Description:
Camco TST PRO RV Toilet Treatment Drop-INs are multi-chamber pods formulated to help keep RV holding tanks fresher by rapidly breaking down waste and tissue while controlling odors. The bio-enzymatic formula uses enzymes and bacteria to help liquefy waste, with added cellulase enzyme to support paper digestion. Calcium nitrate is included to help address foul odors.
These drop-ins are septic-safe and designed for RV black tank use, with additional cleaning support aimed at breaking down grease, oil, and food debris in grey water tanks. A surfactant blend helps keep solids dispersed and supports working tank sensor probes to help reduce clogs and backups. Designed to work in high temperatures; additional applications may be needed, and the product should be stored below 110°F (43°C). Made in the USA. Pine scent. Includes 10 drop-ins.
