Grit Guard is a new idea created to save the clear coat and gel coat surfaces you are washing from being scratched. Almost all scratches and swirls which occur, are caused from improper car washing. The dirt and grit from you car get trapped in you mitt or brush as you are washing your vehicle, causing micro marring on our vehicle's finish. Until now, the dirt and grit no way to be released. Now, with the invention of Grit Guard, that has changed. Grit Guard provides the solution you need to release these contaminants. Rubbing your brush or mitt across the Grit Guard Insert releases what has been trapped in the mitt, letting it fall through the insert, into the bottom of the container; not to be picked up again. Your mitt or brushes don't touch the bottom where the contaminates are trapped and you are not repeating the vicious cycle.
