Wheel Cleaner

ONLY USE ON COOL WHEELS. Spray on a dry wheel before getting water on the car. Can let sit on the wheel for 5-10 minutes. Spray on green, starts to turn red after a few minutes and looks purple after 5- 10 minutes. Don’t let it sit on the wheel for 15 minutes or longer. You’ll have to reapply the Wheel Cleaner and get it ‘reworking’ again. Works especially well on German autos with the bad break dust. Also, the German cars will make the change in color appear even darker purple. Just the amount of iron in the brake pads.
