Mr Muscle Probiotic cleaner, Drain Cleaner, Sink Unblocker & Odour Eliminator with Probiotic Cleaning Power, Citrus, 6 x 500 ml

It really works well but didn't follow instructions initially so took me longer to clear blockage but a plunger helped with the excess.

Obviously easy to use you just pour it in, but as for the scent snd actually clearing a blockage forget it, they are rubbish

Vendor was good (description accurate and delivery quick and safely packaged). But product when you look at the small print isn't really designed to clear blocked drains but more to make them smell nice

Use this once a month and it really freshens up my sink use half in downstairs toilet and the other half in the kitchen sink. Good value
