Sensor Power Super Concentrated Sensor Cleaner - Sensor Power is a specially formulated bacterial-enzyme solution 20 times more concentrated than any other Valterra formula. It is designed to restore sensor function in older holding tanks where long-term build-up has caused chronic sensor or level gauge malfunction or in newer tanks where chemical use has caused premature build-up. Sensor Power will safely and effectively clean sensors, tank walls, valves and piping in black and gray tanks, removing all waste, tissue, grease and soap scum build-up. It will withstand heavy exposure to harmful chemicals while eliminating odors, and works even while a vehicle is stationary. Safe for septic systems, dump station and treatment facilities. Contains 2 treatments per bottle. 1 pint per package.
