Review: Easy to use - Use this regularly, works wonders in the sinks
Review: blocked toilet...This works really well.. - Reviewed Feb 2025: Have had a few instances where the toilet was blocked due to huge logs, and even after 8 hours of bleach, could not move the moser.. After several flushes to make sure the bleach was gone, and no risk of mixing chemicals, I tried this almost in desperation. After a few hours, it had started to breakdown the contents, and after a flush, the whole lot moved and the toilet was back operational again. Much better, and cleaner than a plunger or using the wifes toothbrush to poke it free. Will by again.

### ⭐⭐⭐⭐ Takes longer than standard version
*by J***H on 9 July 2024*

I’ve been relying on Mr Muscle for years to tackle my shower drain which seems to clog pretty often. No other brand works as well in my opinion. I was happy to receive this biodegradable version of the one i usually use to try. Using it is the same as any other drain cleaner - simply pour it down the drain and wait. I will say that it doesn’t work quite as quickly as the standard version. I can’t see it working on the toughest clogs as well either. However, if you’re happy to leave overnight then you’ll get better results. If using products that are better for the environment it’s important to you, you may be happy to take that slight reduction in performance. However, you should be prepared to pay more for it too. If this version was equal in price to the standard version, I would consider purchasing in future.
