Bac-Out Drain Care Gel. 

Biokleen Back-out Drain Care gel with gel coating action combines the latest technology of enzymes with natural live cultures for the ultimate drain care and maintenance. Enzymes work to break down grease, fats and other organic matter into a food source the cultures eat and then digest safely into minerals, water and oxygen. This synergistic blend works together, unlike enzyme- only based products, and is crucial in eliminating the source completely for treatment and maintenance of slow drains. Our unique gel formula coats thoroughly- stays longer than powders or liquids. CONTAINS NO: Phosphate, chlorine, ammonia, petroleum solvents, alcohol, butyl, glycol ether, SLS or SLES, EDTA, DEA. No SARA Title III, CA 65, or EPA priority pollutants. No materials listed by the ACGIH as hazardous. CONTAINS: Natural enzyme-producing cultures, citrus extracts, vegetable- and/or sugar-based surfactants, and enzymes. Made in the USA.
