The wheel cleaner that I have always loved has become bigger and better. The new Sonax Wheel Cleaner Plus is 20% stronger than the previous formula for faster and more effective removal of stubborn brake dust and road dirt. Sonax Wheel Cleaner Plus is sprayed transparently and almost immediately turns red when it starts working.

The wheel cleaner from the German company SONAX is designed to remove the toughest dirt such as oil residues, rubber, brake dust, and other road grime from all types of wheels (rims), restoring their original shine, safe on all types of rims, and does not cause corrosion.
