One Chem Heavy Duty Sink and Drain Unblocker 2 x 750ml - Powerful formula for indoor and outdoor use

Absolutely fantastic clogged drain saver!! I recommend everyone to purchase it .

I never realised that one whole bottle only did one application. So I put one bottle down my outside drain and it was still blocked so I used the other bottle and that did the trick. I don't know how it would work on a sink drain but it does say to use the whole bottle. But it's still cheaper than a plumber so I'm happy.

Good at unblocking sink. But do go careful as it leaked in the bag it was in and seeped through. Make sure you wear gloves and cut the bag open over the bath or sink. Do Not open and take out over a carpet or bathmat as will take the colour out. I had to store one of the bottles in my mop bucket so has not to leak out, even though it's still in a thick plastic bag

Product is OK. But delivery by Hermes was poor. They kept me watiing all day, and then cancelled at about 8 pm. The delivered the next day, fine. But still, one hopes for (and plans) for better service.

It is easy to use, but we have a waste disposal, which tends to block things up every 4 months or so. I usually clear the drains every 3 months as a a preventative, because when it does block, it is usually at an awkward time.I always keep a full bottle in the shed, and replace the one I am using.

Only cleared a little bit used another product and it cleared completely first go wouldn't recommend it

Clear drains

Delivery was prompt. Good job each item was in a plastic bag, as one of the bottles had leaked and the chemical was all in the bottom of the bag.
