The high-end care line from Dr. O.K. Wack Chemie in Ingolstadt, built around the wheel, the tyre and bare metal. At its core sits the acid-free wheel cleaner with a colour change that visibly dissolves iron-rich brake dust. Alongside it: rim wax, tyre shine and metal polish as a matched system.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003e\u003cstrong\u003eDr. Wack P21S\u003c\/strong\u003e is Dr. Wack's high-end line for wheel and tyre care. It made its name through two acid-free wheel cleaners with a colour change: on iron-rich brake dust they turn from colourless to red-violet, showing you in real time exactly where the load sits. Acid-free means the formula is built for painted wheels and doesn't rely on aggressive acid. Around that core sit a rim wax, a tyre shine, a metal polish and a quick detailer, a matched system all from one house.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwo cleaning strengths instead of one compromise.\u003c\/strong\u003e P21S covers the everyday with the POWER GEL and the stubborn cases with the HIGH END. Both work acid-free and with a colour change, and the typical dwell window is 3 to 5 minutes on a cold wheel. Two tools for two levels of grime, not one do-it-all bottle for everything.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFour care steps from a single line.\u003c\/strong\u003e Clean, seal, shine, polish: P21S gives you a dedicated product for each of these steps, from the wheel cleaner through the rim wax to the tyre shine and the metal polish. That builds one continuous workflow instead of hunting down four products from four different brands.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMade in Germany since 1975.\u003c\/strong\u003e Dr. Wack produces the P21S formulas in Ingolstadt, with over 45 years of experience in vehicle care. The real value here is how predictable those stable formulas are: every bottle gives you the same result, so you don't have to re-dial the application every single time.\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 We often see the wheel cleaner sprayed onto a hot wheel straight after a drive. That's the single most common mistake across this whole category: on a warm wheel the gel dries on before it can work, and the colour change comes out patchy. Let the wheel cool to hand-warm first, then spray it on generously from the bottom up, give the gel 3 to 5 minutes and rinse off with a strong jet of water. On polished or chromed wheels, test on a hidden spot first.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eOne line for the demanding wheel job\u003c\/h3\u003e\n\u003cp\u003eDr. Wack P21S is the brand's answer to an area where the rest of the range deliberately stays solid: no-compromise wheel care. While A1 makes up the all-round car line and S100 the motorcycle line, P21S plays a level higher and is the only line the brand openly labels high end right there in the product name.\u003c\/p\u003e\n\u003cp\u003eThe reason is the substrate. Wheels are the hardest-worked painted surface on the car. Brake dust from hot iron particles practically burns itself into the surface, and road salt and tar pile on over winter. Work here with an all-purpose cleaner that's too mild and you'll be scrubbing forever; reach for acid that's too aggressive and you put the wheel's clear coat at risk. That's why P21S sticks firmly to acid-free formulas that dissolve iron chemically rather than raw acid power.\u003c\/p\u003e\n\u003cp\u003eThis positioning also explains why the line is so lean and focused. P21S isn't after 30 products for every niche, but a handful of tools that cover the wheel and metal job in full, from cleaning to sealing. That's exactly what makes it interesting for anyone who takes their wheels seriously and doesn't want to improvise from scratch every time.\u003c\/p\u003e\n\u003cp\u003eAt Detailing1, P21S is therefore the entry point we recommend when someone is looking to tackle baked-on brake dust for the first time and doesn't want to buy a bottle of acid on a hope and a prayer. The brand takes that decision off your hands by taking the risk out of the formula in the first place.\u003c\/p\u003e\n\u003cp\u003eIn the Detailing1 range we currently carry six active P21S products, from the two wheel cleaners through sealing and tyre care to the metal polish. That lets you map the complete wheel workflow without switching brands. Start with a single 750 ml bottle and you can always build the system upward later.\u003c\/p\u003e\n\n\u003ch3\u003eAcid-free, and the trick with the colour change\u003c\/h3\u003e\n\u003cp\u003eThe technical heart of P21S is acid-free wheel chemistry with a visual working indicator. Instead of attacking the surface with acid, the cleaners dissolve the iron-rich brake dust chemically and turn red-violet as they do it.\u003c\/p\u003e\n\u003cp\u003eThat colour change isn't for show, it's a genuine working aid. The colour shift shows you in real time where the iron sits and how heavily the wheel is loaded. As long as fresh red keeps coming through, the chemistry is still working; once nothing more changes colour, the dissolvable brake dust is out and you can rinse. So you're not guessing at the dwell time, you read it straight off the wheel.\u003c\/p\u003e\n\u003cp\u003eAcid-free is the second key promise here. The formula is built for painted wheels, meaning the clear-coated alloy and steel wheels that are the norm today. It doesn't attack the clear coat and goes on without any protective-glove drama, unlike the classic acid cleaners you used to handle only in full kit.\u003c\/p\u003e\n\u003cp\u003eThe honest limit is part of the truth too: polished aluminium and chromed surfaces are more delicate than painted wheels, because they lack that protective coat of paint. Here you should test the cleaner on a hidden spot before the first full go, leave it on for just 1 to 2 minutes instead of the full 3 to 5, and rinse thoroughly straight away. For the vast majority of painted factory wheels it's a non-issue; for the special cases it stays a deliberate move.\u003c\/p\u003e\n\u003cp\u003eSo in practice it's the type of wheel that decides your approach, not the product. Painted alloy and steel wheels get the full pass, delicate special finishes a shortened one. That keeps one and the same acid-free cleaner usable on almost any set of wheels, as long as you match the dwell time to the material.\u003c\/p\u003e\n\n\u003ch3\u003ePOWER GEL and HIGH END as a pair of tools\u003c\/h3\u003e\n\u003cp\u003eAt its core, the Dr. Wack P21S range is two wheel cleaners that don't replace each other but work together. The \u003ca href=\"\/products\/dr-wack-p21s-power-gel-felgenreiniger\"\u003eP21S POWER GEL wheel cleaner\u003c\/a\u003e is the original and the workhorse for regular care, available from the 100 ml tester to the 5-litre canister.\u003c\/p\u003e\n\u003cp\u003eThe gel clings vertically to the wheel instead of running straight off, so it makes full use of the 3 to 5 minutes of dwell time. For the everyday driver washing their wheels every two to four weeks, the POWER GEL is usually all it takes. The 750 ml and 1000 ml bottles with a spray head cover the typical need most conveniently, there's 100 ml for a small sample, and the 5-litre canister for heavy users.\u003c\/p\u003e\n\u003cp\u003eThe \u003ca href=\"\/products\/dr-wack-p21s-high-end-felgenreiniger\"\u003eP21S HIGH END wheel cleaner\u003c\/a\u003e is the stronger step for the cases where the POWER GEL reaches its limit: deeply baked-in brake dust, long-neglected wheels, hard-driven cars with a heavy brake load. It triggers the same mechanism but works noticeably harder, and stays acid-free doing it.\u003c\/p\u003e\n\u003cp\u003eKeep both cleaners on the shelf and you'll have the easiest time of it. The POWER GEL handles the routine; the HIGH END comes out when a set of wheels needs a real deep clean after winter or before the seasonal changeover. You'll find both together in the \u003ca href=\"\/collections\/dr-wack-p21s-felgenreiniger\"\u003eP21S wheel cleaner selection\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eClean, seal, shine, in that order\u003c\/h3\u003e\n\u003cp\u003eP21S treats wheel care as a chain, not a single step. The clean sequence is: thorough clean first, then seal, then treat the tyre, and polish metal parts separately.\u003c\/p\u003e\n\u003cp\u003eStep one is handled by the wheel cleaner on a cold wheel, with 3 to 5 minutes of dwell time. Once the wheel is clean and dry, the \u003ca href=\"\/products\/dr-wack-p21s-felgen-wachs-felgenversiegelung\"\u003eP21S rim wax\u003c\/a\u003e goes on top as a sealant. It lays a protective film on alloy and steel wheels that fresh brake dust clings to less well, so the next wash goes easier. The 400 ml tin is enough for several sets of wheels, and even one pass every few months saves you noticeable scrubbing over time.\u003c\/p\u003e\n\u003cp\u003eThe rim wax is the most underrated step in the line. Plenty of people clean their wheels flawlessly but skip the sealant, then wonder why the brake dust is stuck fast again after just two weeks. The sealant stretches exactly that interval: instead of having to scrub at full force, next time a mild 2-minute pass is often all it takes. That small bit of extra effort pays off over the weeks.\u003c\/p\u003e\n\u003cp\u003eFor the tyre, the \u003ca href=\"\/products\/dr-wack-p21s-reifen-glanz-reifenpflege\"\u003eP21S tyre shine\u003c\/a\u003e brings dull, greyed rubber back to a deep black and cares for the sidewall at the same time. The order matters: always apply tyre dressing after cleaning the wheels, otherwise you'll rinse the freshly applied shine straight back off while cleaning. The 400 ml tin is enough for plenty of tyre sets, and you can dose the shine to taste, from subtly cared-for to wet-look.\u003c\/p\u003e\n\u003cp\u003eThe fourth step is covered by the \u003ca href=\"\/products\/dr-wack-p21s-metall-alu-polish-metallpolitur\"\u003eP21S metal and alu polish\u003c\/a\u003e. It isn't a wheel cleaner but a polish for bare metal parts like polished exhaust tips, trim strips or unpainted aluminium components, bringing them to a high shine. The 100 ml tube is small on purpose, because a polish is applied sparingly and buffed out, not sprayed over large areas. If you're out and about, freshen up between times with the P21S rim detailer, a heat-resistant quick detailer from the 500 ml spray bottle that lifts dust and fingerprints without a full wash.\u003c\/p\u003e\n\u003cp\u003eThat's how the products mesh: the cleaner lays the base, the wax makes it last longer, the tyre shine and the metal polish set the visual accents, and the detailer bridges the time between two full washes. Nobody has to run all five steps at every session. But once you know the system, you know exactly which product comes off the shelf for which occasion.\u003c\/p\u003e\n\n\u003ch3\u003eWhere P21S sits in the market\u003c\/h3\u003e\n\u003cp\u003eAmong the acid-free wheel cleaners with a colour change, Dr. Wack P21S clearly plays in the top league. The category is well stocked, from Sonax through Koch-Chemie to specialist detailing brands, and P21S counts as one of the classics that many people measure themselves against.\u003c\/p\u003e\n\u003cp\u003eThe strength of P21S is how predictable it is across the whole line. You don't just get a strong cleaner but a wheel system that hangs together, from a maker that has produced in Ingolstadt since 1975. That takes away the uncertainty over whether the sealant suits the cleaner or the tyre shine attacks the wheel, because it all comes from one house.\u003c\/p\u003e\n\u003cp\u003eWhere the line deliberately stops is no-compromise paint correction. P21S polishes metal and seals wheels, but it doesn't replace a system of cutting polishes in several grades, nor a multi-year ceramic coating. If you want to fully restore a wheel after a kerb strike or coat it in ceramic for the long haul, you add a specialist brand for that. For ongoing care up to protective sealing, though, P21S is complete.\u003c\/p\u003e\n\u003cp\u003eThat honesty is part of the recommendation. P21S doesn't promise anything it can't deliver, and that's exactly why it's a reliable standard for us, one we're happy to pass on to beginners and seasoned spanner-hands alike.\u003c\/p\u003e\n\n\u003ch3\u003eYour way into the P21S system\u003c\/h3\u003e\n\u003cp\u003eAnyone wanting to start with Dr. Wack P21S only needs two products to get going. The POWER GEL as the cleaner and the rim wax as the sealant together form the backbone that gets your wheels clean and keeps them clean for longer.\u003c\/p\u003e\n\u003cp\u003eIf you drive a lot, brake hard or have long-neglected wheels in front of you, add the HIGH END on top for the real problem cases. That three-way combo covers just about every wheel situation that comes up day-to-day, from a lightly dusty summer wheel to a baked-on winter set.\u003c\/p\u003e\n\u003cp\u003eWant the tyre to keep up too? The tyre shine rounds out the set, and if you've got polished metal parts on the car, grab the metal and alu polish as well. That way you build up the complete wheel system step by step, without having to buy everything from the start.\u003c\/p\u003e\n\u003cp\u003eFor an overview of the whole brand there's the \u003ca href=\"\/collections\/dr-wack\"\u003eDr. Wack brand world\u003c\/a\u003e; if you want to move from the wheel to the rest of the car, the \u003ca href=\"\/collections\/dr-wack-a1\"\u003eA1 car care range\u003c\/a\u003e has the matching wash and interior products, and the \u003ca href=\"\/collections\/dr-wack-s100\"\u003eS100 motorcycle care range\u003c\/a\u003e the line for two wheels.

Then spread it evenly over the wheel and buff off with the dry side. This step brings instant gloss and leaves an even protective layer. If you want to push the long-term effect further, keep the treated wheels away from moisture for about two hours. Day-to-day from Detailing1: use two cloths – one to spread, one to wipe – and you get a flawless finish with no streaks. The detailer lifts light dirt and dust, which makes it ideal for a quick clean between washes or as a finish after the main wash.

A thin cleaner slides down a vertical wheel face in seconds and takes its reaction time with it. The POWER GEL stays where the spray puts it: on the hub, down in the spoke roots, on the rim flange. It is that cling time that turns three minutes of dwell into three minutes of contact.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThree minutes is enough, below ten degrees it is not.\u003c\/strong\u003e Dr. Wack gives 3 to 5 minutes of dwell time. If the temperature drops below 10 °C or the wheel is heavily caked, the manufacturer itself stretches that to at least 10 minutes. Work in February on summer timing and you rinse the reaction away before it has finished.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe colour is a readout, not a bonus effect.\u003c\/strong\u003e The gel goes onto the wheel pink, so you see straight away every spot the spray missed. Wherever iron-bearing dust is sitting, the colour pulls through to a dark red-violet. After 3 minutes you know whether a second pass is needed before you even touch the hose.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFour container sizes, one formula.\u003c\/strong\u003e 750 millilitres with a trigger gun, 2 and 5 litres as canisters, 25 litres as a refill station. Between the small bottle and the big containers the price per litre drops by around a third without a thing changing in the mix. What you lose is the spray head.\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 We get a lot of questions about a whitish film left on the wheel after rinsing. That is usually not residue from the gel but limescale out of the rinse water, drying onto the warm wheel while you are standing at the next one. So work through wheel by wheel: spray, wait 3 to 5 minutes, rinse, wipe down with the drying towel, and only then the next one. Spraying all four at once looks like a time saver and costs you the second pass.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eBelow ten degrees the POWER GEL needs ten minutes\u003c\/h3\u003e\n\u003cp\u003eSpray onto the cold, dry wheel, wait 3 to 5 minutes, rinse off with a strong jet of water. Below ten degrees or with heavy brake dust, Dr. Wack stretches that to at least 10 minutes.\u003c\/p\u003e\n\n\u003cp\u003eCold means: a quarter of an hour after the last hard braking, and not in direct sun. A wheel that has just come off the motorway still carries the residual heat of the brake disc in its face. The gel dries on there before the reaction is through, and afterwards you are scrubbing dried cleaner instead of brake dust.\u003c\/p\u003e\n\n\u003cp\u003eDry is the second half of the condition. Hose the wheel down first and you dilute the gel at the moment you lay it on, weakening exactly the property you bought it for. Spray from the bottom up so gel running down always meets untreated surface, and take in the hub, the spoke roots and the edge against the tyre on purpose. Loose grit on the wheel is no problem, it comes off with it.\u003c\/p\u003e\n\n\u003cp\u003eOn quantity: generous, but not twice over. The gel works through contact, not through layer thickness, and a second coat onto a first one that is still wet buys you nothing but consumption. In the MOTORRAD hands-on test it was exactly this cling that explained the low usage: whatever stays up there needs no topping up. On a deep-dish wheel with narrow spokes a short second burst into the spoke roots still pays, because that is where the least gel arrives.\u003c\/p\u003e\n\n\u003cp\u003eRinsing then runs top down, until no pink haze comes off any more. Wheels come before the paint in the wash order, otherwise you carry the dissolved iron dust over the doors afterwards. If a residue is left after rinsing, a second short pass is the right answer, not a longer dwell. Users agree across the board that an hour of contact gets you no more than ten minutes does.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/dr-wack-p21s-power-gel-felgenreiniger_anwendung.jpg?v=1787867974\u0026amp;width=1400\" alt=\"P21S POWER GEL wheel cleaner being sprayed onto the cold alloy wheel\" loading=\"lazy\" decoding=\"async\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eThe colour change flags the brake dust, the dwell time is what dissolved it\u003c\/h3\u003e\n\u003cp\u003eThe colour change is an indicator, not a cleaning step. It tells you where iron-bearing dust is sitting. The work was done by the minutes before it, not by the colour.\u003c\/p\u003e\n\n\u003cp\u003eThat is more than splitting hairs, because two wrong expectations hang off it. First: a wheel where almost nothing changes colour is no proof of a weak product, it is usually a wheel with little iron on it. Second: a deep violet wheel is not clean yet, it is marked. It only gets clean once the bound dust is in the rinse water.\u003c\/p\u003e\n\n\u003cp\u003eTwo hard limits go with that. The POWER GEL cleans, it does not protect. After rinsing, the wheel surface is bare and open, and the next lot of brake dust keys in just as fast. If you want to stretch the cleaning intervals, you lay a \u003ca href=\"\/collections\/felgenreiniger\"\u003ewheel sealant\u003c\/a\u003e on afterwards, otherwise you start from zero every two weeks. And on wheels that have seen a whole winter season through, one pass is rarely enough. Two goes of three minutes beat one of twenty.\u003c\/p\u003e\n\n\u003cp\u003eOn mirror-polished and anodised surfaces Dr. Wack recommends a compatibility test on a hidden spot before the first use. And the smell: thioglycolate compounds have a sharp odour, the formula now carries fragrance on top, and that does not make it odour-free. In an enclosed space you notice it clearly, outdoors barely at all.\u003c\/p\u003e\n\n\u003cp\u003eThat leaves the line on the label. \"Repeat test winner\" holds for the range, not automatically for this bottle: in the AUTO BILD comparison in issue 22\/2021 with eleven wheel cleaners, it was the \u003ca href=\"\/products\/dr-wack-p21s-high-end-felgenreiniger\"\u003eP21S HIGH END wheel cleaner\u003c\/a\u003e that stood top with 183 out of 200 points, not the POWER GEL. That is not a mark against it, it is a question of who entered: the POWER GEL was not in that field.\u003c\/p\u003e\n\n\u003cp\u003eThe test figure you can pin on this bottle comes from the MOTORRAD hands-on test, which landed on 4 out of 5 stars. It praised the cling and the material compatibility on paint and chrome, and criticised a spray head that worked itself loose in use. If you want the formula that went through the comparison test, take the HIGH END. If you need gel cling, a colour readout and big containers, you are in the right place here.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/dr-wack-p21s-power-gel-felgenreiniger_anwendung_2.jpg?v=1787867980\u0026amp;width=1400\" alt=\"Pink gel of the P21S POWER GEL on the vertical face of a VW alloy wheel\" loading=\"lazy\" decoding=\"async\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eDr. Wack builds the POWER GEL as a refill system, not as a one-way bottle\u003c\/h3\u003e\n\u003cp\u003eThe POWER GEL comes in four container sizes from 750 millilitres to 25 litres. The big canisters carry no spray head, they are meant for refilling and not for direct use.\u003c\/p\u003e\n\n\u003cp\u003eFor one car that comes round every two to three weeks, the 750 millilitre bottle with the trigger gun is the right size. It is ready to go, it stands on the shelf without decanting, and it is the only version Dr. Wack ships with a trigger gun. From the second car in the household, with winter and summer wheels running in parallel, or with a driving style that makes the dust to match, the maths tips towards the 2 or 5 litre canister.\u003c\/p\u003e\n\n\u003cp\u003eThe 25 litre refill station is no clearance lot from a different batch. It is the same mix that runs into the 750 millilitre bottle in Baar-Ebenhausen, just without a trigger gun in the box. Dr. Wack has carried the product since 1976, and the spread of container sizes follows from that: hold a formula stable for half a century and you can fill it into the same bottle and the same drum for everyone from the home driveway to the tyre fitter.\u003c\/p\u003e\n\n\u003cp\u003eWho the product is not built for belongs in the picture just as much. If you wash your car twice a year and let the wheels run in between, this is no one-shot rescue for baked-on deposits, it is a product that plays its advantage with regular use. On a painted winter wheel that has taken a season of chippings and road grit, the first pass takes the brake dust off and leaves the rest standing; only the second one makes it even.\u003c\/p\u003e\n\n\u003cp\u003eAnd if you are only after shine, a \u003ca href=\"\/products\/dr-wack-p21s-felgen-wachs-felgenversiegelung\"\u003ewheel wax\u003c\/a\u003e serves you better than a cleaner. The POWER GEL takes away, it lays nothing on.\u003c\/p\u003e\n\n\u003cp\u003eOne detail no manufacturer text mentions and that regularly causes grief with the big container: the 25 litre refill station comes without a tap. Order the drum with no tap and no pressure sprayer in the house and you are standing there with 27 kilos of gel you cannot get at. Two minutes of thought before you order save you a week of waiting with a full canister and an empty spray bottle.\u003c\/p\u003e","brand":"Dr. Wack \"P21S\"","offers":[{"title":"750ml","offer_id":54707217039695,"sku":"D1-DRW-1253","price":22.99,"currency_code":"EUR","in_stock":true},{"title":"2 liters","offer_id":54707217137999,"sku":"D1-DRW-1265","price":39.99,"currency_code":"EUR","in_stock":true},{"title":"5 liters","offer_id":54707217170767,"sku":"D1-DRW-1256","price":100.99,"currency_code":"EUR","in_stock":true},{"title":"25 liters","offer_id":56260456939855,"sku":"D1-DRW-1257","price":505.99,"currency_code":"EUR","in_stock":true},{"title":"1000ml","offer_id":56260456874319,"sku":"D1-DRW-1252","price":29.99,"currency_code":"EUR","in_stock":true},{"title":"100ml","offer_id":56260456907087,"sku":"D1-DRW-1251","price":5.9,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/dr-wack-p21s-power-gel-felgenreiniger.png?v=1787867588"},{"product_id":"dr-wack-p21s-high-end-felgenreiniger","title":"P21S \"HIGH END\" Wheel Cleaner","description":"\u003ch2 data-start=\"0\" data-end=\"88\"\u003eDr. Wack P21S \"HIGH END\" Wheel Cleaner – uncompromising power, easy on the metal\u003c\/h2\u003e\n\u003cblockquote\u003e\n\u003cp data-start=\"90\" data-end=\"325\"\u003e\u003cem data-start=\"90\" data-end=\"146\"\u003eHow does the Dr. Wack P21S \"High End\" Wheel Cleaner work?\u003c\/em\u003e\u003cbr data-start=\"146\" data-end=\"149\"\u003eIt pulls even baked-on brake dust, oil and rubber off the wheel on its own thanks to a clinging gel and a colour indicator – fast, gentle and even when it's cold out.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\u003chr data-start=\"327\" data-end=\"330\"\u003e\n\u003cp data-start=\"332\" data-end=\"817\"\u003eThe \u003cstrong data-start=\"336\" data-end=\"379\"\u003eDr. Wack P21S \"High End\" Wheel Cleaner\u003c\/strong\u003e is the premium wheel cleaner for anyone who wants flat-out cleaning power without putting paint, metal or seals at risk.

You notice it like this: on a warm day the film goes matt and ready to wipe faster than it does somewhere cool and shaded.\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 We see the most expensive mistake regularly before the tube is even open — anodised and clear-coated aluminium looks like bare metal but carries a protective layer that this polish takes off with everything else. So run the white cloth test: a pea-sized blob on a white cotton cloth, rubbed on a hidden patch for twenty seconds. If the mark goes grey to black, you have bare metal in front of you, because that residue is the oxide layer. If the cloth stays white, there is anodising or clear coat on top, and that is where the polish stops.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eYou polish the whole strip, never just the dull patch.\u003c\/h3\u003e\n\u003cp\u003eThe paste goes onto polishing wadding and not straight onto the metal, gets worked in with pressure, flashes off briefly and is then wiped away with a clean microfibre cloth.\u003c\/p\u003e\n\n\u003cp\u003eWash first, dry second, polish third. On a dirty surface you grind loose grit along under the wadding, and the fine lines that leaves show up more clearly on polished metal than on paint. A surface that mirrors shows every mistake twice over.\u003c\/p\u003e\n\n\u003cp\u003eThe reason for the wadding is dosing. Put the paste straight onto the surface and it sits too thick in one spot and spreads unevenly on the first pass. On the wadding the same amount spreads across the whole contact face, and the pressure from your hand arrives evenly at the metal. That is exactly what sits behind the AUTO BILD sub-score for spreadability.\u003c\/p\u003e\n\n\u003cp\u003eThe second rule is in small print on the tube and gets skipped over constantly: for an even result you always work the whole surface. Go at the dull patch on the tailpipe on its own and you end up with two states side by side and a visible line between them. A chrome strip gets done edge to edge, a tailpipe all the way round, a wheel as a whole.\u003c\/p\u003e\n\n\u003cp\u003eOn painted surfaces, painted alloy wheels for instance, the manufacturer explicitly calls for minimal effort. There is no oxide there, there is paint, and paint will not take the pressure bare metal needs. If you are doing several metal parts in one go, the \u003ca href=\"\/collections\/dr-wack-metallpolitur\"\u003emetal polishes from Dr. Wack\u003c\/a\u003e also run to the motorcycle version, built around the same way of working.\u003c\/p\u003e\n\n\u003cp\u003eBrown speckles on stainless tailpipes are usually fallout, foreign iron particles that have taken hold. The polish takes those off mechanically. A chemical decon step does dissolve them more gently, but it does not bring back the shine the surface needs afterwards.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/dr-wack-p21s-metall-alu-polish-metallpolitur_anwendung.png?v=1787867970\u0026amp;width=1400\" alt=\"P21S Metall-\/ Alu-Polish being dosed onto a wad of polishing wadding in front of the wheel\" loading=\"lazy\" decoding=\"async\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eAnodised alu does not get polished, it gets taken off.\u003c\/h3\u003e\n\u003cp\u003eAnodising is not paint and not colour, it is an oxide layer grown on the aluminium in a bath, so exactly the material this polish is built to take off.\u003c\/p\u003e\n\n\u003cp\u003eThe paste plays to its strength wherever bare metal is out in the air: stainless tailpipes, chrome trim on a modern classic, unpainted forged wheels, motorcycle parts, brass and copper fittings. There is a genuine oxide layer there, and the dark streak you see on the cloth afterwards is the proof that it is off.\u003c\/p\u003e\n\n\u003cp\u003eThe manufacturer draws two hard limits. Anodised aluminium stays off limits, because the anodised layer is itself the protection and the abrasion simply takes it with it. What appears underneath is unprotected raw material. And on chromed plastic parts the paste has no business: the chrome sits there as a wafer-thin metal film on the plastic and you have polished through it before you notice.\u003c\/p\u003e\n\n\u003cp\u003eWhat the paste also does not do: deep scoring, pitting and corrosion that has already eaten into the material. It works at the surface, not down in it. If you are bringing a chrome strip or a tailpipe up to a mirror shine by hand, this is the right tool. If a large dull alu panel has to be cut back by machine first, you reach for the \u003ca href=\"\/products\/sonax-profiline-metalpolish-metallpolitur\"\u003emetal polish with a medium cut\u003c\/a\u003e and come back to this paste for the finish.\u003c\/p\u003e\n\n\u003ch3\u003eThe shine is a state with a shelf life, not a result.\u003c\/h3\u003e\n\u003cp\u003eBare metal starts reacting with the oxygen in the air again from the first moment, which is why metal polish is a rhythm and not a one-off appointment.\u003c\/p\u003e\n\n\u003cp\u003eThat is exactly what the protective film left by the paste works against. It slows the tarnishing, it does not stop it. How long it lasts is something Dr. Wack deliberately does not state for this product, and that is fair enough: a tailpipe in winter use stands in a different place from a trim strip on a car kept under cover. On wheels you put a \u003ca href=\"\/products\/dr-wack-p21s-felgen-wachs-felgenversiegelung\"\u003ewheel sealant\u003c\/a\u003e from the same line over the top and stretch the interval noticeably.\u003c\/p\u003e\n\n\u003cp\u003eThe tube makes sense for anyone living with unpainted metal on the car: modern-classic and classic drivers with chrome, riders with polished parts on the bike, detailers who do the stainless tailpipes as the last job before handover. It makes no sense for someone after a permanent fix. If you never want to polish again, have the surface clear-coated and look after the paint from then on, not the metal.\u003c\/p\u003e\n\n\u003cp\u003eCommercially that makes the 100-millilitre tube not a small size but the right one. A pea-sized blob goes onto the wadding per pass, and anyone who keeps to the rhythm gets through less of it than someone working against a full year of oxide once a year. Store it frost-free, tightly closed and away from food.\u003c\/p\u003e\n\n\u003cp\u003eThe trick no tube prints on the label: do not reach for the polish once the surface has gone dull, reach for it while it still shines. On freshly tarnished metal a light pass is enough and barely anything stays on the cloth. On two years of oxide the same shine costs you real material, and what once sticks to the cloth does not come back. Aluminium does not grow back.\u003c\/p\u003e","brand":"Dr. Wack \"P21S\"","offers":[{"title":"100ml","offer_id":54707219333455,"sku":"D1-DRW-1285","price":15.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/dr-wack-p21s-metall-alu-polish-metallpolitur.png?v=1787867578"},{"product_id":"dr-wack-p21s-druck-sprueher-zubehoer","title":"P21S \"Pressure Sprayer\" Pressure Sprayer","description":"\u003ch2 id=\"speakable-headline\"\u003eP21S Felgenreiniger sauber und gleichmäßig aus dem Nachfüllgebinde auftragen\u003c\/h2\u003e\n\u003cblockquote id=\"speakable-summary\"\u003e\u003cp\u003e\u003cem\u003eDer P21S Druck-Sprüher ist ein Aufsprüh-Zubehör für P21S Felgenreiniger aus den Nachfüllgebinden.
