METHOD OF CLEANING DRAINS UTILIZING FOAMING COMPOSITION

摘要

A method of substantially removing an organic restriction from a drain pipe by introducing to a drain a cleaning composition which, when activated with water, contacts substantially all the interior surfaces of the pipe to be treated and improves the flow rate of the pipe by at least about 0.7 liters/min. over a 16 hour period. This method is effective for both clogged and slow-running drains.
