We are a wholesale distributor for Bio-Clean, the safe, dependable, and economical way to keep your plumbing system working at full efficiency. Bio-Clean can renew an entire plumbing and septic system without having to use any harmful and dangerous chemical drain openers. Within an hour after pouring the bacteria into the drain, the bacteria begin to eat their way into the waste that has accumulated on the sides and top of the drain pipe. This is their natural food. They digest the waste and spread throughout your system, cleaning it completely. 2 lb. container as shown.
