Tst Holding Tank Chemical 1 Gallon 4 Pack

TST is the first safe waste holding tank freshener combined with the strength of a remarkable concentrated cleaner and lubricant. TST is 100% biodegradable and safe for the environment. Coconut oil soap cleanses the system with an agitating action-thus cleaning waste off the tank walls while coconut oil lubrication keeps it off! The coconut oil soap also lubricates valves and rubber seals to prolong equipment life while it prevents sending units from misreading. Fresh and clean fragrance.
