STARBRITE ULTIM F/GLASS STAIN GEL

Ultimate Fiberglass Stain Remover gell formula is formulated to be the most effective way to eliminate tough stains on decks or other fiberglass surfaces. Unlike spray cleaners that drip off before completing the job, the gel clings where applied, completely covering and penetrating into the stain to dissolve it. It removes waterline, fish blood and rust stains without the use of caustic acid or phosphates.
