Why Swiss roads are a real challenge
Between road salt, brake dust and dirt from the mountain pass – your rims have it tougher in Switzerland than almost anywhere else.
Moisture, differences in altitude and temperature changes leave residues that can become baked on without proper care.
That's why all 21CARS® wheel cleaners are specially optimized for our conditions: They are powerful yet gentle, protect the paint and gloss layer, and can be used without problems even in cold water.
That makes the difference between "clean" and21CARS® clean– visible, tangible, permanent.
