The pre-cleaner gets sprayed onto dry paint that's been baking in the sun and dries on before you can rinse it. What's left are streaks and edges, and with acidic products on aluminium wheels even dull spots that only polishing will fix. Flood the car with clean water first, work in the shade on a cool surface and spray from the bottom up so runs don't cut clean tracks through the dirt. Then rinse from the top down. We regularly see exactly this one step, the pre-rinse, skipped to save time – and it costs you the whole pass.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eA pre-cleaner removes the dirt that would otherwise scratch\u003c\/h3\u003e\n\n\u003cp\u003eThe pre-cleaner takes off the hard part of the dirt before any fabric touches the paint for the first time. Whatever runs off here can't grind later.\u003c\/p\u003e\n\n\u003cp\u003eRoad dust isn't powder, it's a mineral mix with a high quartz content. Quartz is more than twice as hard as cured clear coat. Put simply: every speck of dust on the bonnet is a piece of grit. Day to day that means the trick isn't wiping extra gently, it's leaving as little as possible to wipe in the first place.\u003c\/p\u003e\n\n\u003cp\u003eThat's why swirls rarely come from the wash mitt itself. They come from whatever it drags across the panel. A car that goes under the mitt without a rinse picks up a fine web of scratches with every wash, and it only shows months later as a fan pattern when low sun rakes across the paint.\u003c\/p\u003e\n\n\u003cp\u003eSpecifically, the pre-cleaner tackles four groups of dirt: traffic film made of dust, tyre wear and oil mist; dried bug remains on the front, mirrors and mirror bases; the brake-dust haze on the lower doors; and in winter, loose salt crust. The rest – that last wafer-thin greasy film – is deliberately left to the shampoo.\u003c\/p\u003e\n\n\u003cp\u003eThat also marks the limit. A pre-cleaner doesn't replace the wash, and if you run a finger over the paint after rinsing you'll still feel drag. We get plenty of questions on exactly this point, usually hoping to skip contact altogether. Prepping touchless and then washing with minimal contact remains the realistic goal.\u003c\/p\u003e\n\n\u003cp\u003eA pre-cleaner differs from a foam wash in its role, not in how it works. Foam is just a carrier that keeps the chemistry on vertical panels for longer. What you put in the lance decides the effect. How the two steps fit together is covered in \u003ca href=\"\/collections\/snow-foam\"\u003eSnow Foam\u003c\/a\u003e and in the overview of \u003ca href=\"\/collections\/autowasche\"\u003ecar washing\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eAlkaline against grease, acidic against minerals\u003c\/h3\u003e\n\n\u003cp\u003eThe most important number on a pre-cleaner is rarely printed big on the label. It's the pH, and it decides which dirt the product can even attack.\u003c\/p\u003e\n\n\u003cp\u003eAlkaline pre-cleaners work at around pH 11 to 13. Alkalis saponify fats, making them water-soluble by breaking the long fat molecules into soap-like fragments. In practice you notice it when the grey oil-mist haze around the wheel arches is simply gone after rinsing, without you touching it. \u003ca href=\"\/products\/sonax-profiline-multiclean-alkaline-vorreiniger\"\u003eSONAX PROFILINE MultiClean „Alkaline\" Pre-Cleaner\u003c\/a\u003e is typical of this type.\u003c\/p\u003e\n\n\u003cp\u003eAcidic pre-cleaners sit at the other end, usually between pH 1 and 3. Acids dissolve anything mineral: limescale from hard tap water, cement haze from building sites and dried-in water spots. \u003ca href=\"\/products\/sonax-profiline-multiclean-acid-kraftreiniger-sauer\"\u003eSONAX PROFILINE MultiClean „Acid\" Heavy-Duty Cleaner (Acidic)\u003c\/a\u003e is the counterpart, and for spot limescale on glass and paint you reach for \u003ca href=\"\/products\/gyeon-q2m-waterspot-kalkfleckenentferner\"\u003eGYEON Q²M WaterSpot Limescale Remover\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003cp\u003eIn between sit two specialists that don't fit neatly into either group. Iron removers like \u003ca href=\"\/products\/gyeon-q2m-iron-redefined-flugrostentferner\"\u003eGYEON Q²M Iron (REDEFINED) Iron Remover\u003c\/a\u003e bind embedded brake dust into water-soluble complexes and show it by bleeding purple. So you watch live where the fallout sits, no guesswork needed.\u003c\/p\u003e\n\n\u003cp\u003eTar and tree sap don't react to either route, because they're neither greasy nor mineral but resinous. For those you need a solvent-based product like \u003ca href=\"\/products\/gyeon-q2m-tar-redefined-harzentferner-teerentferner\"\u003eGYEON Q²M Tar (REDEFINED) Resin \u0026amp; Tar Remover\u003c\/a\u003e, which softens the resin structure rather than breaking it apart. Use it on spots, never across the whole car.\u003c\/p\u003e\n\n\u003cp\u003eOne rule applies across all types: never acidic and alkaline on the same wet surface at the same time. They neutralise each other, and you end up with salt and water instead of cleaning power. Between two different products there's always a full rinse with clean water.\u003c\/p\u003e\n\n\u003ch3\u003eDwell time is the real active ingredient\u003c\/h3\u003e\n\n\u003cp\u003eChemistry needs time. The most common reason for a disappointing result isn't the wrong product, it's a thirty-second dwell.\u003c\/p\u003e\n\n\u003cp\u003eA pre-cleaner has to creep under the dirt film before it can lift it. The surfactants migrate to the boundary between paint and dirt and undermine the bond, and that happens by diffusion. You can't speed diffusion up by laying down more product. It simply takes minutes. Three to five is the usual window.\u003c\/p\u003e\n\n\u003cp\u003eToo short means half the effect. Too long means it dries on, and a pre-cleaner that dries on is worse than none at all, because the loosened dirt bakes back on and the concentration climbs as it evaporates. So only spray as much area as you can rinse off again within the dwell time. In the heat that means one side of the car, not the whole thing.\u003c\/p\u003e\n\n\u003cp\u003eTemperature cuts both ways. Warm paint speeds up the reaction, and it speeds up evaporation just as much. What can sit for five minutes in the cool of the morning is dry after two in the afternoon. A cool surface and shade aren't a comfort thing, they're part of the dosing.\u003c\/p\u003e\n\n\u003cp\u003eDilution is the second lever. With \u003ca href=\"\/products\/koch-chemie-prewash-express-pe-vorreiniger\"\u003eKoch-Chemie PreWash express „Pe\" Pre-wash\u003c\/a\u003e and \u003ca href=\"\/products\/koch-chemie-pre-foam-efficient-pfe-vorreiniger-insektenloeser\"\u003eKoch-Chemie Pre-Foam efficient „Pfe\" Pre-Cleaner \u0026amp; Insect Remover\u003c\/a\u003e, the mix controls how strong the pass is. What we see day-to-day: a second mild pass almost always beats one highly concentrated pass, because round two works on dirt that's already loosened.\u003c\/p\u003e\n\n\u003cp\u003eAnd to set expectations: the first time, a mid-size car will take you about twenty minutes, just because pre-rinsing, spraying and rinsing in sections feels unfamiliar. By the third pass you're down to ten. The difference is routine, not skill.\u003c\/p\u003e\n\n\u003ch3\u003eStart wet and never let it dry on\u003c\/h3\u003e\n\n\u003cp\u003eThe process is short, and the order is non-negotiable. Every step exists because something goes wrong without it.\u003c\/p\u003e\n\n\u003cp\u003eFirst, flood the dry car completely with clean water. That takes the loose sand with it that would otherwise sit in the foam later, and it cools the surface. Wet paint also dilutes the incoming cleaner evenly, instead of letting it stand concentrated in spots.\u003c\/p\u003e\n\n\u003cp\u003eThen apply from the bottom up. The reason is subtle and the effect immediate: if the cleaner runs down over still-dirty paint, it cuts clean streaks that dwell for different times when you spray again and stay visible as shadows. Working from the bottom, it runs over surface that's already wetted.\u003c\/p\u003e\n\n\u003cp\u003eFoam lance, pressure sprayer and a simple pump sprayer all do the job. The lance gives you the biggest advantage on vertical panels, because the foam clings there instead of sliding off in seconds. \u003ca href=\"\/products\/gyeon-q2m-foam-schaumreiniger\"\u003eGYEON Q²M Foam Snow Foam\u003c\/a\u003e is built for that, and \u003ca href=\"\/products\/gyeon-q2m-apc-allzweckreiniger\"\u003eGYEON Q²M APC All-Purpose Cleaner\u003c\/a\u003e also covers door shuts, wheel arches and floor mats.\u003c\/p\u003e\n\n\u003cp\u003eRinse from the top down, keeping your distance at a flat angle. A pressure jet held too close drives water behind trim and seals, where it sits for days and trickles back out on the next sunny day. Bare and anodised aluminium parts are sensitive too – never let alkaline cleaners dry on them.\u003c\/p\u003e\n\n\u003cp\u003eAfter rinsing, go straight into the two-bucket hand wash or add a foam pass as a buffer. Which \u003ca href=\"\/collections\/autoshampoo\"\u003eCar shampoo\u003c\/a\u003e goes in the bucket depends on whether your paint is sealed. For boats and motorhomes the same system exists as a separate marine line with alkaline and acidic hull pre-cleaners.\u003c\/p\u003e\n\n\u003ch3\u003eKoch-Chemie and GYEON shape this range\u003c\/h3\u003e\n\n\u003cp\u003eTwo manufacturers make up the lion's share of this category, and they go about it very differently. The rest is split between SONAX, INNOVACAR and Soft99.\u003c\/p\u003e\n\n\u003cp\u003eKoch-Chemie thinks in concentrates and in jobs. \u003ca href=\"\/products\/koch-chemie-vorreiniger-b-vb-vorreiniger\"\u003eVorreiniger B „Vb\"\u003c\/a\u003e is the workhorse for everyday traffic film and our clear best-seller. \u003ca href=\"\/products\/koch-chemie-pre-wash-b-pb-vorreiniger\"\u003eKoch-Chemie Pre-Wash B „Pb\" Pre-Cleaner \u0026amp; Bug Remover\u003c\/a\u003e goes after insect protein, which simply needs a different attack than dust and oil.\u003c\/p\u003e\n\n\u003cp\u003eGYEON thinks in decontamination stages. The Q²M line is built like a modular kit where each product takes on exactly one type of contamination: iron, tar, limescale, general dirt, foam. If you want to keep clear which step fixes which problem, this is the tidiest structure in the range.\u003c\/p\u003e\n\n\u003cp\u003eWith PROFILINE MultiClean, SONAX covers the alkaline\/acidic pair and puts the pH logic right there on the shelf. Both versions are the same idea pointed in two directions, which makes the choice easy once you know what dirt you're facing.\u003c\/p\u003e\n\n\u003cp\u003eFor getting started without concentrate maths, there's \u003ca href=\"\/products\/innovacar-sp1-prewash-vorwaesche-autoshampoo\"\u003eINNOVACAR „SP1\" Prewash Pre-Wash Car Shampoo\u003c\/a\u003e. It deliberately sits between pre-wash and shampoo and is the pragmatic answer if you look after one car and don't want two jerry cans in the cupboard.\u003c\/p\u003e\n\n\u003cp\u003ePrep also includes the mechanical stage. Clay bar and clay sponge come after the chemistry and before polishing, when something is still sitting on the paint after rinsing that you can feel with a fingernail. Chemistry first, mechanics second – in that order the clear coat stays intact.\u003c\/p\u003e\n\n\u003ch3\u003eWhich pre-cleaner suits your car\u003c\/h3\u003e\n\n\u003cp\u003eThe choice comes down to three questions: how do you drive, how hard is your water, and what's sitting on your paint.\u003c\/p\u003e\n\n\u003cp\u003eFor a car in normal commuter use, washed every two weeks, a standard alkaline pre-cleaner is all you need. Traffic film is exactly what these products are built for, and nothing more is required. Reaching for the acidic heavy-duty cleaner here means buying a tool for a problem you don't have.\u003c\/p\u003e\n\n\u003cp\u003eLong summer drives shift the balance. Bug remains are proteins; after a few warm hours they're properly stuck and, if you go at them mechanically, they leave the front covered in fine scratches. A pre-cleaner geared towards bug removal is then the more important buy, and it's worth a look at \u003ca href=\"\/collections\/insektenentferner\"\u003eInsect remover\u003c\/a\u003e too.\u003c\/p\u003e\n\n\u003cp\u003eWith hard tap water or after a drive through roadworks, the acidic side takes priority. Limescale and cement haze don't react to any alkaline cleaner, however strong you mix it. What counts here is the right type, not the dose, and you keep application short and to the spot.\u003c\/p\u003e\n\n\u003cp\u003eIf your car wears a ceramic coating, go gentler. Strongly alkaline pre-cleaners at the top of the pH range shorten the coating's lifespan with every pass. Mix the concentrate weaker, keep the dwell short and rinse thoroughly. Whatever cleaning power you give up, the low-contact wash afterwards makes up for.\u003c\/p\u003e\n\n\u003cp\u003eAnd if you're just starting out: a ready-to-use or easy-to-mix product plus a pressure sprayer will see you through your first summer. The finer points – iron remover, tar remover, limescale remover – come later, the first time you notice something still left after rinsing.

Apply the pre-cleaner from the bottom up onto the cold, pre-wetted vehicle — that way you avoid run marks on unevenly dried panels. After 5 minutes dwell time at most (VDA Class A), rinse off thoroughly with the pressure washer.\u003c\/p\u003e\n\u003cp\u003eIn self-service wash bays, 1:300 is enough — that's the high-volume dilution and it cuts product use noticeably over a full year. For wheel cleaning you work at 1:3 to 1:10, sprayed straight onto the cold dry wheel, left to dwell for 1 minute at most, then rinsed. Important: don't use it on hot brake discs or warm wheels. The heat speeds up the reaction in an uncontrolled way and raises the risk of dulling on painted alloy wheels.\u003c\/p\u003e\n\u003cp\u003eFor wash tunnels with conveyor lines you typically run 1:100 to 1:200. Dwell time in the tunnel is usually 30 to 60 seconds, which still keeps you safely inside the VDA-B limit of 1 minute. The higher dilution cuts foam volume at the spray arch but keeps enough cleaning power thanks to the high active-ingredient concentration. With high vehicle throughput it pays to switch to the 225 kg container — a better price per litre of concentrate.\u003c\/p\u003e\n\u003cp\u003eFor copolymer de-waxing — stripping old preservatives before a fresh sealant — 1:5 to 1:10 is the right dilution.

No snow foam replacement.\u003c\/h3\u003e\n\u003cp\u003eThe Koch Chemie Vorreiniger B is not a mild foam pre-cleaner for coating-protected vehicles. pH 13.1 is workshop level — strong, uncompromising, but sensitive in use.\u003c\/p\u003e\n\u003cp\u003eIts strength is on heavily soiled vehicles with insect, bird-dropping and road residue after a long motorway run or after winter. It also works reliably on baked-on brake dust on steel wheels and on alkali-resistant painted alloy wheels. The foam is functional — not the show foam you get from classic snow-foam products, but a working foam that clings to vertical panels.\u003c\/p\u003e\n\u003cp\u003eNow the honest read on the limits. First, the Vorreiniger B is not friendly to active ceramic coatings. Used regularly on coating-protected vehicles it breaks the coating down faster than a pH-neutral pre-wash foam does. For vehicles with an active coating, the milder Pre-Foam efficient is the better call. Second, don't use it on polished aluminium or chrome surfaces — despite the corrosion inhibitors, pH 13.1 can dull untreated light metals. The inhibitors protect anodised alloy, not bare alloy.\u003c\/p\u003e\n\u003cp\u003eThird: it is not paint-surface gentle in the sense of a hand-wash chemistry. If you look after your new car with the two-bucket method and a mild car shampoo, you don't need a Vorreiniger B in the garage. Its job starts where hand washing no longer cuts it — on heavily soiled vehicles, commercial fleets, utility vehicles and construction machinery.\u003c\/p\u003e\n\u003cp\u003eProtective gear is a must, not optional. Nitrile gloves and safety glasses when mixing and applying. On skin contact, rinse straight away with plenty of water and remove residue with mild soap. Never leave the concentrate bottle open — the fumes from the alkaline cleaner irritate airways and mucous membranes on longer exposure. Close it well after use and store it frost-free and dark.\u003c\/p\u003e\n\u003cp\u003eThe material compatibility of the Vorreiniger B has clear limits. Allowed: steel, anodised aluminium, alkali-resistant painted surfaces, glass and standard automotive plastics. Not allowed: polished light metals, bare chrome surfaces, coloured anodised layers (risk of discolouration) and matt-painted surfaces without a protective film. When in doubt, test on an inconspicuous spot before the first application and watch it for 3 minutes — it costs little time and saves expensive damage.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-vorreiniger-b-vb-vorreiniger_ergebnis.jpg?v=1776199899\" alt=\"Koch-Chemie Vorreiniger B workshop-grade alkaline cleaner pH 13.1\" loading=\"lazy\" style=\"width:100%;height:auto;display:block;margin:1.5em 0;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eWho the Vorreiniger B is for — from the pro to the home garage\u003c\/h3\u003e\n\u003cp\u003eThe Koch Chemie Vorreiniger B is built for pros and experienced home users with know-how in alkaline chemistry.

The first time you mix it, work with a calibrated measuring jug — go by eye and most beginners land far too concentrated, which loads the material needlessly and encourages streaking.\u003c\/p\u003e\n\u003cp\u003eIf you want a mild, coating-friendly pre-wash foam, you're better off with the Pre-Foam efficient. If you supply express wash lines with extremely short dwell times, reach for the Pre-Wash B. If you need the strongest cleaner for baked-on oil and grease residue on engines and chassis, take the Copo Star BMP-T. The Vorreiniger B is the all-round middle of the \u003ca href=\"\/collections\/koch-chemie\"\u003eKoch-Chemie range\u003c\/a\u003e — phosphate-free, double VDA-compliant, fast-separating to ÖNORM 5106 and therefore also approved for biological process-water treatment systems.\u003c\/p\u003e\n\u003cp\u003eAnd that last point is the real Detailing1 insight.

That's exactly the thinking behind the \u003cstrong\u003eSONAX PROFILINE MultiClean Alkaline\u003c\/strong\u003e: a high-alkaline pre-cleaner that loosens bug splatter, organic road film, tar particles and heavy brake-dust deposits in the pre-wash, so the contact-wash risk to your paint drops noticeably during the shampoo pass that follows.

Let the cleaner dwell for 2–5 minutes without letting it dry on — in hot weather or direct sun, shorten the dwell time and keep the car damp. Then rinse thoroughly with the pressure washer before you go into the shampoo pass. For maximum bug removal, run the cleaner stronger across the front end (grille, bumper) and, if needed, work it briefly with a soft brush before you rinse.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eAlkaline car pre-cleaner — how the MultiClean Alkaline works chemically\u003c\/h3\u003e\n\u003cp\u003eMost of the organic dirt on a car — bug splatter, pollen, bird droppings, the fatty salts off road wear, oil film — is stable in the acidic-to-neutral pH range. A high-alkaline cleaner like the \u003cstrong\u003eSONAX PROFILINE MultiClean Alkaline\u003c\/strong\u003e shifts the chemical balance: esters and fatty compounds in organic grime are split apart by saponification under alkaline conditions, protein structures in bug residue are denatured and dissolved. The result isn't a mechanical lift-off but a chemical destabilisation of the dirt — the bond to the paint is weakened without you having to work the surface mechanically.\u003c\/p\u003e\n\u003cp\u003eOne thing to get right: high-alkaline pre-cleaners aren't \"do-it-all\" cleaners for every situation. They're tuned for organic, alkali-soluble grime. Mineral deposits like lime spots, water spots or embedded metal rust (brake dust as iron particles) barely react to an alkaline attack — that calls for acidic specialist cleaners. The MultiClean Alkaline makes sense in a two-wash concept: alkaline pre-wash first (organic grime), then a follow-up with an iron remover or acidic cleaner (mineral deposits). Combine both steps and you clean chemically all the way, instead of just looking clean.\u003c\/p\u003e\n\u003cp\u003eAlso important: alkaline pre-cleaners have to be rinsed off completely before you go into the shampoo wash — residue can react with some sealants or wax layers and knock back their bond for a while. A thorough pressure rinse after the dwell time is enough to clear the cleaner off fully. On freshly sealed cars (ceramic coating, paint sealant), only use it on genuinely heavily soiled spots and keep it out of the regular weekly wash, so you don't put unnecessary strain on the protection. For the routine wash of a sealed car, reach for a mild, pH-neutral shampoo as your standard wash product instead.\u003c\/p\u003e\n\n\u003ch3\u003eUsing a pre-wash like a pro — the application step by step\u003c\/h3\u003e\n\u003cp\u003eThe best way to use the \u003cstrong\u003eSONAX PROFILINE MultiClean Alkaline\u003c\/strong\u003e starts on a dry car. Moisture on the paint thins the cleaner straight away and cuts the working concentration before it ever had a chance to act. Recommended method: fill the cleaner neat or at a low dilution ratio (1:3 to 1:10 depending on how dirty it is) into a pump sprayer, a \u003ca href=\"\/products\/sonax-profiline-foamsprayer-schaumspruher\"\u003eSONAX PROFILINE FoamSprayer\u003c\/a\u003e or a foam cannon on the pressure washer, and spray it evenly across the whole car — bottom to top, so the cleaner runs down the bodywork and the lower, dirtier areas get properly wetted too.\u003c\/p\u003e\n\u003cp\u003eStick to the dwell time: 2–5 minutes is enough for typical road grime. Don't let it dry on — in direct sun or high temperatures, mist the car lightly in between or shorten the dwell time accordingly. After the dwell, rinse thoroughly with the pressure washer, then move into the normal shampoo wash. Alternatively, the MultiClean Alkaline can be run as a foam cleaner in the foam cannon — foam clings to the surface longer and stretches the effective dwell time with no extra effort. For really stubborn bug splatter on the front end, it pays to work a soft bug sponge or microfibre mitt over it after the pre-wash before you rinse — even that is already a lot gentler than going straight into a contact wash with no chemical pre-wash first.\u003c\/p\u003e\n\n\u003ch3\u003eBug remover for pros — when the alkaline pre-cleaner really shines\u003c\/h3\u003e\n\u003cp\u003eThe MultiClean Alkaline shows its strengths above all in the summer season, when bugs turn into a real cleaning problem. Bug residue is made of proteins, acids (formic acid, acetic acid) and fatty substances — a chemically complex mix that \"bakes\" into the paint the moment it sits for more than a few hours. Those acids in particular can damage paint if bugs aren't removed promptly in hot weather. The high-alkaline formula neutralises those acids and breaks down the protein structures at the same time — which makes the pre-cleaner an effective tool against bugs that cuts the mechanical load during the wash down to a minimum.\u003c\/p\u003e\n\u003cp\u003eA simple rule of thumb applies: the fresher the bug residue, the less dwell time the cleaner needs. Fresh splatter dissolves almost completely within 2–3 minutes of dwell time and then rinses off touchless. With older, dried-on residue — what you see day-to-day on cars left unwashed for several days after a motorway run — a second pass or a quick mechanical follow-up with a soft bug sponge may be needed. That's not a weakness of the cleaner, it's chemical reality: proteins that have been \"baked\" by heat and UV over days need more time or mechanical help to dissolve fully.\u003c\/p\u003e\n\u003cp\u003eBeyond the car body, it's especially worthwhile on motorhomes, vans and commercial vehicles: thanks to their size and mileage, these often carry many times the dirt load of a normal car, and the option of a touchless pre-wash saves a lot of time and effort here. Professional detailing operations run the pre-cleaner as a fixed part of their wash routine — as the first step, before pressure or foam come in. That doesn't just lift cleaning quality, it also stretches the lifespan of the wash pads and mitts, because they meet far less coarse grime.\u003c\/p\u003e\n\n\n\u003ch3\u003ePre-cleaners compared — MultiClean Alkaline vs. MultiStar and MultiClean Acid\u003c\/h3\u003e\n\u003cp\u003eThe SONAX PROFILINE range has three cleaners that look similar at first glance but are built for different jobs.

The \u003ca href=\"\/products\/sonax-profiline-multiclean-acid-kraftreiniger-sauer\"\u003eSONAX PROFILINE MultiClean Acid\u003c\/a\u003e is its acidic counterpart: it handles mineral deposits like lime spots, water spots and embedded grime that alkaline cleaners can't shift.

Both versions hold the same concentrate formula — the ideal dilution depends on the soiling level and the application method. In pro work with daily use, the 5-litre container clearly pays off, since the price per litre comes out lower and the bigger canister gives you enough volume for larger vehicles and fleets too.\u003c\/p\u003e\n\u003cp\u003eWho gets the most out of this pre-cleaner? Professional detailers running a structured multi-step method (touchless pre-clean + foam wash + hand wash) who put paint safety first. Hobby detailers looking for an effective answer to stubborn traffic film after long runs or in bug season, without having to reach for aggressive chemistry. Owners of dark or sensitive paint, where wash marring shows up the most and the mechanical cleaning load should be kept to a minimum. And anyone who wants to dial in their wash process: pre-wash consistently and you spare the car, the wash gear, and your time in the long run.\u003c\/p\u003e\n\u003cp\u003eAs a practical workflow for your next wash: park the car in the shade, lay the MultiClean Alkaline down with a foam sprayer or foam cannon, let it dwell for 3–4 minutes, rinse thoroughly with pressure.

A 500 ml bottle covers 3–6 jobs.\u003c\/strong\u003e For the whole front (bonnet, bumpers, windscreen, mirrors) reckon on about 80 ml with light contamination and up to 150 ml after a long motorway run. At 13 EUR for 500 ml that works out at 2.10–4.30 EUR per job – cheaper than a single scratch correction with a polisher.\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 Always spray Bug\u0026amp;Grime onto cool, dry surfaces – never onto warm paint and never in direct sun. Heat makes the product flash off too fast and leaves alkaline residue that's a pain to get off. If you want to clean straight after a long drive: cool the bonnet and bumpers down first with a quick blast of water, then spray. Let it dwell for 3 minutes max. A second pass always beats a longer dwell on the first one.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eSpray on. 3 minutes. Rinse off.\u003c\/h3\u003e\n\u003cp\u003eGYEON Q2M Bug Grime goes on before the actual wash as a pre-wash. It chemically softens bug residue and road film so you don't need any mechanical pressure during the wash itself – that cuts the scratch risk during contact washing right down.\u003c\/p\u003e\n\n\u003cp\u003eSpray the product evenly onto the dry, cool surface – the front end, bumpers, windscreen, mirrors and A-pillars are the usual bug zones. Work from the bottom up so the product doesn't run off too fast and the dwell time stays even.\u003c\/p\u003e\n\n\u003cp\u003eAfter 2–3 minutes, rinse top to bottom with a pressure washer or a strong jet of water. The softened bug residue flows away with the water, no need to touch the surface. Then carry on washing as normal with \u003ca href=\"\/products\/gyeon-q2m-bathe-autoshampoo\"\u003ecar shampoo\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003cp\u003eTiming matters: don't let it dwell longer than 3 minutes. The surfactants in Bug\u0026amp;Grime are saturated after that – a longer dwell adds no cleaning power but does raise the risk of residue on the surface. That's especially true in summer above 25 °C, when the product dries faster.\u003c\/p\u003e\n\n\u003cp\u003eWith stubborn bug residue that's been baked on for days, a single pass won't lift everything. Lay down a second pass and gently agitate with a soft detailing brush. The brush spreads the product and brings fresh surfactants onto the dirt – more effective than a longer dwell.\u003c\/p\u003e\n\n\u003cp\u003eFor spot treatment on the road, Bug\u0026amp;Grime works fine without a pressure washer too: spray straight onto the spot, let it dwell 2–3 minutes and lift it off gently with a damp microfibre, dabbing rather than wiping. Don't wipe over the bug residue – dab the softened material off, that way you avoid scratches even without a water supply.\u003c\/p\u003e\n\n\u003cp\u003eOne more detail for glass: Bug\u0026amp;Grime works just as safely on windscreens as on paint. Bugs on the windscreen are often more of a nuisance than on the bonnet, because they block your view and the wipers just smear the residue around. Spray Bug\u0026amp;Grime onto the dry glass, let it dwell and rinse off – after that the wiper clears streak-free again.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/anwendung-bug-grime.jpg?v=1776026163\" alt=\"GYEON Q2M Bug Grime being sprayed onto a bug-covered vehicle front end\" loading=\"lazy\" width=\"1200\" height=\"800\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eIt dissolves bugs. Not bug etching.\u003c\/h3\u003e\n\u003cp\u003eBug\u0026amp;Grime reliably removes fresh and dried-on bug residue from the paint surface – that's its core job. On top of that, the cleaner lifts road grime films, light tar spots and the typical summer film of pollen and dust off bonnets and windscreens.\u003c\/p\u003e\n\n\u003cp\u003eFirst limit: bug etching in the clear coat. When bug residue sits on the paint in the sun for days, the acids in it chemically etch the clear coat. These etch marks are physical damage to the paint surface – no cleaner can remove them.\u003c\/p\u003e\n\n\u003cp\u003eFor that you need a paint polish to take down the damaged clear coat layer and expose a fresh one. Bug\u0026amp;Grime prevents etching like this by removing the bug residue in time. If you clean within 24 hours of every motorway run, you generally won't find any etch marks.\u003c\/p\u003e\n\n\u003cp\u003eLeave it a week and you have to expect paint damage – especially on dark cars, which heat up more in the sun. Dark paint soaks up more heat, the bug acids react faster, and the etching goes deeper. Here, acting fast is the best paint protection there is – a 500 ml bottle in the boot costs 13 EUR and can save you polishing costs of 200 EUR and up.\u003c\/p\u003e\n\n\u003cp\u003eSecond limit: tar and tree sap. Bug\u0026amp;Grime is formulated for protein-based grime (bugs, bird droppings, biofilm). Hydrocarbon contamination like tar, bitumen and tree sap doesn't react to alkaline surfactants – for that, \u003ca href=\"\/products\/gyeon-q2m-tar-redefined-harzentferner-teerentferner\"\u003eQ²M Tar\u003c\/a\u003e is the right product. For a full summer decontamination: Bug\u0026amp;Grime first for the front, then Tar for sills and wheel arches.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/ergebnis-bug-grime.jpg?v=1776026166\" alt=\"Before-and-after comparison of a bug-covered bonnet after Bug Grime treatment\" loading=\"lazy\" width=\"1200\" height=\"800\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eYour first step in the summer wash workflow\u003c\/h3\u003e\n\u003cp\u003eGYEON Q2M Bug Grime makes sense for anyone who covers long distances regularly between March and October and doesn't want bug build-up drying on the front end. As a pre-wash before every summer wash, the bug remover cuts the scratch risk noticeably. Especially relevant for cars with a ceramic coating or fresh polish, where every micro-scratch shows.\u003c\/p\u003e\n\n\u003cp\u003eIn the Detailing1 wash workflow, Bug\u0026amp;Grime sits right at the start: Bug\u0026amp;Grime on the front → \u003ca href=\"\/products\/gyeon-q2m-foam-schaumreiniger\"\u003eQ²M Foam\u003c\/a\u003e as a pre-foam over the whole car → main wash with Q²M Bathe or Q²M Bathe+ → optionally Q²M WetCoat as a wet sealant. Four steps, under 30 minutes, and the front is clean without a single scratch.\u003c\/p\u003e\n\n\u003cp\u003eBug\u0026amp;Grime takes on the hardest part of the workflow: dissolving the protein-bound grime that the foam cleaner can't handle on its own. Foam softens surface dust and road grime, but dried bug proteins need the higher pH of a dedicated bug remover. The difference is measurable: after a pre-wash with Bug\u0026amp;Grime the wash mitt glides over the front end with no resistance during contact washing – without Bug\u0026amp;Grime you feel every dried bug as drag under the mitt.\u003c\/p\u003e\n\n\u003cp\u003eWhere Bug\u0026amp;Grime is less suited is as a replacement for a full pre-cleaner. If you want to clear road grime off the whole car, you're better off reaching for Q²M Foam as a pre-foam – it covers every surface and lifts general dirt more efficiently than a bug remover. Bug\u0026amp;Grime stays the specialist tool for the front and any spots with bug contamination.\u003c\/p\u003e\n\n\u003cp\u003eIf you only remove bugs now and then and don't need a regular workflow: the 500 ml spray bottle fits in any driver's door and is ready to go as a spot treatment. Spray it on the front right after the motorway, let it dwell, rinse it off at the next self-service bay.\u003c\/p\u003e\n\n\u003cp\u003eIt's the simplest insurance against bug etching in summer. For year-round use or several cars, the 4-litre canister is worth it: same formula, lower price per litre at 15.50 EUR per litre instead of 26 EUR with the 500 ml bottle. The best option for topping up the spray bottle in the boot.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/lineup-bug-grime.jpg?v=1776026170\" alt=\"GYEON Q2M Bug Grime all sizes 500ml 1L 4L side by side on exposed concrete\" loading=\"lazy\" width=\"1200\" height=\"800\"\u003e\u003c\/p\u003e\n","brand":"GYEON","offers":[{"title":"1000 ml \/ 1 liter","offer_id":57019440038223,"sku":"D1-GYEON-Q2MBG1000","price":21.0,"currency_code":"EUR","in_stock":true},{"title":"500ml","offer_id":57019440070991,"sku":"D1-GYEON-Q2MBG500","price":13.0,"currency_code":"EUR","in_stock":true},{"title":"4 liters","offer_id":57019440103759,"sku":"D1-GYEON-Q2MBG4000","price":62.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/gyeon-q2m-bug-and-grime-insektenentferner.png?v=1770931757"},{"product_id":"servfaces-reactive-cleaner-high-concentrate-vorreiniger","title":"Reactive Cleaner (High-Concentrate) Pre-Wash","description":null,"brand":"servFaces","offers":[{"title":"1000 ml \/ 1 litre","offer_id":58910387863887,"sku":"D1-SFV-SF10052","price":17.9,"currency_code":"EUR","in_stock":true},{"title":"10 litres","offer_id":58910387896655,"sku":"D1-SFV-SF10052-1","price":130.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/servfaces-reactive-cleaner-high-concentrate-vorreiniger.png?v=1790721116"}],"url":"https:\/\/detiiling1.com\/collections\/vorreiniger.oembed","provider":"Detailing1","version":"1.0","type":"link"}
