Buster Bathroom Drain Unblocker (Pack of 2 x 300ml) Fast-Acting Sink Unblocker Dissolves Hair, Sludge and Soap, Drain Cleaner Clears Blockages in Shower, Bath and Bathroom Sink Pipes - Made in UK

Such a brilliant item. So easy to use and works brilliantly. As soon as you use this you definitely see how it unblocks everything. It is such a pleasure to use.

Works actreat, I used two bottles in a blocked shower drains, left for 24 hours and rinsed with boiling water, completely gone. No horrible smell, but recommend gloves. Will be keeping a stock of this in the house.

It gives you both a quick option, or an overnight one. The overnight option worked, the short option didn’t.

Had a problem with water not draining for the bathroom sink and tub which are in the same line. It was easy to use and after leaving it for a while to work its magic, it sorted the problem out very quickly. It saved me having to open up areas to check pipes or even have to call a plumber out to check the drain outside the home which the bath pipes lead too. Highly recommend. Can’t say what was causing our blockage but what ever it was, this worked on it. It does have a bad smell but worth it using.

My shower wasn't draining. I applied a full bottle, leaving it overnight which has cleared the blockage right up. This is my new "go to".

I was dubious about this working as the blockage was further along the pipes but left overnight and in the morning totally clear!! Great product 👌

Does not clear completely, but helped me clear blockage, I had to call in a plumber to finish the job.

Only used 1 bottle so far on the hallway bathroom sink but the results were very good. My only gripe is that the bottle says to only leave it to work "for 5 minutes" but suggests that you can leave it longer if needed. I highly recommend ignoring the former and listening to the latter. Just leave it to work overnight. 5 minutes is not long enough.
