This treatment is highly concentrated, meaning you get long-lasting performance with just a small amount, making it cost-effective in the long run. Its versatility is another plus, as it is safe to use with all types of septic systems and holding tank materials, making it suitable for RVs, boats, and portable toilets.

Its ease of use - simply adding the measured amount to the tank - makes it a hassle-free solution for maintaining your RV's sanitation system.

The Camco TST MAX Camper/RV Toilet Treatment Drop-INs offer a convenient and effective solution for managing your RV's holding tank.
