## Questions & Answers

**Q: Can I use this on a fibreglass roof?**
A: I use it on everything and it works, not tried on fibreglass but sure it would be fine. I have a white painted house and live by woodland so the walls outside get algae on them and i spray the walls with it in spring and they come back to white so saves painting the walls.

**Q: Will it clean a gravstone**
A: I haven't cleaned a gravestone but I have cleaned my stone birdbath with excellent results.

**Q: what is the active ingredient?I can't seem to find it in the description**
A: 5-10% Lauryl dimethyl benzyl ammonium chloride.
5 - 10% Myristyl dimethyl benzyl ammonium chloride.
1-5% EDTA - Ethylenediaminetetraacetic acid.

If you are non the wiser, look it up on Wikipedia.

**Q: Is the sprayer included**
A: No, the sprayer is not included

### ⭐⭐⭐⭐⭐ Simple to use and effective for outdoor algae
*by B***N on 5 January 2026*

I bought this Spear & Jackson Spray and Leave remover to deal with algae buildup around the house, mainly near the hose and water pipe, as well as on the tarmac drive. Application was straightforward, and it did a good job without needing scrubbing or pressure washing. After leaving it to work, the algae cleared up noticeably and the affected areas looked much cleaner. Nothing fancy here, but it does what it’s meant to do. Useful if you want a low-effort way to deal with algae on outdoor surfaces.
