Clean hulls with less effort. Boats left in the water for the season develop stains and scum lines that can be challenging to remove. Our Instant Hull Cleaner was formulated to reduce the labor to remove these stains. This aggressive cleaner applies evenly with a spray bottle (sold separately) and goes right to work dissolving hard to remove stains so that they can be rinsed away with freshwater. Ideal for gelcoated surfaces including hulls, lockers, and baitwells. We recommend using personal protection including gloves, eye protection and skin protection when using this cleaner.
