The TST Line: Purpose-Built for RV and Marine Sanitation

Camco’s TST brand is dedicated entirely to holding tank treatment. The lineup includes liquid formulas, concentrated bottles, and the popular drop-in pod format, giving RVers and boaters the flexibility to choose what works best for their system.

• TST MAX Drop-INs: These drop-ins are specially designed to eliminate odors, break down waste, and ensure top performance in RV and marine tanks. Each Drop-IN treats up to a 40-gallon tank for seven days of odor prevention with just one application.
• TST All-Purpose Liquid: This formula freshens, cleans, and lubricates both gray and black water systems, is 100% biodegradable and safe for the environment, and uses coconut oil soap to cleanse the system with an agitation action while lubricating valves and seals to prolong equipment life.
• TST PRO: The TST PRO features an innovative bio-enzymatic formula positioned as a fast odor stopper and RV sewer waste breakdown solution, available in a Fresh Pine Scent.
