Abstract
A powder formulation containing biodegradable organic compounds which will not bioaccumulate or pollute, allow for the safe and effective room temperature elimination of scale from freshwater and seawater flushed toilets and sanitary waste systems. The formulation mixes readily with water and removes only scales and deposits, not the underlying materials of construction. The formulation is non-toxic, non-caustic, non-flammable, and contains no mineral acids.
