An acid-free cleaner from Dr. Wack in Ingolstadt that chemically breaks down iron-rich brake dust and turns red as it works. Two versions in the range: POWER GEL for cling-strong cleaning and HIGH END for delicate wheels.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003e\u003cstrong\u003eWheel cleaners\u003c\/strong\u003e in Dr. Wack's P21S line are acid-free products that don't scrub baked-in brake dust and rust film off the wheel, they dissolve it chemically. The built-in colour change makes the process visible: when the pH-neutral active hits iron particles, the cleaner shifts from colourless to red-violet. You can see in real time where the grime sits and when it's gone. Within Dr. Wack, P21S is the high-end line, and it's this cleaner family that made the name.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAcid-free, so it's gentle on every type of wheel.\u003c\/strong\u003e Unlike classic acid cleaners, the P21S products go after neither the clear coat nor the sealant. That makes them safe on any wheel, painted, polished, chromed or coated. Typical dwell time is 3 to 5 minutes on a cold wheel.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe colour change is a visible sign it's working.\u003c\/strong\u003e The shift from colourless to red-violet isn't a gimmick, it's a real reaction with the iron in the brake dust. As long as red keeps forming, the cleaner is still working. Once no more red shows, the wheel is clean, no guessing and no reaching for another round.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwo versions for two levels of grime.\u003c\/strong\u003e POWER GEL is thick enough to cling to vertical spokes and lift stubborn crust. HIGH END is the finer formula for regularly cleaned or delicate wheels. Between them, the two cover around 90 percent of typical wheel grime.\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 people spray the cleaner straight onto a hot wheel right after a drive, and that's the most common slip-up. On a wheel over 40 degrees the active flashes off before it can react and can leave streaks behind. Let the wheel cool down first, work in the shade, and keep the surface wet through the full 3 to 5 minutes of dwell. That way you pull the whole chemical effect out of it, not just half.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eWhy P21S sets the benchmark for wheel cleaners\u003c\/h3\u003e\n\n\u003cp\u003eThe P21S cleaning gel for wheels is the product the whole line is known for. Dr. Wack in Ingolstadt runs P21S as its high-end line, and this cleaner is the flagship.\u003c\/p\u003e\n\n\u003cp\u003eAt its core is the acid-free, pH-neutral formula with the colour change. Where a lot of cheap cleaners work through acid or strong alkali and put the clear coat and sealant at risk, P21S bonds the iron chemically instead. Brake dust, which bakes into the wheel's clear coat as fine metal particles every time you brake, gets dissolved rather than scoured off. That's easier on the surface, and it's safe even when you're not sure whether your wheel is painted or coated.\u003c\/p\u003e\n\n\u003cp\u003eWhat sets this cleaner apart from the crowd is that it's predictable. The formula has been stable for years, Made in Germany, and it delivers the same result on any wheel. For Dr. Wack, that reliability is the whole promise: you're not buying the cheapest, but you're buying something that works with no nasty surprises. That's why the line keeps landing near the top in comparison tests and has made a name for itself among pros too.\u003c\/p\u003e\n\n\u003cp\u003eOne technical point that often gets missed: baked-in brake dust isn't simple surface dirt. When you brake, red-hot iron particles come off the disc and hit the wheel at high energy, where they literally bake into the clear coat. Water and a brush alone will never pull those particles out fully. This is exactly where the acid-free chemistry comes in, it converts the metallic iron into a water-soluble compound that rinses away with the rest. That's the difference between a wheel that looks clean and one that's genuinely iron-free.\u003c\/p\u003e\n\n\u003ch3\u003eThe two P21S cleaners in the Detailing1 range\u003c\/h3\u003e\n\n\u003cp\u003eIn the Detailing1 range we carry two acid-free cleaners from the P21S line, each aimed clearly at a different job. They don't compete, they complement each other.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003ca href=\"\/products\/dr-wack-p21s-power-gel-felgenreiniger\"\u003eP21S POWER GEL\u003c\/a\u003e is the cling-strong version. Its thick gel consistency stays put on vertical spokes and deep wheel barrels instead of running straight off. That keeps the active in contact with the brake dust for the full 3 to 5 minutes. POWER GEL is the right call when the wheels haven't been cleaned in a while, are heavily crusted, or have a busy multi-spoke design.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003ca href=\"\/products\/dr-wack-p21s-high-end-felgenreiniger\"\u003eP21S HIGH END\u003c\/a\u003e is the finer formula for regular use. It suits wheels that get cleaned often and have only light to moderate brake dust on them, as well as particularly delicate or high-gloss finishes. If you clean your wheels every two to three weeks, HIGH END usually covers everything on its own.\u003c\/p\u003e\n\n\u003cp\u003eBoth share the same basic principle, acid-free, colour change, every type of wheel, and differ mainly in consistency and cleaning power. Keep both on the shelf and you've got everything covered, from a crusted winter set to a freshly sealed summer wheel. That's exactly the upside of a line with two tuned strengths instead of a single compromise product.\u003c\/p\u003e\n\n\u003ch3\u003ePOWER GEL or HIGH END, which one fits\u003c\/h3\u003e\n\n\u003cp\u003eThe choice between the two comes down to two questions: how dirty the wheel is, and how often you clean.\u003c\/p\u003e\n\n\u003cp\u003eGrab the POWER GEL when the wheels are visibly crusted, haven't been touched in a long time, or have a complex shape. The gel clings, doesn't run off, and gives the active the dwell time it needs on a vertical face. On a winter set caked with road-salt brake dust, or on the first clean after a long stretch of neglect, POWER GEL is the safe bet. The thicker layer also means less re-spraying and fewer top-ups.\u003c\/p\u003e\n\n\u003cp\u003eGrab the HIGH END when your wheels are in good shape anyway and you keep on top of them at short intervals. The finer formula is plenty for normal everyday grime and is gentler on the surface. On a delicate polished or chromed wheel you don't want to overwork, HIGH END really plays to its strength. It shows in usage too: clean regularly and you need less product each time, because a thick layer of dirt never builds up in the first place.\u003c\/p\u003e\n\n\u003cp\u003eA simple rule of thumb from what we see day-to-day: POWER GEL for the problem, HIGH END for the routine. If you only want to buy one and have to cover different levels of grime, POWER GEL is the more flexible pick, since it handles light dirt just as easily. If you only ever clean well-kept wheels at short intervals, HIGH END is the finer fit. Ideally you keep both within reach and grab the right strength for the state of the wheel.\u003c\/p\u003e\n\n\u003ch3\u003eHow to use the P21S cleaners the right way\u003c\/h3\u003e\n\n\u003cp\u003eThe workflow is the same for both versions and done in under 10 minutes per wheel. What matters most is temperature and dwell time.\u003c\/p\u003e\n\n\u003cp\u003eStep one: the wheel has to be cold and ideally pre-rinsed. Rinse off loose grit with water so the cleaner can go straight at the baked-in brake dust instead of sand and muck. A cold wheel under 30 degrees is a must, otherwise the active flashes off. Step two: lay the product on generously and all over, until the whole wheel is wetted. With POWER GEL you go on thicker; HIGH END spreads out finer.\u003c\/p\u003e\n\n\u003cp\u003eStep three: let it dwell for 3 to 5 minutes. During that time the colour change shows where it's working, the red-violet streaks are the dissolved iron brake dust. On heavy grime you can work through the spokes with a wheel brush or a soft detailing brush without scratching. Important: never let the cleaner dry out completely. If the wheel is sitting in the sun, cut the dwell time or keep it wet in between.\u003c\/p\u003e\n\n\u003cp\u003eStep four: rinse thoroughly with clean water or a pressure washer until no more red runs off. Then dry the wheel so you don't leave water spots. If you want to protect it afterwards, follow up with a wheel sealant, the next clean then goes much easier because the brake dust has less to hold on to. On very heavily crusted wheels a second pass can make sense: after the first rinse, simply reapply, and the last deep-seated particles let go too.\u003c\/p\u003e\n\n\u003cp\u003eA word on safety: even though the acid-free formula is gentle on materials, disposable gloves and good ventilation are part of clean work. Never spray the cleaner onto a wheel that's still warm and mounted on a rolling car, and avoid long contact with bare aluminium brake calipers. Stick to those three points and you'll work safely and get an even result on every wheel, with no streaks or residue.\u003c\/p\u003e\n\n\u003ch3\u003eP21S compared with Sonax, Koch-Chemie and Gyeon\u003c\/h3\u003e\n\n\u003cp\u003eSeveral makers offer acid-free cleaners with an iron indicator. The honest placement: P21S is in the top group, but not alone at the top.\u003c\/p\u003e\n\n\u003cp\u003eSonax, with the Felgenbeast and FelgenReiniger Plus, offers a broad, easy-to-find range that often sits a little cheaper and cleans solidly day to day. Koch-Chemie, with its reactive products, aims more at the demanding detailer and delivers very aggressive iron-lifting power. Gyeon sits in the premium segment with products like Iron and WheelCleaner, tuned for coated wheels. Against all that, the P21S line is the predictable all-rounder: not the cheapest, not the most specialised, but one of the most reliable across every type of wheel.\u003c\/p\u003e\n\n\u003cp\u003eWhere P21S hits its limit: on extremely neglected wheels with years of baked-on build-up, or on an all-out reconditioning followed by a multi-year ceramic coating, a more specialised brand is sometimes the better addition. For classic wheel cleaning on a care interval of one to four weeks, though, P21S is hard to beat. If you're already in the Dr. Wack world and use A1 on the car and S100 on the bike, P21S gives you the matching wheel counterpart from a single source. For a lot of people that brand consistency is worth more than a marginally stronger rival product, because they're betting on a proven system with predictable results.\u003c\/p\u003e\n\n\u003ch3\u003eWho the P21S cleaner is worth it for\u003c\/h3\u003e\n\n\u003cp\u003eThe P21S cleaner for wheels is worth it for anyone who wants their wheels clean without risking the paint and sealant.\u003c\/p\u003e\n\n\u003cp\u003eFor the beginner, being acid-free is the strongest argument: you can't really go wrong, because the cleaner doesn't attack the surface on any type of wheel. The colour change also takes away the doubt about whether the wheel is already clean. For the keen detailer who cares for their wheels regularly, the fine HIGH END formula is the right routine choice. And for anyone who has to bring a crusted winter set or neglected wheels back into shape, POWER GEL brings the cling and cleaning power you need.\u003c\/p\u003e\n\n\u003cp\u003eAnyone who wants to keep their car's value is in the right place too. Clean, iron-free wheels aren't just a looks thing: baked-in brake dust can eat into the wheel's clear coat over time and lead to pitting. A regularly used acid-free cleaner prevents that without stressing the surface itself. Over the years, that's cheap protection for an expensive part.\u003c\/p\u003e\n\n\u003cp\u003eOur starter tip: if you only buy one product and want to cover different levels of grime, grab the \u003ca href=\"\/products\/dr-wack-p21s-power-gel-felgenreiniger\"\u003eP21S POWER GEL\u003c\/a\u003e, it's more flexible.

An acid-free cleaning gel from Dr. Wack that chemically binds iron-bearing brake dust and turns red-violet while it does it. Approved for painted, anodised, mirror-polished and chrome wheels. Not a paint cleaner, not a sealant, and nothing for a warm wheel straight off a drive.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003e\u003cstrong\u003eP21S POWER GEL wheel cleaner\u003c\/strong\u003e is an acid-free cleaning gel from Dr. Wack for painted, anodised, mirror-polished and chrome wheels in alloy and steel. Its active ingredient, sodium mercaptoacetate, thioglycolate in the trade, locks the iron compounds out of brake dust into a water-soluble cage. Day-to-day that means the black deposit runs off with the rinse water instead of spreading across the spokes under a brush.\u003c\/p\u003e\n\n\u003cp\u003eThe gel consistency is not thickener for show. 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.

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.

Instead of running off, the gel sits evenly across the surface – even on vertical faces. That gives the active components longer to work and they bite harder. Over the dwell time (about 3–5 minutes) they cut through layers of brake dust, metal particles and oil residue. The signature colour indicator shows you the progress: once the cleaner turns purple to black, the dirt is lifted and rinses straight off. That colour change comes from iron complexation – a visible sign the chemistry is doing its thing.\u003c\/p\u003e\n\u003ch3 data-start=\"2044\" data-end=\"2082\"\u003eHow to use it \u0026amp; the right dwell time\u003c\/h3\u003e\n\u003cp data-start=\"2083\" data-end=\"2810\"\u003eUsing the \u003cstrong data-start=\"2101\" data-end=\"2145\"\u003eDr. Wack P21S \"High End\" Wheel Cleaner\u003c\/strong\u003e couldn't be simpler or safer. Spray it evenly onto dry, cooled-down wheels – best from about 20 cm away. Then let it dwell for 3–5 minutes, until the purple colour is clearly showing. After that, rinse off well with a strong jet or pressure washer. With really baked-in grime a soft wheel-brush set gives it a hand. Important: don't use it on hot wheels or in direct sun. The cleaner is fine on all materials, including delicate TPMS sensors. Thanks to the pH-neutral formula there's no corrosion on metal, paint or plastic parts.\u003c\/p\u003e\n\u003ch3 data-start=\"2812\" data-end=\"2871\"\u003eResults, material safety \u0026amp; where to use it\u003c\/h3\u003e\n\u003cp data-start=\"2872\" data-end=\"3654\"\u003eThe \u003cstrong data-start=\"2876\" data-end=\"2910\"\u003eP21S \"High End\" Wheel Cleaner\u003c\/strong\u003e delivers no-compromise results – even where other products tap out.
