## Questions & Answers

**Q: How do you open the bottle?**
A: You have to press down on the top whilst turning it. It's like a child lock on medicines.

**Q: Is this product environmentally friendly?**
A: Yes it is and I find it keeps the grey water tank on my motorhome really fresh. It’s not like the trolly grey waste tanks you can easily flush through so the motorhome tank is more stagnant and this product provides the solution

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great for getting rid of drain odours.
*by  on Reviewed in the United Kingdom 23 April 2026*

This stuff is great. I've put a tiny amount down the three plugholes in our motorhome.We travel a couple of times a month, after using this there has been no nasty smells on board.A little goes a long way.Before using this product we used to have a stale drain smell in the cabin, coming up from the waste tank via the plug holes, but not any more.The price reflects the quality and it works well.Only used a couple of times so I feel one bottle will last a long time.Would definitely recommend and will buy again when it eventually runs out.

### ⭐⭐⭐⭐⭐ Worked straight away
