SOS Hi Heat
Activated Alkaline Red Hot Powdered Drain Opener
SOS Hi Heat contains super-powerful caustic granules activated with aluminum needles. When added to water in a drain or sewer, it releases large amounts of heat and turbulence to liquefy, dissolve and loosen animal and vegetable fats and oils, hair, paper, organic matter and other materials that clog drains and sewer lines.
To clear municipal sewers, use about 20 pounds per manhole. For industrial drains, use 2-3 pounds.
