Zep Drain Bioclean & Odour Control 1L

Seems to have worked well. No more nasty smells and softened the nasty stuff that was in the plughole letting me scrub it clear and clean. I will definitely be buying this again. It's not a drain unblocked, it's a drain cleaner.

Brilliant product. Bought two. One as an urgent drain remedy, one for regular top ups. Smells lovely and lasts.

It appears to work but I’ve only had one application.

Works well

Have tried everything on the market. I work away from home so my drains end up dried out. Used this once and left it on and have came back home for the first time in years without the smell of the drains hitting me when i open the door.Worth every penny.

Did nothing . Purchased alternative options and they worked fine - this on the other hand was a total waste of money

Did a fantastic job. No more smells.

Treated a two bowl kitchen sink, used as described and once all areas were treated including separate draining area, water drained away quickly and has remained so since application about two weeks ago. No strong aroma or messy residue left after use. Would buy again
