Bio-clean is an environmentally friendly product that works to eat out the waste that accumulates in your pipes. It is a friendly bacterium, and when mixed with the water in your pipes, it begins to eat and digest vegetation and animal waste, producing water that will run harmlessly out of your waste system. After cleaning your system with Bio-clean, add it periodically to keep the system flowing smoothly. Bio-clean is effective, safe, and non-polluting.
