Buster 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 👍

Good product, does the job well

I tried a few products I already had e.g. using a plunger, bleach, and the known drain products, but nothing seemed to clear my problem. Then I came across Buster's Bathroom Drain Unblocker, used it as instructed and it really worked for my shower drain!! I'm so so happy and ever so thankful. Best believe i'll be repurchasing this item and sticking with Buster forever now :)

Had a blocked shower drain which just would not flow freely no matter what I did. I tried bleach, a drain snake, using a plunger, and that just seemed to make it worse as obviously everything was just bunching up in the pipes. Then I saw this. I followed all the instructions. Left the whole thing overnight and when I ran the shower in the morning everything was sorted. It was wonderful. I had visions of getting in a plumber and having to pull up the flooring, but this was a lifesaver. Have the 2nd bottle in case it needs another dose at some point in the future, but for me this was brilliant. Also delivered next day as Prime.

I have tried numerous different hair unblockers/dissolvers to no avail. Tried this brand and cleared the hair blockage in the bathroom sink in no time only left for around 30 minutes and it cleared it. There is a bit of smell to it and did cover my nose as did make me cough a little. Good value for money compared to what I have spent on other products that havent worked so will always have these in the cupboard. Very easy to use as just take off the lid and pour whole bottle down plug hole.

Delivery was fine and all bottles arrived sealed with no leaks. Hasn't solved my issue but I think it would do better on minor blockages and maybe mine was too far down. It's easy to use, instructions are clear and it doesn't smell overwhelmingly bad. I left it in the bath drain overnight.

Bit expensive but did great job
