Mr Muscle Drain Unblocker, Sink & Drain Cleaner, Fast Acting Heavy Duty Gel Formula, Dissolves Clogs, Works 3x Better Than Bleach, Safe for All Pipes, Duo Pack (2 x 500ml)

This stuff works. I used it on a slow-draining bathroom sink that had gradually turned into a stagnant, smelly puddle over a few weeks (teenager + hair + toothpaste = disaster). I poured in the gel, waited the 5–10 minutes as instructed, and ran hot water through — completely cleared on the first try. You could actually hear the satisfying "glug" as it drained properly again!The gel is thick enough to cut through standing water and stick to where it needs to act — unlike some runnier ones I've tried in the past. Easy to use, no tools or faff required, and the instructions are clear and simple. The scent is that sharp chemical smell you'd expect from a drain unblocker, but it fades quickly and is far preferable to the pong of blocked drains.Worked faster and better than bleach or baking soda/vinegar hacks ever have for me. Good value for a twin pack, especially when used for maintenance as well as emergencies. I’ll be keeping one bottle under each sink from now on.

I’ve been using Mr Muscle Drain Unblocker for a while now, and it’s been a lifesaver when it comes to keeping my sinks and drains clear. The fast-acting heavy-duty gel formula works incredibly well to dissolve clogs, and I’ve noticed it works much quicker than other cleaners I’ve tried in the past. It’s definitely a step up from bleach – it works three times better, as advertised.I appreciate that it’s safe for all types of pipes, which gives me peace of mind while using it. The duo pack with two 500ml bottles is great value and lasts a while. I use it regularly to prevent any build-up, and it’s kept everything running smoothly without any issues.The only minor downside is that it has a strong chemical scent, but that’s typical for this type of product. Overall, I’d highly recommend Mr Muscle Drain Unblocker to anyone who needs a reliable and effective solution for clogged drains!

Bought during Black Friday it worked on my drain in my bath just half a bottle did it, when I shower I don't have a foot bath now lol, my sink in kitchen one the water goes down a fraction and is stinky making me think there's gunk in it, only one owner has been in this house as it's a new build, it could be something stuck down there? It was completed just after Covid, so used the other half in the kitchen so it hasn't worked so much there, I'm thinking sticks you put down once a month so smells see them everywhere . I never put enough in kitchen I think as I thought I it would be the same as bath drain. It's a newly built house during Covid but the stink has always been there since I moved in so could have been the owner before me. I thought it might be the water so I bought a filter that fits in my small fridge freezer and then I bought a years worth of filters as lasts for 60 days which is better for teas coffees and no nasties in the water & in my budget just a idea and was from here. Since I didn't follow the instructions on the bottle to use the whole thing on the sink which may have a stinky blockage. so I'm going to use it all and see if it works.. the bottle is sturdy, was thick m but thick tinlllll enough to go down was satisfying to watch. Once my leg heals as I broke it. I will try the whole bottle next time & edit this review if it works. I didn't mind not having a basin but I do mind my carbon footprint but as I use a scrubber you put dish cleaner in and comes out the sponge. So I got a hamper with a basin full of food from a friend l & still use my sponge thing without using to much dishwasher m and I can fill basin with hot water and just pour it the next day down the drain and hopefully mr muscle & the force of water will work. I read the reviews to keep overnight for better results, and rinse with hot water, very good value for money would buy again for the bath. If it works on the sink then even better as it did get rid of the blockage I don't mind the smell at all. It actually smells nice. I got it next day delivery and so speed was very good. I would have chosen a eco one but sometimes you need the chemicals once in a while. I recycle everything but I'm fussy when it comes to stuff like this. As your buying what you have in your cupboard for things like this. I remember buying paper cat litter and I could have made it myself! Please always look at the eco stuff as if you have time you can do it at home. I use Amazon for heavy things, live I mmmmmmmmm my

Fantastic stuff for the price, clears blockages fast, cleans the pipes well, doesn't smell strong and water drains great after!

Fantastic product, fast working and unblocks anything, great value for money

It’s okay, it does unblock the drain but gets blocked again in a couple weeks

Very effective in clearing the drain on a bathroom sink which was only emptying very slowly. Purchased it because it was a best buy in Which? Following Which?'s suggestions I waited for 10 minutes after pouring the contents of one 500ml bottle down the sink before following up with a kettleful of hot water. Absolutely did the trick and the sink now empties quickly.

Easy to use and does the jobI use monthly to clean kitchen and bath pipes.
