Patio Black Spot Remover Patio Cleaner for Artificial Stone Paving Slabs – Marshalls, Black Lichen, Green & Red Algae, White Fungi – Restore Natural Colour - Biodegradable 2 L

Amazing product - removed the mould and grime from our patio in one application. It now looks like a new patio

Outstanding stuff. Cleaned the stones VERY well.

First image shows condition of patio before application, second two hours after applying Patio black spot remover and finally after pressure washing. This product is expensive, but gives an exceptional finish and minimises time pressure washing.

Mostly very good. Some areas required a second application

My period was covered with black spot but I know this is expensive if you have a large area to do but it is fantastic all the black spots went abd now each year I put on the presenter to keep the away.

Excellent product and easy to use!

Used this product on my patio and it brought it up as good as when I first laid it . Nothing else I have tried work like this. Not harmful to plants too. Excellent product, would recommend 😀

This product was recommended to me and I am delighted to recommend it in my turn. It has transformed my patio.
