Review: Thumbs up from me ! - Excellent. Within hours of spraying my decking and paving slabs , the results were noticeable. The following day - no more green. It was recommended by a friend of my partner, and I was hit and miss wether it would work. No damage to my paint work either. It is a bit expensive , but I work it out at 5 litres will do me 5 years.. therefore £3 ish per year - that's a bargin. Just Spray and forget. Buy it ... You wont be disappointed. However, it wont dissolve or remove dirt, so you will still need to pressure wash, or brush/scrub general dust/dirt away. Big thumbs up ! !

## Questions & Answers

**Q: If I use this to clean a patio that my dogs use as their toilet area will this affect it working**
A: Hi, I wouldn't think that it will affect the cleaning. It's safe to use around pets and plants. I would like to say to use the product on a day that is sunny and no rain is due for the 2 days. Hioe this was helpful.

**Q: Can I use thisto kill moss etc on a bitumen/ felted flat roof with stone chippings on top?**
A: I used it on a sloping felt roof and although it  appeared to kill much of the moss, it proved hard to remove dead moss and it has reappeared over the autumn. so I will reapply in April .

**Q: Is this going to do anything that a pressure washer can’t do?**
A: Yes, it will clean off the algae and other irritants, but it doesn't damage the pointing between the slabs or damage the surface. I used a pressure washer for many years, until I found Simply Spray, and I will not go back to pressure washing, even if I need to repeat the spray twice per year, it is quicker, cleaner and less fussy.

**Q: Can this be used on fences already painted? Concerned it will impact the existing paint under the algae and have to repaint the fence. Thanks.**
A: I used it on mine, it worked within 24 to 36 hours , doesn't look to have had an effect on the paint on fence and it got rid of the algae.

### ⭐⭐⭐⭐⭐ Amazing results!
*by A***M on 6 May 2024*

Firstly, I only ever really leave reviews unless I’m either really impressed, or really disappointed. This stuff is awesome! I mixed it in the 1:4 ratio as it says on the bottle and sprayed it on using a Cuprinol pressurised spray bottle so the actual application was really easy and covered about 15 metres worth of 6ft fence panels. Just to be safe I mixed another lot and went over it again but this time did both sides of my bottom fence as well as all the rest again. I didn’t pay attention to how long it says it takes to work but….ive gone out this morning (the next day) and there is not a single spot of green in sight! I can’t believe how quickly and efficiently it has worked and I’ve still got enough left for another 3 applications so probably another 3 years worth! Very happy with it. What I would say is where the algae was a little bit worse there is a slight grey residue left behind but we’re due thunder this afternoon so I see if a downpour washed it away. Can’t recommend highly enough….lazy gardening is my kind of gardening!
