The ScumBuster outer coating (santoprene) is designed to handle most household chemicals and cleansers. Household cleaning agents should not damage your ScumBuster scrubber. Always follow the manufacturer's recommendations when using chemical cleaners such as sprays, foams, rub-on gels, liquid detergents and bleach solutions. Choose non-abrasive all-purpose cleaners for fiberglass, plastic, glass, ceramic surfaces and brass, gold, or chrome fixtures.
