Penray’s Tough Max multi-purpose cleaning products are formulated to remove grease, oil and grime from tools and parts, as well as for cleaning dirty hands, all while leaving a fresh citrus scent. The noncorrosive Purple variation is suitable for commercial use without fear of pitting or discoloration on nearly any nonporous or semi-porous surfaces, including machinery and tools, as well as floors and walls, tile, porcelain, aluminum, counter tops, wood, vinyl and leather. The products work without water and are solvent-free, will not scratch or harm surfaces, require no rinsing and leave no residue. They are phosphate-free and nonflammable and can be diluted with as much as 95 percent water. The liquid concentrate is available in 32-ounce trigger spray bottles, 5- and 10-gallon pails and a 55-gallon drum.
