Product details

Product information

The specialists at HG have developed HG duo unblocker specially for the most stubborn blockages caused by grease and food remnants (kitchen drain) or hair, toothpaste, soap remnants or skin grease (sanitary drains). That will save on plumber's bills! After all, HG duo unblocker is based on a unique double component technology with which you can personally tackle the various types of stubborn blockages in a simple and effective manner. Both products are ready for use and need not be diluted, so that there is less chance of splashes. Depending on the blockage in your kitchen or sanitary drain (read the instructions beforehand), carefully pour 1 or 2 doses of bottle A (see markings on bottle) into the blocked drain. Depending on the blockage in your kitchen or sanitary drain, now carefully pour 1 or 2 doses of bottle B (see markings on bottle) into the blocked drain and leave to work for an hour. Rinse well with plenty of water and now carefully pour the rest of bottle A and then the rest of bottle B into the drain for an optimum effect. Leave to work for an hour once again and then rinse with plenty of water.

It worked for us.

We had a partial blockage in our kitchen drainage system and it cleared it. We followed the product’s instructions including leaving it work overnight. We recommend it based on our experience.

Strong stuff

I have used HG products before so know when it comes to cleaning, they are good! This one is no different, you get a lot of product, and its very very strong! I do a lot of cooking and have a very hairy dog who needs showers a lot, so with these two together my kitchen and bath sinkholes are forever getting clogged. I chucked these down the sink, and came back a few hours later (good to leave them to work for a while). Then came back, ran the hot water, and boom the sink holes looked brand new with no clogging. I would be extra careful not to spill any of this on your floor or on nice parts of your bath as it really is strong and will show if you spill it in a wrong place! So in summary, this stuff is strong and will definitely clear your sink!

Unblocked Drains

Wow - this really does unblock drains. The product comes in two separate bottles clearly labelled 'A' and 'B' with premium labels displaying the instructions. It's very easy to use, with clear simple instructions. You simply pour the advised quantity of the solution from bottle A and then the advised quantity from bottle B before leaving it to dwell for the recommended time, you then flush it through with water. I have used it in my shower, it has solved my slow draining problem by breaking down the hair and soap buildup in the drainage pipes. This certainly is a premium cleaning product that does exactly what it says on the bottle. I would highly recommend this product if looking for an effective drain unblocker.

Brilliant product

I bought this product around a month ago. I am really impressed with the results, it was easy to use and it has helped to unblock a sink and a shower. I had tried other products without success. It was reasonably priced so I would definitely buy again.
