Buster Bathroom Drain Unblocker (Pack of 2 x 300ml)

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 👍

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.

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 :)

I had my doubts about this since other products have disappointed in the past. When I applied (full bottle for the shower and full bottle for the toilet sink) I had low expectations for the solution to work. Left it overnight. Next day the drain was actually working. The solution has almost no smell, however, do not get it on your hands since you will be able to smell bleach. The instructions of application were straightforward. I would recommend using the full bottle and let it rest during the night. 10/10 I will buy again.

Bad habits of not using a bath plug have made buying this happen more times than I’d like to admit but that proves how affective it is. It’s not recommended to use this often as it can rode away on the piping system especially if it’s hard plastic. The scent of it is obviously overwhelming therefore I recommend leaving it overnight with a window open. It’s easy to open and use as you just pour it down the drain. I’d always recommend this to someone who either has those bad habits or has a drain that’s always clogging up for whatever reasons.

Takes more than one bottle at a time but if use over a week they do eventually clear the drain. I used them one a day over 3 days and cleared drain

The bath was draining very slowly. I applied this and left it overnight, the next morning voila! All was cleared.
