An acid-free wheel cleaner with a color-changing indicator that chemically dissolves iron particles on steel, aluminum, and chrome wheels — including TPMS approval. Not suitable for freshly repainted wheels, burnt-in tar, or hot surfaces directly after driving.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003e\u003cstrong\u003eSONAX WheelBeast\u003c\/strong\u003e is an acid-free wheel cleaner from SONAX that works with a chemical indicator: The gel changes from transparent to reddish-purple within 60 to 90 seconds as soon as it reacts with iron particles from brake dust. The active ingredient, based on thioglycolate, binds the trivalent iron compounds and converts them into water-soluble complexes, which can then be rinsed off without leaving any residue.\u003c\/p\u003e\n\n\u003cp\u003eThe wheel surface remains unaffected during this process because the cleaner reacts chemically only with iron and not with clear coat, powder coating, or anodized aluminum. This fundamentally differentiates WheelBeast from acid-based cleaners, which work faster but can leave irreversible etching marks on polished aluminum or chrome. This is particularly critical for OEM wheels with diamond cut finishes, where any minimal material abrasion remains permanently visible and cannot be polished out.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_sonax-felgenbeast-felgenreiniger_hero.png?v=1775901568\" alt=\"SONAX FelgenBeast spray bottle in front of Porsche 911 GT3 RS wheel\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor change as a real-time diagnostic.\u003c\/strong\u003e The reddish-purple discoloration not only shows you whether you have applied it comprehensively, but also where brake dust is still lodged in pores and spoke edges that you can't see with the naked eye. After 3 minutes, you'll know which areas need a second pass, and you won't have to check the cloth afterwards to see if the wheel is really contamination-free.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOne product for your entire fleet.\u003c\/strong\u003e WheelBeast is approved for steel, alloy, painted, chrome, polished, and matte wheels — and is fully TPMS-compatible. You don't need a second cleaner for winter wheels and a third for OEM diamond-cut alloys. The only exception: repainted wheels that are no longer originally powder-coated.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwo containers for two user types.\u003c\/strong\u003e The 1-liter spray bottle lasts approximately 3 months with bi-weekly cleaning of one vehicle. The 5-liter canister is intended for multi-vehicle households and commercial detailers — 1 liter per wheel set corresponds to about 20 complete washes per container, which significantly reduces the price per liter.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDetailing1 Pro Tip:\u003c\/strong\u003e The most common mistake with WheelBeast is applying it to wet or hot wheels. Wet wheels dilute the gel by 30 to 50 percent — the dwell time is then not sufficient for the thioglycolate reaction to complete. Hot wheels after driving cause the gel to dry in seconds, and you end up scrubbing off cleaner residue instead of brake dust. Wait at least 15 minutes between parking and cleaning — this is the cheapest quality improvement you can give yourself.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eCold wheel. 3 minutes. A second pass.\u003c\/h3\u003e\n\u003cp\u003eShake the bottle, open the spray nozzle by twisting, apply the cleaner generously and evenly from 15 to 20 centimeters away to the dry, cold wheel. Start at the bottom and work your way up, because although the gel adheres vertically, it will still run off after some time and runoff marks would dry prematurely. For each wheel, estimate roughly 40 to 60 milliliters — at the upper end for 17-inch wheels with complex spoke fronts, less is sufficient for simple 15-inch steel wheels.\u003c\/p\u003e\n\n\u003cp\u003eAfter 60 to 90 seconds, the color change begins. The full dwell time is 3 minutes, a maximum of 5 minutes — after that, the thioglycolate is saturated and no longer reacts. A common misconception in practice: leaving the cleaner on for 10 minutes does not result in any additional effect.\u003c\/p\u003e\n\n\u003cp\u003eOn the contrary, the gel starts to dry and leaves cleaner residues, which mean extra effort when rinsing. A second short pass on the still-wet wheel is significantly more effective than an extended dwell time on the first — this is the most important operating insight that the manufacturer does not mention on the back.\u003c\/p\u003e\n\n\u003cp\u003eFinally, rinse with a strong stream of water or a pressure washer from top to bottom until no reddish haze runs off. For heavy brake dust on complex spoke structures, a soft \u003ca href=\"\/en\/collections\/felgenreiniger\"\u003ewheel brush\u003c\/a\u003e helps distribute the gel between the spokes — not for scrubbing, but just for touching up and evenly distributing the second layer. In winter, when the ambient temperature is below 10 °C, extend the dwell time generously up to the 5-minute mark, because the reaction speed of thioglycolate decreases with temperature. Conversely, above 25 °C: work shorter and rinse faster before the gel dries.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_sonax-felgenbeast-felgenreiniger_anwendung.png?v=1775901575\" alt=\"Detailing1 application of SONAX FelgenBeast with color change on wheel\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eThioglycolate dissolves iron. Not bitumen.\u003c\/h3\u003e\n\u003cp\u003eOn regular brake dust from road vehicles, WheelBeast works very reliably — that is its core area. The color change also tells you what kind of contamination is present: iron particles react reddish-purple, organic contaminants such as tar, bitumen, or oil do not discolor at all. So after three minutes, you know whether you even have the right tool in your hand, or whether you should switch to an APC or a tar remover instead — a diagnostic step that no acid-based cleaner provides.\u003c\/p\u003e\n\n\u003cp\u003eAs a secondary application, WheelBeast also works as a fallout remover on paint. After parking lots next to railway tracks, industrial areas, or construction sites, fine iron particles from brake dust and rail abrasion accumulate on the hood, roof, and trunk — often not visible to the naked eye, but immediately noticeable as a \"sandy\" feel during the clay bar routine.\u003c\/p\u003e\n\n\u003cp\u003eOn such surfaces, generously spray WheelBeast, wait for the color change, and rinse off within 5 minutes. The clear coat remains untouched as long as you do not exceed the dwell time and the surface was not previously in direct sunlight. In Detailing1 practice, this is the most convenient iron decontamination step before polishing, without an extra product on the shelf.\u003c\/p\u003e\n\n\u003cp\u003eThe clear limitations: burnt-in tar and bitumen stains do not react chemically with thioglycolate — for that, you need a solvent-based tar remover. And with extremely burnt-in brake dust on racing brake systems or after months of neglect, a single pass may reach its limits. If you need material compatibility on all surfaces, stick with WheelBeast and plan for two passes. If you want maximum cleaning power on known robust wheels, the more aggressive \u003ca href=\"\/en\/products\/sonax-profiline-felgenreiniger-felgenreiniger\"\u003eSONAX PROFILINE Wheel Cleaner\u003c\/a\u003e is the better choice for individual cases.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_sonax-felgenbeast-felgenreiniger_ergebnis.png?v=1775901582\" alt=\"Clean Porsche GT3 RS wheel with water beads after SONAX WheelBeast\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eFor the regular caretaker, not for extreme cases.\u003c\/h3\u003e\n\u003cp\u003eWheelBeast is the right choice for anyone who maintains their wheels every one to three weeks and doesn't want to search between three different cleaners in the garage every time they change vehicles. You grab it from the shelf, spray it on, rinse it off — done. This also makes it the logical entry-level product for detailing beginners who have no experience with material compatibility and cannot afford a wrong product choice on polished alloys.\u003c\/p\u003e\n\n\u003cp\u003eWheelBeast is particularly strong in two- or three-car households and in fleet use, where winter steel stands next to summer alloy and OEM diamond cut next to a painted spare wheel. One cleaner for all wheel types means in practice: no risk of mix-ups, no product changes between two cars, no discussion about whether the aggressive alkaline cleaner has now left marks on the chrome edge.\u003c\/p\u003e\n\n\u003cp\u003eHowever, WheelBeast is less suitable if you only clean your vehicle thoroughly once or twice a year and the brake dust has already been baked on for several months. In that case, even a second pass will not remove everything, because iron oxide has already worked its way into the wheel pores and requires mechanical post-processing.\u003c\/p\u003e\n\n\u003cp\u003eFor a complete solution, combine WheelBeast with \u003ca href=\"\/en\/collections\/reifenpflege\"\u003etire care\u003c\/a\u003e as a finish: first chemically decontaminate the wheel, then dress the tire. This is the complete wheel workflow in two steps and under 15 minutes per vehicle — provided you stick with it every two weeks and the brake dust doesn't even get a chance to embed itself.\u003c\/p\u003e\n\n\u003cp\u003eRegarding the choice of container size: The 1-liter spray bottle is the comfortable entry for a single vehicle and comes completely ready to use with an attachable spray nozzle. The 5-liter canister pays off from the second vehicle or at the latest in continuous commercial operation, because the price per liter is noticeably lower and you simply decant the gel into an empty spray bottle. Store frost-free between 5 and 30 °C and use within 24 months of opening — this ensures the color change remains reliably active.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_sonax-felgenbeast-felgenreiniger_lineup.png?v=1775901588\" alt=\"SONAX FelgenBeast 1L spray bottle and 5L canister Detailing1\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e","brand":"SONAX","offers":[{"title":"1000 ml \/ 1 liter","offer_id":49160889925967,"sku":"D1-SNX-04333000","price":11.4,"currency_code":"EUR","in_stock":true},{"title":"5 liters","offer_id":49160889958735,"sku":"D1-SNX-04335000","price":46.16,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/sonax-felgenbeast-felgenreiniger.png?v=1721575164","url":"https:\/\/detailing1.nl\/en\/products\/sonax-felgenbeast-felgenreiniger","provider":"Detailing1","version":"1.0","type":"link"}
