White/Yellow Wash ShMITT: Reduce scratches &, maintain that perfect finish wash after wash after wash. Wash with the gentle white foam front. This is the same foam found in the Edge white ultrafine polishing pad. The soft, closed-cell foam sheds dirt, rather than retaining it. Dirty water is able to escape from under the mitt thanks to the convoluted wave surface. Since the dirt is not rubbed into the paint, wash-induced swirls are greatly reduced.
