Eco Drain Cleaner from Plumbo - Safe and Effective Probiotic & Enzyme Formula for Mild to Moderate Blockages, Non-Toxic and Eco-Friendly, Breaks Down Grease and Organic Waste, Odour Neutralizer, 1 L

Works well to get rid of hair, soap, residue in shower, sinks, bath. Leave it to work overnight.

Worked slowly, and not particularly aggressively, but got rid of a bunch of slime and gunk in the pipes. Used this when the sink in my motorhome wouldn't drain properly - it has very narrow pipes and weird pipework, because it's a vehicle, and I didn't want to use strong acid or alkali because I don't know how they'll affect the waste water tank. Left this stuff in overnight, and then flushed it through and plunged it again, and it made a good job of clearing out the slimy stuff that grows in pipe bends that never drain. There's quicker, harsher chemicals if you just want to burn through a blockage ASAP, but to keep things running smoothly this seems like a less dangerous option. Probably best used as routine maintenance to reduce build up before it has a chance to clog, rather than emergency unblocker.

Didn't work on our drain but not saying it won't work on yours

2nd purchase. Very good to eliminate.drain smell

Good product: best I have tried.

I am all for eco/natural products and I very much dislike using bleach and similar chemicals, so I thought I’d give this drain cleaner a try.I had a really serious shower drain clog due to a lot of soap build-up since I use a lot of soap bars that tend to not dissolve fully. I didn’t expect that this drain cleaner would work immaculately with one pour since it isn’t that powerful, so once in the morning and once at night, I poured down some of this drain cleaner and I did this for 3 days straight until I used the whole bottle.Turned on the shower head and it seemed like it fixed some of the clog but after 5 minutes my drain went back to clogging again. For using the whole entire bottle I expected it would at least get rid of most of the clogging, so I was kinda disappointed.Although this product didn’t work for me, I’m going to give it the benefit of the doubt and say I had a serious clog and this product is probably better fit for standard maintenance of your drain, rather than a one-time fix.

The instructions do tell you to shake it, but they are written in a font one micron high, and the bit where it tells you to shake it is separated from the bit where it tells you everything else, and I did this last thing at night.The upshot is that I put 300ml down my slowly draining shower waste without shaking, left it for ten hours, and it did absolutely nothing - even less effective than putting Keir Starmer down there. I tested with a bit of toilet paper afterwards and there was still black mould right at the top of the pipe.The next day I shook the bottle vigorously and put 400ml down, left it for 20 hours, and it’s worked.They should put 'Shake well before use' in large friendly letters on the front of the bottle, so you don’t miss it. That still wouldn’t make it smell nice, but I think the bad smell is a fair exchange for not killing all the fish and so forth.

Follow the directions and it does work, definitely leave overnight then pour very hot water from the bathroom sink to avoid the water being too hot and causing hydro shock which could crack the toilet bowl! I would recommend combining this product with tech traders very powerful toilet plunger. Being silicone it's very flexible and can reach much deeper into the toilet bowl. Definitely saves the expense of calling out a plumber!
