BuysmartProducts 750ml Green Gone Ready to Use green Algae, Mould and Lichen Killer

Used on slippery stone steps that were slightly green with algae/moss.Works well.Steps aren't slippery any more but I did end up unscrewing the top and using the whole pot on them.

This does the job, I used it on my wooden trellises and a smallwall. My only complaint is that it doesn't go very far, you need a lot of it for it to be effective. I only have a back yard and have had to order another bottle. However, the spray bottle is very convenient and easy to apply to smaller areas, nooks and crannies such as on a trellis. 2nd photo taken 24 hours after the first application, the algae will clear after another one

I used it on my fences and it took all the algae off. Make sure you wear a mask when using as stated on the bottle. Quite strong stuff.

I was sceptical when I bought this but thought I’d try it. I used it on Hartman Amalfi Sun Lounger cushions that had been outside all year including winter and had a heavy coating of green algae on the beige cushions. I’d previously scrubbed them with hot soapy water which worked to some degree but very hard work and not 100% effective. I just sprayed this product on in dry weather and a couple of days later it had all disappeared - amazing stuff !! No scrubbing or wiping - just spray and leave.

Sprayed this chemical on back gate which had turned green, now back to its rightful colour.

I used this for my car around the windows etc. One side always gets green because I don’t use it a lot and one side is next to a wall. I sprayed this on and by next day it was turning black so looks like it was working fine. Unfortunately it also started raining next day and that had an effect on it working to it’s full capacity. All I can say is it did start to work very quickly…but the rain came on for days…I will still use it though.

Didn't work

Yes it’s does remove the green Alge stuff but leaves a white powdery mark which won’t all brush off ????
