HG algae and mould remover

This really does work, I diluted it so it will last a good while. I had green patches on a wall and sprayed it and two days later it looked fine

Decent product, our patio gets so slippery with algae and surface dirt it's a real hazard. This product makes the surface safe again. I wouldn't say it's the best cleaner as the patio still looks a bit stained, but I will find something else for that. Priority was to get rid of the slipperiness.

I used this to clean up my gran's headstone as my mum and aunt were going to buy a new one and I thought I'd give this a go first. After scrubbing with a brush the headstone looks like it's brand new and has saved my mum and aunt the hassle of getting a whole new headstone.

Why did you choose this product over others?: Works well, better if you do it on a dry spell so it has longer to burn into the algae.

I haven't tried this yet but is was recommended to me by a friend and they told me how good it is so I am looking forward to using it on my patio.

I applied the algae remover diluted to manufacturers suggestion via my watering can sprinkler. It was quite dark green in parts. After 2-3 days it was lighter but still green. So I repeated the process. Have to be sure get 3 dry days in a row. Again better but definitely not gone. Am on 3rd application to date. Also tried it on front path which was lightly affected by moss & algae. Made no difference. Used whole bottle. Will buy something else in the hope it works better. Maybe this stuff is for light areas of algae? Didn’t work for me.

Good product took some time to arrive

Reading the other reviews you wouldn't think this would work well however i used it on my stone flags with good results. Definitely cleaner and has killed the algae . First i treated with ratio as described so 1:20, then i think i used 1:10 for flags with excessive algae. I know i'll have to retreat in 6 months or so but will do nicely for now. also used on a fence but probs needs another spray as it hasnt all cleared..
