P21S Wheel Cleaner Canister - 1.32 gal (5 liter) - Gel Formula

For wheels that tend to soil heavily due to higher braking speeds, softer brake pads or infrequent cleaning. Spray on, allow to stand up to two hours, touch stubborn spots with a sponge, and rinse off with a sharp stream of water. Gel composition clings to vertical surface to provide increased cleaning effect.
