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

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

I don't want to know how many chemicals are in it, because it works. And at the end of the day that's what you need. Leave in overnight is easy enough.

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.

This is a horrible product that made our drain even more bocked. I thought we were buying a powerful product like Mr Muscle, but this is just a scam.

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

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.

Very pleased with my order and prompt delivery recieved after ordering this product.Thankyou.

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.
