone who wants to restore a single steering wheel or a small damaged area on a private car should more sensibly choose the 150-ml format from the \u003ca href=\"\/collections\/lederpflege\"\u003eleather care\u003c\/a\u003e collection with Set XS. The large 1-liter container defines a different target group and a different scale of application.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCommercial vehicle detailers and smart repair shops\u003c\/strong\u003e are the primary target group. Leased vehicles returning with worn steering wheels and scuffed seat bolsters are re-dyed black with standard F034 dye in the detailing hub, because factory black is the most common OEM color in the German premium fleet. A 1-liter set covers six to ten of these detailing jobs. The business can work without delivery interruptions.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSaddle makers and furniture restorers\u003c\/strong\u003e use the large container for components where a new cover would destroy the originality certificate, or for furniture upholstery with large restoration areas. The 46-color logic allows invisible touch-ups right on a seat surface. If the dye is precisely matched to the OEM color, a smart repair on the seat upholstery looks like factory condition. \u003cstrong\u003eFleet managers and car dealerships\u003c\/strong\u003e with standard black or carbon black leather interiors benefit from continuous inventory maintenance. A 1-liter stock is computationally more sensible than 30 to 50 individual bottles.\u003c\/p\u003e\n\n\u003cp\u003eCompared to competing systems, the Set XL is the volume-oriented answer. Geist. Easy Colour Restorer markets a 50-ml format with self-crosslinking for DIY users but cannot deliver a 1-liter professional container. Ledermax Repair #6.0, as a 2K system with a hybrid hardener, is chemically more complex and, due to its pot life of one to two hours, less flexible for quick smart repair jobs. Swissvax Leather Healer positions itself in luxury detailing at significantly higher costs per milliliter. COLOURLOCK wins at the professional level through scalability and a complete workflow ecosystem consisting of Leather Cleaner Mild and Strong, Cleaning Benzine or Degreaser, Leather Sanding Pad, Fluid Leather, Leather Fresh, and sealing with Leather Shield or Protector. Every link in the chain is coordinated with the next. Those who also maintain the exterior during interior restoration can sensibly supplement the set with the \u003ca href=\"\/collections\/innenraumreiniger\"\u003einterior cleaner\u003c\/a\u003e assortment for the cockpit, headliner, and door panels.
