Unique RV Digest-It’s powerful probiotics go to work, digesting solid waste and sludge build-up inside your holding tanks, preventing backups and clogs.

Thousands of RV Users Already Trust RV Digest-It To Clean And Deodorize Their Holding Tanks.

How RV Digest-It Works

RV Digest-It uses a highly effective blend of bacteria and enzymes that go to work quickly, ensuring that your holding tanks remain clog and odor free. Bacteria needs a food source to survive, and the waste in your holding tanks are the perfect food source for the bacteria in RV Digest-It. Once the bacteria encounter a food source (the waste inside your holding tank), it becomes active and begins to eat. As the bacteria eat, they produce enzymes. These enzymes help to break the waste down into more easily digestible portions for the bacteria so they can completely eat and digest the waste, leaving behind nothing but carbon dioxide and water. The bacteria in RV Digest-It is also specially formulated to force out the bad, odor-creating bacteria (anaerobic) and replace it with good bacteria (aerobic) so sewer odors are eliminated at their source without using any dangerous chemicals, masking agents, or strong fragrances.
