I left it in the toilet over night and it was unblocked the following morning. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Cleared solid grease buildup *by G***I on 18 July 2026* Customers drain was blocked with a build up of grease, it was solid, tried snaking but that didn’t work, had to treat it twice, but eventually over 2 days it cleared the grease and the wast water pipe drains again, I couldn’t pour boiling water down the pipe I might have got 100ml if I was lucky, but shot it a couple of times and then it all drained away.

Used over night as directed. Unblocked kitchen sink . Easy to use. Worked 👍🏼 ### ⭐⭐⭐⭐ Would recommend *by A***R on 18 April 2026* Although didn't instantly unclog the blocked sink, over the next few days with plenty of hot water being put down, it is running much better now instead of me having to get a jug and empty the water into the washing-up bowl then empty in the bathroom! So dont give up if isn't a "instant magic fix" it does the job eventually.
