This is amazing .
This is amazing. Scraped off the moss and lichen with a wire brush . Sprayed onto our tiles about 3 hours later I washed it off. They look like new !!!

High expectations with an expensive product
Not had chance to apply yet but quietly confident. At a max 1:1 dilution it is expensive, with some quoting 25:1. High expectations.

Great results
Did a great job on a North facing roof. Delighted with the results.

Works out expensive with a dilution rate of 1:1 so 5 ltrs doesn’t go far.
Doesn’t go far with a 1 to dilution rate so therefore works out expensive and not that effective 7 out of 10 at best. Only suitable for outdoor use due to strong fumes, won’t buy again for a large area

Brilliant product
I would reccomend this for moss and dirty roof tiles. Just spray and let it work. Next thing you will see new looking roof tiles.

Does what it says on the can
Kills the moss straight away on contact. Left for a few days before I cleaned off without too much effort.

Good product that works well. A little expensive.
The product did the job well, if a bit expensive. Got to say the ‘buy two and the second one is half price’ that was advertised did not work. I got charged for two full price packs even after messaging the seller beforehand (and no reply). Good product though. Also used on two low walls with good results. Remember to wear protective gear too.

It does the job but it looks like is just bleach. .. unknown concentration as the labe does not state the content... or I didn't find it.
