Was too lazy to pull out the hose for a proper wash, but couldn't stand to look at my brake dust covered wheels so I decided to go to the coin wash. Used the "Tri-color " foam ( no brush) sprayed the entire car and wheels, and was shocked how clean the car came out, especially the wheels which usually require hand washing to get the black dust off. My concern is, if this foam is this strong, what does it do to the finish on the car
