Description
Carefully pour 300 ml of HG liquid drain unblocker in the blocked trap.
Wait about 30 minutes for the substance to work and rinse thoroughly with cold water.
With stubborn blockages rinse through first and then again afterwards with hot water.
If this fails to clear the blockages, repeat the operation or leave the product to work overnight.
Unpleasant odours from sink holes can be effectively got rid of with a few drops of HG liquid drain unblocker.
