Super Cessolve from UTILITY contains four natural bacterial enzymes: protease, which digests proteins such as hair; amylase, which digests starches and sugars such as vegetable matter; lipase to digest fats such as greases and oils; and cellulase to digest cellulose such as toilet paper. It actively continues to make more digesting bacterial enzymes if there is waste in the system. It is suitable for use in drainlines, down pipes and stacks, sinks, grease traps, septic tanks and cesspools, cement vault toilets, recreational vehicles, manure pits and slurry stores, lagoons and ponds, and waste treatment plants. It contains no harmful caustics, acids or solvents, and is nonflammable. It is noncontaminating and harmless to all types of drainpipes. 516-997-6300; www.utilitychemicals.com.
