Biokleen Bac-Out Enzymatic Drain Cleaner - 32 Ounce (2 Pack) - Enzyme Prevents Clogs, Eco-Friendly, Live Enzyme-Producing Cultures and Plant Extracts, No Artificial Fragrance or Preservatives

For slow drains and stinky pipes, it's Bac-Out to the rescue. Our unique blend of plant-powered substances uses live enzyme cultures to prevent clogs and remove smelly odors. Bac-Out is proudly manufactured in the U.S. and made with a commitment to people, pets and our planet. How does it work? Bac-Out contains live enzyme cultures that break down clogs into tiny particles. The smaller the particles, the easier it is for Bac-Out’s good bacteria to eat what's clogging the area. Bacteria then digest the particles into carbon dioxide, and the bacteria continues to multiply and eat as long as soil — its food source — is present. This type of enzymatic power allows for continued cleaning of your pipes. If you have any questions, please don't hesitate to reach out."
