HG duo unblocker is for unblocking serious blockages in the drain of the kitchen sink or handbasin. You no longer need a plumber! Blockages in the kitchen are caused by grease and food remnants. In the bathroom, they are caused by toothpaste, hair, soap remnants and skin grease. HG duo unblocker is based on a unique 2-component technology that can be used to remedy different types of persistent blockages effectively. It is safe for all drains. Both components are ready to use and do not have to be diluted, which reduces the chance of splashing. The product neither foams nor splashes when you pour it down the drain. In order to remove unpleasant smells from the kitchen or bathroom drain, we recommend HG drain odour remover.

Blockages in the kitchen: First remove as much of the stagnant water from the sink as possible. Carefully pour 1 measure (see measures on the bottle) from bottle A (red bottle) down the blocked drain. Carefully pour 2 measures (see measures on the bottle) from bottle B (purple bottle) down the blocked drain. Leave the product to work for 1 hour. The longer you leave it to work, the greater the chance the blockage will be dissolved properly. If possible, use before going to sleep and leave it to work overnight. Rinse with a liberal amount of water and then carefully pour the remainder of the liquid in bottle A and then the remainder of bottle B down the drain in order to achieve an optimum post-treatment. Leave this to work for 1 hour too and then rinse with plenty of water. Blockage in the bathroom: First remove as much of the stagnant water from the handbasin, shower tray or bath as possible.
