## Questions & Answers

**Q: will this unblock toilet**
A: I believe this product is primarily to unblock bath, sink or shower tray plug holes only.

**Q: Can this be used in outside drains?**
A: Hi, ive checked the bottle & it says it can be used in all pipes & septic systems. On the front of the bottle it says Bathroom. It is very dangerous to wildlife, so you would need to be careful of pets. I only use half a bottle at a time & it does a fantastic job!! Its wonderful if you have a wetroom. Hope this helps!!

**Q: Is this safe to use with a septic tank?**
A: Yes it is but please do not exceed recommended dose.

**Q: Are your products tested on animals? Legally, products made in the UK are not tested on animals, but the cruelty free logo isnt there.**
A: None of our products are tested on animals

### ⭐⭐⭐⭐⭐ Amazing product
*by K***R on 1 February 2026*

Works actreat, I used two bottles in a blocked shower drains, left for 24 hours and rinsed with boiling water, completely gone. No horrible smell, but recommend gloves. Will be keeping a stock of this in the house.

### ⭐⭐⭐⭐⭐ It’s easy to use
*by B***B on 18 January 2026*

I was so happy that bathroom drain unblocked it work so good and the instructions is so easy to follow and good value for money.

### ⭐⭐⭐⭐ First attempt worked well
*by T***E on 8 December 2025*

Only used 1 bottle so far on the hallway bathroom sink but the results were very good. My only gripe is that the bottle says to only leave it to work "for 5 minutes" but suggests that you can leave it longer if needed. I highly recommend ignoring the former and listening to the latter. Just leave it to work overnight. 5 minutes is not long enough.
