## 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

### ⭐⭐⭐⭐ keeps waste water tanks in motorhomes non-smelly
*by L***M on 15 June 2025*

Used for keeping motorhome waste water tanks in good (non smelly) condition. also keeps drain pipes clear of grunge. we use it every tank empty put a few capfuls into sink after emptying waste tank. rinse it down after ten minutes or so then let it slosh about in the tank as we drive. never had an issue so far with smelly drains. recommend. it is quite expensive.
