One Shot Instant Drain Cleaner 10 X 1ltr Fast Action Professional Unblocker

Mind the fumes, heat and discoloration of metals

The One shot is great for unblocking drain waste pipes and sink/bath traps (unblocking for less than 10 min), but should be used only in well ventilated area, as emitting poison-like smell, once touches the water, not to be poured in the toilet pan, as could crack it - the heat it is causing is cracking pans. Also should not be splashed around the waste in stainless steel sinks, as causing discoloration of the metal. Should not be used together with other un-blocking liquids/powders and should NOT be touched, as destroing the skin. Better to be used by proffesional plumbers only, using long sleave rubber gloves and not to be kept in-house, if there are any children around. It is very usefull but dangerous, if not used & stored properly, as mentioned aboveRead full review

OneShot and Hard water area

I live in an area of very hard water and therefore a lot of lime scale soon builds up in waste pipes etc. I use OneShot regularly to keep sink and bath waste pipes clear. I also use this to keep my washing machine drain clear. I have used this product for years and used to buy it locally from the local plumbing suppliers but it is far cheaper on eBay. Highly recommended.Read full review

good value drain cleaner

Fizzes when first put down so be careful - does the job!

It works

This product does what it says on the label. The word of caution; make sure you pour it through the middle of the drain as over a period it can eat into the silicone. This is particularly relevant for wash basins, mine gets clogged as a result of wet shaving.Read full review
