To achieve the best results with our Spray-On Car Wash, and to minimize any minute scratching that may occur from serious road grime, dirt, sand, and mud, it's vital you use the proper wipe off cloth. Our high-loft micro fiber cloths are incredibly soft and keep harmful grit away from the paint surface. When you are done, throw them in the wash. Use them over and over again!
