Precision wheel, rim and brake caliper cleaning.
If you allow brake dust to sit on your wheels for a prolonged period of time, it can eat into the coating (if there is one) and pit the metal. Brake dust is made of an adhesive and carbon fibers that come off the brake pad and tiny metal shavings from the rotor. The intense heat and friction generated by the wheels makes this mixture highly corrosive. Frequent cleaning is the only way to keep your wheels safe and ensure the appearance of the wheel, rim, and brake caliper.
