Buster Bathroom Drain Unblocker (Pack of 2 x 300ml) | Fast-Acting Sink Unblocker, Dissolves Hair, Sludge & Soap, Drain Cleaner for Shower, Bath and Bathroom Sink Pipes

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.

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.

does a good job , leave it in the system long enough time, then rinse through hot water.

I buy this and apply regularly to the bath to help keep the drain clear and flowing nicely. You can tell it works, as the drainage speed drops when I forget to apply it! Nice and easy to use, just need to go careful when first tipping the bottle up.

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 👍

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.

The blockage was beyond where my bath and washbasin pipes join, so both were blocked. I put a full bottle down the bath plughole and left it for over 8 hours. As the blockage was so bad, I had to boil a full kettle of water about 6 times to pour down the plughole before it shifted. The final kettle-full didn't cause the unblocker to fizz up to the surface, so that's when I knew it had worked. Water drains from bath and basin so fast now. Two more plus points are the subtle lemon scent and the price.

Just brilliant! Used these for a long time, it just gets the job done. Mine is mainly for the shower (clogged hair) plus I leave it for several hours after I’ve had a shower and just it once a month (not all of it) just to keep things running smoothly!!
