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

Pros! We have a small bowl sink in our toilet that was constantly getting blocked up, and absolutely nothing else was shifting the build-up. I tried multiple products, but nothing worked until I bought the Buster Bathroom Drain Unblocker.This stuff is incredible. It completely fixed the blockage in just one treatment, dissolving everything that was stuck in the pipes. The sink is draining perfectly now. If you have a stubborn bathroom blockage that refuses to budge, don't waste your money on other brands—this is easily the best one on the market.Cons -genuinely I have no cons. This did the job first time.

To tell you the truth, at first I wasn’t very hopeful that this product would actually unclog my bathroom sink. I had been so busy that I kept putting off dealing with it. Every morning while shaving, I noticed the water was draining very slowly and leaving stains around the sink.I finally ordered this product without expecting too much, but it worked wonders! I left it to work overnight, and by the next morning, the sink was completely unclogged and draining like new. I’m genuinely impressed with the result. Definitely worth trying!

I used this unblocker on a bathroom sink that had been draining slowly for a while. The product is easy to apply — you pour it directly into the plughole and leave it to work. After the recommended time, the water flow improved noticeably without needing to scrub or use any tools. It handled hair and soap build up well, and the drain was running normally again after one treatment. The smell is strong while it’s working, so good ventilation helps. The bottle design makes it simple to pour without spilling.

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.

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.

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

Really impressed with this drain unblocker. Our shower drain was getting badly blocked with hair and the water was taking ages to go down. I used this product and it worked a treat — the water is draining properly again. I bought a pack of three and I’ll definitely buy more. Really good product and well worth it.

Arrived on time, pour it down overnight, and it actually works dissolving hair etc!
