Rated 5 out of 5 by from Great Product I had used two different products bought at supermarkets, which didn't work, before I bought this product. Put it down sink, left overnight and then poured boiling water down sink - drain ran fine straight afterwards. Very impressed.

Rated 5 out of 5 by from Worked well on blocked bathroom sink I had a blocked bathroom sink, that was most probably blocked with hair. It was so badly blocked the sink would take 10 minutes to empty. I poured the whole bottle contents into the sink and left overnight. By the following morning it was completely unblocked.

Rated 5 out of 5 by from Worked where others failed Tried caustic soda and mr muscle drain cleaners but couldn’t shift the blockage. Even replaced the pipe work but the blockage was under an extension. This was my final resort to getting a plumber out. Pored 2 bottles down then left over night. Bingo! It cleared.

Rated 5 out of 5 by from Shifted fat in an external pipe in 2 hours Don’t bother with the usual product on offer at supermarkets or diy stores. This product is dynamite and fantastic value at circa £7.00 per bottle.

Rated 5 out of 5 by from Fantastic!!! I tried all the bog standard products and still had a blocked sink... I took all the pipework to peices and cleaned it and successfully put it back together and still no joy!! Half a bottle of this and a few hours later... I poured a kettle of hot water down and my blockage was nice and clear... Would definitely use again!!! :-)
