Cleaning of drains – Drainmaster
To clean the shower, basin and kitchen sink traps from hair soap scum and oil apply DRAINMASTER directly into the outlet ( only approx 100ml per application) a reaction will take place with some steam emanating from the outlet, flush with water.
(DRAINMASTER is dangerous please ensure you are wearing protective clothing and do not mess on stainless steel kitchen sinks it will leave marks, also do not apply if the sinks are backed up and there is water standing in the sink)
