Europe's automakers agree when it comes to wheel care!
A 100% acid-free wheel cleaner that's safe for all types of wheels. Recommended by Mercedes, Porsche, BMW, Volvo, VW and Audi to remove brake dust and road grime. This is a water-based non-acidic detergent that provides great cleaning and guarantees not to damage any type of wheel.
P21S Wheel Cleaners are the famous German-made factory approved way to remove corrosive brake dust from alloy wheels. Safe, pH controlled, non-acid, non-lye based formulas are guaranteed not to attack any type of road wheel, braking system or other automotive surface.
While a bit more costly, P21S Wheel Cleaners are significantly cheaper to use over the long run based on the surface safety they offer. Word of P21S's now famous surface safety spread rapidly during the eighties as owners of expensive road wheels found out the hard way that not all wheel cleaners were created alike.
One key advantage P21S Wheel Cleaners is that you don't have to know all about wheel finishes to find your way to the right formula...
Many consumers are tricked by purchasing a cleaner for uncoated cast wheels only to find out that it destroyed a sensitive coating they never knew was there in the first place! When P21S introduced their wheel cleaners in 1984, they believed their competitors' strategy of offering different formula cleaners for different wheel types was a disaster and still believe so today. Simply stated, P21S Wheel Cleaners work safely and effectively on every type of wheel and wheel coating on the market. No guess work required!
