POR-15 Marine-Clean cleans and degreases in one application without messy residues, noxious fumes, or flammable solvents. No other cleaner works as fast or as well. It makes petroleum-based cleaners almost obsolete because Marine-Clean can be diluted with water up to 3, 4, 5, or even 10 times its volume, while remaining more potent than other cleaners. Marine-Clean removes grease, oil, mildew, algae, musty odors, soap films, and wax. Use it to clean canvas, vinyl, nylon, holding tanks, grease traps, auto parts, and more.
