## Questions & Answers

**Q: Does it contain Sulfuric acid?**
A: Not sure but it cleared our drains caused no visual damage

**Q: Is the heat generated from this product safe for the plastic pipework under the sink , last thing i needed is melted pipes**
A: Hi I used it for a kitchen sink blockage and had no issues with melting the plastic pipes . Although it did solve the problem I had I thought that as it was more expensive than the brands you can buy at the supermarket , that it would have worked quicker . Hope this helps .

**Q: Can it be used to unblock a toilet waste pipe ?**
A: I used it to unblock my toilet depending how bad the blockage is. I left it in the toilet over night and it was unblocked the following morning.

### ⭐⭐⭐⭐ 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. Easy to use
