Kitchen Drain Unblocker – Extra Strong Formula – Rapid Action Cleaner & Odour Remover – Removes Blockages Fast – 5 Doses Heavy Duty Problem Solver

This stuff is amazing. Kitchen sink with a shallow drop and two 90 degree bends into the mains pipe. Frequently gets clogged and slow. This time even the auger failed to clear it. The usual OTC stuff (Mr M etc) does zilch. One go with this and its clear - for now (which is all you can ask for). Tip: it only actually cleared in the final phase while running a ton of hot water down, so don't skimp on that.

Good Works strong Cleans up drains

This is really strong stuff and in a couple of routine drain cleaning jobs did the job well, clearing through the blockage Deducted a star as the chemical fumes that come off this are incredibly strong you can't be anywhere near it when this is working

Easy to use. We tried everything else, home remedies and over the counter ones, but none worked. Bought this and it did it! Shifted a lot of the block first time. Left it a while then did it again and got a nice clear quick running sink again. I've bought another one so I have some in if I need it again. Can recommend.

Looked for something to de-grease my kitchen sink pipes as my standard Mr. Muscle working well for all my drains (I am preventive rather than reactive user) doesn't seem to be dealing with that. My sink is not blocked, but seems to be bit slow running from time to time and sometimes when washing machine is on, there is greasy-like waste return. While in product description it says do not use for washing machines and dishwashers - which I had no plan to do, on the product directly it also adds a little sentence 'or in pipes with direct connection to such appliances'. Like who doesn't have one of those two connected in kitchen??? I was scared to use it :(

I'd had a very slow draining kitchen sink for a while. I'd had two or three goes with the drain/sink unblocking liquids you can get in the supermarket but they did nothing and it gradually got worse (I assume because more grease and debris was getting caught in the existing blockage) until it would barely drain at all and my sink was full of gross, greasy water that took hours to drain. Not only did this work, but it worked almost instantly. I put a small amount of boiling water into the plughole followed by some of this stuff (it didn't need much). I left it no more than a minute or two before pouring boiling water slowly down, and the blockage was gone. Be careful, this stuff is corrosive. You can see and hear it working, it will sputter and gives off a horrible smell so make sure you proceed with caution and kids/pets/things you value are out of the way and the room is well ventilated. I'm not sure why this doesn't have more good reviews, it's the best drain unblocker I've ever used.

Awful - complete gimmick. All this does is froth up….. and that’s it. Does absolutely nothing to clear the problem.

I have to say it's one of the best products I've used to unblock my shower drain. I've now bought this multiple times as it's a fix it for all the drains in my bathroom. As a ong hair person my shower drain clochs pretty regularly, It would take me a long time to snake and plunge our shower drain but with this it's quick, easy to use and little to no fuss. Also good for the nasty sludge that grows in the bathroom u bend.
