Mr MuscleKitchen and Bathroom Odour Eliminator Drain Foamer, 500 ml, Pack of 6

Easy to use and keeps the drain smelling fresh for a good while. Better than anything else I've tried

This stuff does exactly what it says on the bottle. When you notice plugholes starting to drain slowly, usually in the shower, use one of these bad boys. The drain smells nice and fresh again, runs freely and it even removes any limescale around the plughole so that gets left nice and shiny. This is a maintenace product to be used a prevention and cannot be used to clear an actual blockage. The bottle says to use it monthly but that's too expensive so once or twice a year is probably the way forward.

What a wonderful product! I was confused when the box arrived and there were six bottles in there, but upon reading a bottle it states clearly that you are to use one bottle per plug hole! Anyway, leave it for an hour and then rinse with warm water for 30 seconds! Pour it as slowly as you can, the first time I used it I poured at a moderate pace and it began to foam up in my sink bowl: oops!

My drains smell from time to time. (Smell Comes up from the bath) I chuck a bottle of this down and it’s all good for a couple of months. I was a bit disappointed initially when I opened the box though. The box they came in was an old gin delivery box. I thought - how lovely - someone has sent me a few bottles of gin!!

If you've got stinky sewers, this can help. I can longer find it in Tesco or Sainsbury.

Very easy to use and is effective. I would emphasise as other reviewers have that this is a drain cleaner/deodoriser NOT a drain unblocker.

Ive used 3 out of 6 bottles,and the smell is still there,you pour slowly and wait 1h, after that warm/hot water....useless

I have a bathroom that rarely gets used and I used to have to do the pipes with this product every couple of months. There's a product from Hagesan that's granules and it works for much much longer. I would recommend you to choose that instead.
