Grunt Boat Cleaner efficiently cleans stains from fibreglass and painted boats.

Grunt Boat Cleaner has been specifically designed to make sure that cleaning those nasty stains, from the hull of a boat, is an easy task. Grunt Boat Cleaner penetrates into the gelcoat and a chemical reaction will gently neutralise and absorb the staining, without affecting the gelcoat in any way.
