Tough on messes, easy on your hands Designed to fit comfortably in your hand, our cube scrubber is a heavy duty, scratch free, sanitary tool for your toughest messes. Tackle baked-on food, stuck-on grime, and anything else with our easy to grip, long lasting sponge. The scrubber material changes with water temperature, becoming soft in hot water for gentle cleaning and scour in cold water for a tougher scrubbing power.
