This worked really well when the bathroom sink was running slow, the crystals took effect quickly and the water was running well after just one application.

When we moved to our new house the drains were blocked so we bought Mr Muscle drain cleaner crystals to unblock them. The product worked okay after a couple of goes but it didn’t completely solve the problem.

With a household full of young children the last thing I wanted was a house full of chemicals. I was given this product in a welcome to your new house bucket. No thanks

The kitchen drain was completely blocked so I put in the product in as directed and waited.
It amazingly washed the gunk down and I even watched this process with my own eyes. It was good to eventually see all the water go down the drain. It was completely relieving. All works perfect now and I highly recommend.

Easiest way to clean your oven. You do need to follow the instructions carefully though, the fumes need to be avoided and it will burn if it contacts tge skin.

Mr Muscle drank drain cleaner is brilliant for clearing a blocked drain,l use it recently and it worked instantly.A pricey cleaner but it did the job quickly and efficiently.

I followed all the instructions on the jar and when I used the product it had no effect whatsoever in clearing the drain. I could not recommend it at all

This product claims to “dissolve” clogged drains. After following the instructions, and placing 2 table spoons of the gunk down the drain, with the cup of cold water, and waiting 12 minutes…. NOTHING. I tried it two more times.. Infact the damned drain is worse than when I began. This stuff is a total con. Hell I’m mad. They sell this material claiming ” wonder” and being ” industrial strength” and it B.S I tested the powder out side in a cup full of water. There’s no corrosive action, there’s no dissolving agent … there’s clearly no NaOH ( Sodium Hydroxide )… There’s nothing. This is a scam and sham product from Johnson and Johnson.
