Our AMAZING Iron, brake dust and rust remover & wheel cleaner. This product dissolves and removes embedded iron particles and environmental fallout from painted surfaces and wheels. This PH balanced, non-acid formula, safely and effectively decontaminates and cleans the surface. You know that it is working to breakdown the iron particles by the chemical reaction that turns it purple. Just spray off and dry. Then seal it up with your favorite quick detailer, like Speedcoat.
