Highly concentrated blend of detergents, inorganic acids, wetting agents and rinse additives is specifically formulated to keep toilet bowls and urinals sparkling clean. Regular use of Misty Bolex Toilet Bowl and Urinal Cleaner will help to clean traps and sewer lines, aiding in preventing clogs. You can also use it to recondition badly soiled bowls and urinals or for use on fixtures that are not routinely cleaned. By removal of mineral scale, organic matter and stains from bowl and urinal surfaces, the source of offensive odors is usually eliminated. Do not use on porcelain, chrome or other polished metal surfaces.
