Camco RV Toilet Treatment TST MAX Lavender 8×4oz — Formaldehyde-Free, Septic-Safe Odour Control

Camco TST MAX Lavender RV Toilet Treatment is a formaldehyde-free, biodegradable liquid that controls odors and helps break down waste and toilet tissue in RV, marine, and portable holding tanks.

Keep your onboard wastewater system fresh without harsh chemicals: each 4 oz bottle of Camco TST MAX treats up to a 40-gallon holding tank and helps suppress odors for up to seven days. The lavender-scented formula is RV- and marine-approved, septic-safe, and free from formaldehyde, pesticides, and biocides. This eight-pack of convenient single-use bottles is made in the USA and designed for ease of use whether you’re camping, boating, or traveling.

How do I use a single 4 oz bottle in my RV or marine holding tank?

Using Camco TST MAX is straightforward: pour one 4 oz bottle directly into the holding tank or portable toilet after each tank dump or when you begin a trip. The concentrated solution disperses quickly to coat the tank interior and begin breaking down solids and tissue while neutralizing odors.

• Pour one full 4 oz bottle per tank up to 40 gallons
• After dumping, add treatment to an empty tank to maintain freshness
• Safe for frequent use and smaller tanks—adjust dosage proportionally
• Works in portable camping toilets and marine heads

Will this product harm my septic system or RV plumbing?

Camco TST MAX is formulated to be septic-safe and biodegradable, avoiding formaldehyde and other toxic preservatives that can damage systems. It’s designed for compatibility with RV, marine, and portable toilet systems and will not interfere with normal septic processes when used as directed.

• Formaldehyde-free and biodegradable
• No bronopol, pesticides, or biocides included
• Approved for RV and marine use

What kind of scent and longevity can I expect?

The formula carries a fresh lavender fragrance intended to mask unpleasant odors while the active agents work to break down waste. A single treatment helps control tank odors for up to seven days under typical recreational use, reducing the need for frequent tank cleaning between dumps.

• Fresh lavender scent for a pleasant onboard environment
• Controls odors up to seven days per dose under normal conditions
• Concentrated formula reduces number of bottles needed
• Pack of eight single-use bottles for convenience on extended trips
