Patio Magic! Concentrate: Ideal for Patios, Paths and Driveways (Kills Algae and Lichens), 5 Litres

Love this patio cleaner. Used on our flagstone patio last month and once again its come up really well. The individual stone colours are back and theres no longer damp, slippery patches. We use this each spring and it lasts the year. Really easy to apply. Just need to be patient as it takes a week or two for noticeable results.

This is really good stuff! I used it on a natural stone entrance which was like a skating rink. I was a bit dubious for the first couple of days then it kicked in! It is still improving weeks later. So easy to use. No smell, no fuss.

Took 3 applications and worked very slowly.My patio was quite dirty, but not black and filthy, but it still took several weeks for it to work.Afterwards my patio looked lovely and clean, and has stayed clean even after the winter.

a good cleaner that works , a local guy wanted £100 to clean my drive this did it , water it on and let it do its work when it rains.

I bought this for my monoblock but didn't read the instructions properly. I think I diluted it too much the first time. I used it again a couple of days later after reading and realising the solution I made was too weak. I used it again a week later and used a much stronger concentration than the second time around. It did work - to an extent- but I don't feel it was that fantastic. I have heard from others how good it is and that is why I bought it. I will not buy another container though as it did not do as good a job as I had hoped.

Amazing product. Did exactly as directed. My before and after photos are only 24 hours apart. I’m astounded in how the algae has literally disappeared without any extra scrubbing or rinsing. 1000% will recommend this product. Not only was it completely affective also a little goes a long way. I used less than half of it for my whole garden.

Wasn’t use and efficient though results take time to be apparent

Really pleased with product, will definitely buy again, lifted algae from block paving a treat.
