ADIOS! RV Holding Tank Treatment and Cleaner is a 32oz enzyme-based solution that digests waste, eliminates odors at the source, and safely maintains both black and gray tanks.

Keep your RV, camper or boat sanitary and odor-free with a powerful, non-caustic enzyme formula. This 32oz bottle delivers billions of live bioactive enzymes designed to break down solids, grease, toilet paper and organic residues without harsh chemicals or fumes. It’s formulated for compatibility with plastic, metal and flexible tubing used in most recreational and marine plumbing systems.

How does this treatment stop tank odors?

The product neutralizes smells by biologically digesting the organic matter that causes odors rather than just masking them. Live enzymes break down proteins, fats and carbohydrates so odor-causing residues are reduced over time. Regular use prevents buildup and keeps the tank environment cleaner between pump-outs.

  • Contains billions of digestive enzymes that target organic waste
  • Neutralizes odor at the source instead of covering it up
  • Safe for use in black and gray holding tanks

Can I use ADIOS! in both black and gray tanks and around kids and pets?

Yes — the formula is suitable for both black (toilet) and gray (kitchen/shower) holding tanks. It’s free from caustic chemicals and VOCs, making it safer to use in family environments when directions are followed. Still avoid direct contact and store out of reach of children and pets.

  • Works on both black and gray tanks with a single formula
  • Non-caustic enzymes safe for most piping materials
  • Formulated without harsh VOCs for a gentler scent and environment

How do I use this holding tank treatment for best results?

Use according to tank size and manufacturer guidance: add a measured dose after each pump or as part of a maintenance routine. Allow enzymes time to act—overnight or between trips delivers the best breakdown of solids. For heavy use, increase frequency to prevent buildup and odors.

  • Add recommended dose to tank after flushing or pump-out
  • Let product sit to allow enzymes to break down solids and grease
  • Use routinely for ongoing maintenance and odor control

Will this harm my RV plumbing or the environment?

No—this treatment is formulated to be safe for common RV and marine plumbing materials while targeting organic waste. Because it relies on naturally occurring enzymes rather than corrosive chemicals, it reduces risk of pipe damage and harsh residues. Dispose of tank contents per local regulations to remain environmentally responsible.

  • Safe for plastic, metal and flexible tubing in RVs and boats
  • Enzyme-based, non-corrosive formulation
  • Follow local disposal rules for holding tank contents

Who is this for? ADIOS! RV Holding Tank Treatment and Cleaner (32oz) fits RV owners, boaters and fleet managers who want a professional-strength, easy-to-use maintenance product without harsh chemicals. It’s aimed at families, seasonal travelers and anyone maintaining rental or commercial units who needs reliable odor control, reduced pumping frequency and protection for plumbing systems. For best results, follow dosing directions and integrate the treatment into your regular tank maintenance routine.
