The Cabin Obsession 32 oz RV Toilet Treatment is the liquid black-tank treatment for RVers who prefer pouring over packets. The 2x ultra-concentrated formula gives 32 treatments per bottle — meaning a single 32 oz bottle handles a full RVing season for most weekend travelers. The easy-measure spout makes dosing predictable without a separate measuring cup.
The Mountain Fresh fragrance covers RV bathroom odors while the live bacteria and enzymes break down solid waste and toilet paper in the black tank. Septic-safe formula won’t damage RV tanks, gray-water systems, or campground septic infrastructure.
Cabin Obsession is an American RV-care brand making septic-safe black-tank treatments in the United States.
