Zep Odorless Liquid Bacterial Additive is a new and improved biological waste digester that acts to keep drains and grease traps clear by biologically degrading grease, oil, cellulose, protein, and starch residues. This product`s new low odor formula enables it to work around the clock to maintain drains without the odors normally associated with standard active bacterial drain cleaners. Zep Odorless LBA contains no harsh acids or caustics to damage drains or interfere with the natural bacterial action associated with septic tanks, ponds, and lagoons. The addition of a bacterial culture establishes bacterial colonies that remain in the system, and reactivate each time that waste is introduced. Zep Odorless Liquid Bacterial Additive is a member of the Zep GreenLink line of Environmentally Preferred Products (EPP).
