Drainpipe™ (also called Downpipe™) is a sticky, water-soluble liquid that clings to the inside walls of drains and sinks, neutralising odours from decomposing organic matter or sewage. To apply, pour 1 or 2 dosing caps down the drain (shower, sink or floor drain), followed by a couple of capfuls of water.
It is an excellent cleaning supplement for hotels and tourist apartments, ideal for eliminating lingering odours after cleaning.
