Biokleen Waste Holding Tank Treatment — 1 Gallon (128 fl oz), Formaldehyde-Free with Michigan Cherry

Biokleen Kleen Waste Holding Tank Treatment is a formaldehyde-free, biodegradable liquid that deodorizes, breaks down waste and tissue, and helps keep RV, boat, and portable restroom holding tanks and lines clean with a fresh Michigan cherry scent.

Designed for recreational vehicles, marine heads and portable sanitation systems, this 1-gallon (128 fl oz) formula works in both black and gray tanks. It combines odor control with biological action to loosen solids and reduce build-up in plumbing and hoses. Because the product is biodegradable and non-aerosol, treated waste is suitable for disposal at dumping stations or compatible septic systems.

How does Kleen Waste remove odors and keep tanks fresh?

Biokleen Kleen Waste uses a blend of biodegradable agents that neutralize unpleasant smells while introducing a pleasant Michigan cherry fragrance. It does not mask odors with overpowering perfumes; instead it helps break down the organic matter that generates odors.

• Formaldehyde-free deodorant action
• Fresh wild Michigan cherry fragrance to replace foul smells
• Neutralizes odor-causing organic compounds rather than simply covering them

Will this treatment work in both black and gray tanks and on boats?

Yes — the formula is effective in black tanks (solid waste) and gray tanks (greywater), as well as marine heads and portable restroom systems. It’s formulated to clean lines, reduce clogs, and break down tissue and solids that accumulate in holding tanks and plumbing.

• Safe for black and gray tank use
• Reduces buildup in hoses, pipes and fittings
• Suitable for RVs, boats, and portable restrooms

Is Kleen Waste safe for septic systems and the environment?

Biokleen Kleen Waste is biodegradable and free from formaldehyde, making it appropriate for emptying into authorized dumping stations and compatible septic systems. Its non-aerosol formula reduces environmental exposure compared with solvent-based or formaldehyde treatments.

• Biodegradable ingredients minimize environmental footprint
• Non-aerosol packaging
• Treated waste is suitable for standard septic and dump systems where allowed

How do I use this treatment to get the best results?

Use the product according to the size of your holding tank and frequency of use: add a measured dose after each use or before storing the vehicle/boat to reduce odors and buildup. Agitate or flush lines as recommended to allow the formula to reach all areas of the tank and plumbing.

• Add recommended dose after each use or before storage
• Flush or run water to move solution through lines and fittings
• Regular use prevents accumulation and reduces the need for deep cleaning

Who is this for? Biokleen Kleen Waste is ideal for RV owners, boaters and operators of portable restrooms who want a formaldehyde-free, biodegradable tank treatment that controls odors, helps break down waste and tissue, and keeps plumbing lines cleaner.
