Rated 5 out of 5 by from Excellent gunge Having an annoying blocked waste pipe with access difficult as it runs behind a bath, and my rodding device wouldn’t clear it I looked for a chemical solution. Since this was in stock at Toolstation at a reasonable price and as I recall had some very positive reviews I decided to try it. It was pleasant to use didn’t work as fast as a more aggressive chemical one would but it cleared the blockage. So I bought some more and splashed some down all my sinks.

Rated 4 out of 5 by from Great product . With the name we thought the product would instantly help our blocked drain. It was a slow process but eventually we are on the maintenance phase. Because it is good for the environment it made the difference to why we chose it.
