Zep Drain Bioclean & Odour Control 1L

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

Used half the bottle as directed and left for six hours. Drain was completely clear. Well worth the money, you get two applications from the bottle.

A brilliant product.

Work very well my draining smell very good

Arrived when stated. Seems to be working, unfortunately with the hot weather our shower trap seems to dry up, which hence makes it smell. So this is a great help.

An enzymic cleaner was recommended so I gave this a try to clean up an outside gully drain which had drain flies. I also used boiling water and a long handled scrubbing brush then used this cleaner afterwards. The drain certainly did get cleaner but what the effect this bioclean had is hard to quantify. I followed all the instructions and left it to work overnight and then scrubbed again the next day. This did nothing to remove the drain flies though. Worth noting that this is much gentler and easier to handle than caustic soda. Perhaps better suited to preventative maintenance cleaning rather than heavy duty single use.

Very impressive

Thank you it has solved my problem in my out side drain. 👍
