Stone, Patio and Decking Cleaner | Cleans Stonework, Masonry, Concrete and Brickwork | Protects as well as Cleans | Formulated to Target Dirt, Algae, Moss and Micro-Organisms | 1 litre bottle covers

Having used this product before (for gravestones, no less), I bought some for our old patio slabs. It brought them up a treat, after two treatments, at a slightly higher concentration than 10%. Also cleaned the outside gas meter which is now a glowing pink. Excellent product and value.

easy to mix and apply.would wotk better with jet wash,overall paving was cleaner but not that noticible.

works well

It says on the website what it actually does. Great value.

Mixed as instructions, brushed on patio stones, even rinsed stones after they dried. This product may or may not remove algae or mould but it does not clean normal dirty stones. Used a power washer in the end, gave much better results.

I did follow the instructions for using it but it is not working properly. It does the process only about ten percent for what is need it.

Does what it says on the bottle and does it well,enough said!

Did a good job,but I was expecting dazzling as the paving slabs are under a 13 month old.
