NAB MARINE Black Streak Remover is an environmentally friendly product that was specifically designed as an effective way to remove black streaks and other heavily soiled and stubborn areas on boats and trailers. It is a terrific choice for boat repair and maintenance shops, as well as for boat owners who do their own maintenance and cleaning. NAB MARINE Black Streak Remover is extremely effective at cleaning rubber marks and removing tough debris, while being gentle on surfaces. The product contains no solvents, but yet has aggressive cleaning capabilities. Immediately on application it begins to soften rubber residue. You can simply manually scrub with a brush or sponge and wipe off or rinse off with a hose. It can also be used as a spot treatment, prior to applying one of our NAB MARINE Boat Cleaners or Citrus Bilge Cleaners for a more complete cleaning. It can also be safely used in removing black streaks on RVs, campers, trailers, buses, semi-trucks, etc. NAB MARINE Black Streak Remover is a must-have product for anyone who has black streaks on their boats.
