Buster Kitchen Plughole Unblocker (Pack of 3 x 150g) Fast-Acting Sink Unblocker Dissolves Fat, Food & Debris, Drain Cleaner Clears Blockages in Kitchen Sink Pipes - Made in UK

Was fine to use still had to call the plumber in as it was a more serious issue than we thought it was but the product itself worked fine.

This cleared my kitchen sink blockage almost immediately. Very easy to use and far more effective than other unblockers I’ve tried. Great product. Saved a plumber visit.

The bottle does warn that the product will heat up and cause fumes, but you really do have to look for it in the small text. I also didn’t see that you shouldn’t eat or drink around it, so I’d already made a cup of tea just before using the product. There were a lot of visible fumes coming out of the overflow, and the smell is very strong; I had to open the back door because I was really struggling to breathe. As for draining speed, it’s hard to tell as the product is powder and quite a lot remained above the plug hole for some reason. I had to boil the kettle a couple of times to clear the remaining powder. Some of the powder had also solidified, so I’m not sure if that’s normal or not. The plughole itself looks mostly clean, so it appears to have worked, but half hour after having rinsed the product away with kettle water, the smell is still there and I don’t love it. If it’s worked though, then that’s good, I’ll really have to decide if I’ll be using this product again though

Happy with purchase of Buster Kitchen Plughole Unblocker. I have used it as per instructions on the bottle. Good results for the drainage blockage in the kitchen sink and a small bathroom sink. I just used used half bottle each time.

Holy God is this stuff toxic smelling! You MUST have all your windows open for ventilation and have some kind of mask on or tea towel over your face when you pour this down the drain. Anyone elderly or with breathing issues like ashthma would have to be at risk using this. I've never smelled anything like it - I actually had to run out of the room. I am actually surprised this is even sold in the U.K. given how hyper protective they are over all chemical and medical products, yet this brand seems to be the market standard. I'm used to Drano in the U.S. which is nowhere this strong smelling. I am also not convinced this product really gets the job done like Drano. I didn't find my drains flowing that must faster, or the hair balls broken down - I still had to get in there with gloves and remove them by hand, whereas Drano breaks them down for you.

I used this product for first time, but guys it’s working. And the price is very good as well 👍🏻

It worked on my blocked sink unit that had been blocked for years. All other attempts failed.

Okay so I followed instructions and I think there must of been some sort of chemical reaction as my whole flat filled up with chlorine gas... The sink was literally smoking like an old chimney and me and my cat couldn't breathe so had to evacuate for a day. When I came home the smoke / gas was gone but everything now smells of chlorine (the whole flat smells like 1000000000 dirty cat litter trays because of this product) (ammonia smell) the sink was blocked but further back than the U Bend thing so yes amazon nearly killed me for the low price of £3:99 (just hire a plummer so you don't kill yourself with chlorine gas) days on the back it can cause a fire and I feel like it basically did but inside the pipes of my sink. Get a plumber not this.
