Mr Muscle® Power Gel Drain Unblocker cuts through standing water in your clogged drain, dissolving even the toughest clogs. Use this sink unblocker once a week to clear blockages and slow-running drains anywhere in your home, from your kitchen to bathroom sinks. Just pour the entire contents of the bottle down the plughole to attack the blockage directly, and after waiting 5 minutes, flush with hot water (allowing longer for tough clogs). With a formula that clears drains 3x better than bleach*, getting rid of blockages and their unpleasant odours, Mr Muscle® Power Gel is the plughole unblocker that allows you to clean less and live more. *Based on hair removal in laboratory testing.
