There are different working methods depending on the location of the blockage.

Below you can read the instructions for using HG duo unblocker in the kitchen or the bathroom.

If you have a blockage in the kitchen

First remove as much as of the stagnant water as possible.

Carefully pour 1 measure of drain clog remover (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.

If you have a blockage in the bathroom

First remove as much of the water that no longer drains from the handbasin, shower tray or bath as possible.

Carefully pour 2 measures of the drain unblocker (see measures on the bottle) from bottle A (red bottle) down the blocked drain.

Carefully pour 1 measure (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.
