Hands down, Jays Wheel Cleaner is the quickest and easiest way to clean stubborn brake dust and road grime. Blended with active cleaning agents and high-tech surfactants, weve built a spray-on wheel cleaner that is tough to compete with. Weve designed this formula to have a thick, viscous composition so it clings to the wheel surface while it is working. After a few moments youll notice the formula change to a deep color purple. Thats the active ingredient attacking the bonded metal contaminants. Allow a few moments for Wheel Cleaner to work (really dirty wheels may require some agitation), then rinse clean for a brand new, show room finish
