Abstract
Abstract The method is one whereby the waste pipelines of dental surgery and similar equipment can be sterilized continuously by exposing each line to the action of a slow-dissolving solid cleansing tablet comprising a sterilizer, a foam inhibitor and solubilizing and emulsifying agents. With such a tablet strategically located, water discharging through the line will dissolve and entrain the various substances continuously, carrying them along the length of the pipeline; in this way, organic matter is denatured and broken up, and the proliferation of microorganisms inhibited.
