Bathroom Drain Unblocker (Pack of 2 x 300ml)

Dealing with slow-draining water in the shower or bathroom basin is a common household nuisance, but this Buster Bathroom Drain Unblocker tackles the problem head-on. Unlike generic multi-purpose unblockers, this thick liquid formula is specifically engineered to dissolve the unique culprits found in bathroom plumbing namely tangled hair, soap scum, and greasy sludge. It pours smoothly down the plughole and clings to the blockage effectively rather than just flushing straight through, actively breaking down the obstruction without damaging the underlying pipes. The application process couldn't be simpler or more fuss-free. For regular maintenance or a slow-running drain, you simply pour the recommended dose directly into the plughole, leave it to work its magic, and then flush it through with plenty of hot water. For particularly stubborn or completely standing-water blockages, leaving it to sit slightly longer completely clears the pipework, allowing water to instantly whirlpool down the drain again with zero backing up. Receiving this product as a handy twin pack offers brilliant long-term value for household maintenance. Having a second bottle stored away in the cupboard means you can instantly treat a secondary bathroom basin or use it as a regular monthly preventative treatment to stop soap scum build-up before it turns into a total blockage. It is an industrial-strength, highly reliable solution that completely eliminates the need for awkward mechanical drain snakes or plunger tools, making it an easy five-star recommendation for keeping your plumbing completely clear.

Bought on spec following positive reviews, and very pleased I did. Cheaper than a certain well known and advertised brand too. We have a relatively shallow drop waste from our shower, and have learned from experience with the old bath how quickly soap and associated grit can build up and restrict outflow. So, at the first sign of waste water slowing, I applied the contents of one bottle as directed and left for around four hours before rinsing through with hot water. Results were excellent, and any restrictions were obviously cleared as the shower now drains very quickly and completely.. I didn’t notice any particular odour with the cleaner and it all rinsed away without leaving any residue. I will buy some more in order to use on a regular, preventative basis 👍

Product is good, it does unblock the kitchen sink but the problem keeps coming back so I tend to buy this product often. It’s the only one I’ve found that works. It’s simple to use and once it does its thing, the water drains away as it should.

I'm very impressed and quite surprised by how well this works! I have had an issue with bathroom drains blocking regularly and often put an unblocker down, which usually marginally helps for about a day and then they go back to normal. This is the first one I have used that has actually cleared them and dramatically improved drainage - I haven't needed to re-do them yet and it has been a month!

Life Saver absolutely brilliant 👏 This Drain Unblocker saved me from a expensive plumber job and the stress of it. My sink was blocked 🚫 no matter what I did I couldn't unblock it. But this worked wonders and cleared it thank you 😊 🙏

Unfortunately, not solve the issue. I consumed the full bottle in the sink and keep it all the night. And in the morning added boiled water but not worked.

I had a slow draining bath it took about 30 minutes to drain fully the shower also was slowly draining but on top of that my bathroom sink was just sitting with water in it all the time which needed scooping out. I bought this product not really having much hope and thought I must of have a major problem as all 3 were showing problems. I got this today and poured a full bottle in the bath plug and shared the other bottle with the sink and shower. I left it about 1 hour and pour kettle water in all plugs. I ran a bath as normal and when finished I drained it away and you could hear the water going down the pipes I tried the sink and that was draining away straight away. Cannot recommend this product enough it’s does exactly what it says it does and saved me 100s on a plumber :-)

This does exactly what it says on the bottle. Pour into your sink plughole, wait 5 minutes, and turn the tap on. BOOM, no more clogging. An excellent product.
