This pack includes a 500ml bottle of Ruby Red Wheel Cleaner plus an Alloy Wheel Brush. The Ruby Red neutral pH and user-friendly formulation, gives great wheel cleaning power. It can be used on both Steel and Alloy Wheels. Reacting with the Ferrous Metals contained within brake dust, it attacks those stubborn and hard to remove contaminants, releasing them in a dark red goo. Simply spray on cold wheels and leave to work for 2-3 minutes, then either work in with a wheel brush or rinse away, to leave a great finish.
