Conventional drain cleaners us either acids or caustics to breakdown (FOG), fats, oils and grease in drain lines creating an emulsion that loosens the immediate problem only to move it further down the line. Drain Buster uses microbes and enzymes to digest the FOG into water and carbon dioxide. The thick foam that it generates moves up to 12 feet from the drain cleaning all FOG and food particles from the line and out of any traps. Because of gravity, most drain cleaners cannot remove all of the waste in drains and pipes - Drain Buster can. Conventional drain cleaners contain acids, caustics, surfactants, detergents and emulsifiers. Drain Buster is all-natural, sustainable and biodegradable.
