I had the treatment carried out on a very grey looking patio and was wowed by the results. Service was friendly and professional (and involved multiple treatments until the desired effect was achieved. Would not hesitate to recommend.

I am really pleased with cleaning of my patio it looks new.

Didn't remove the black stains despite 3 applications

Website was easy to use, item was delivered promptly.

Fast delivery good product, although it is expensive.

The black spot remover was astonishing successful. It removed all the black spot. It was a little time consuming to apply, leave & wash off but the results were wonderful

It did exactly everything as described so my slabbed area is like new. It did however burn some leaf’s that it came in contact with although not that bad as to kill the plant. The delivery exceeded the delivery date so all in all excellent product and service will not hesitate to use them again.

Great product. Removed all the black spots on my paving slabs and did not damage the surrounding flower beds when I washed it off.

Excellent purchase, great result

Though I'm always a bit cynical about products like this, this worked really well! We had to apply twice to some really bad patches but so happy with how the stones look now, back to new. Coverage was not quite as stated, but that's the same for paint and any product like this. Would use again, and happy to recommend.

Brilliant. Easy order prompt delivery and the product worked like a dream - my patio looks as good as new.

Great result on my stone patio! Impressive results.

Does exactly what it says. Great stuff.

It does what it says been using it for a few years and is good blackspot has never come back that's why it so good

Fantastic product. Easy to apply and wash off. Just a few patches to spot treat as the slabs were completely covered. I can now see the original colour of my sandstone slabs. Have already bought the preventer for next year.

This product is brilliant. Loads of black spots disappeared very quickly. Easy to use and reliable. Very pleased.

Good product but not clear on the advert that requires a pressurised sprayer to apply. This adds significant extra cost to the product which is already expensive. My patio looks much better though

Great stuff

Was ok, it lifted the tiles colour but most of the black spot remains despite several applications and using 2 large bottles

Very impressed with how our patio looks nearly new again
