Product description

Apply Instant Boat Hull Cleaner directly onto stains using a sponge, cloth, or spray bottle. The dual-acid formula works fast—breaking down waterline stains, rust, scum, and tannin buildup on contact.

Safe for fiberglass, gel coat, and painted hulls, it clings to vertical surfaces and penetrates grime without heavy scrubbing.

Let the cleaner sit for 2 minutes

Rinse thoroughly with fresh water.
