BOATLIFE POWDER CLEANER

The Fiberglass Powder Cleaner & Stain Remover from BoatLife is designed to erase a wide range of stubborn blemishes such as rust stains, scuff marks and black streaks. It is nonscratching and ideal for nonskid decks that are notoriously difficult to clean. After a light wash and rinse to remove dust and dirt, let the surface dry. Then use the powder for deep cleaning. It rinses off with fresh or salt water. Follow with a quality protectant wax for a radiant, enduring shine.
