On and Off GEL Hull/Bottom Cleaner

MaryKate On and Off Gel Hull and Bottom Cleaner features a thick, fast-acting formula that clings to fiberglass hulls and bottoms to break down tough grease, oil, scum lines, and stubborn rust stains. Its viscous consistency keeps the cleaner in contact with vertical surfaces longer, allowing it to work effectively without immediately running off.

The bold blue-green formula makes it easy to see where the cleaner has been applied, helping provide more complete and controlled coverage during demanding hull-cleaning and restoration projects.
