It did reasonabley well but still left a lot still to be removed

Excellent product but rather costly. I used it last year on two areas of patio and neither needed to be cleaned this. I used the product this year on an different patio not previously treated and will have to retreat as I was disappointed with the result.

I liked the ease of use. It made a difference ...i used it three times on some areas . It is very old indian sand stone ... poss 17 years old . The edges are still a bit spotty but it looks much better

The product is amazing. The publicity "before and after" pictures are realistic. I'm astonished how well my patio has come up after two treatments. We came to the house 25 years ago and I've jet-washed it a few times a year but I had no idea that the stones were such a golden colour when really clean. I need sunglasses to walk across the patio, it's so bright!

Problem resolved no fuss and a replacement provided immediately

Great service and the product does what it says.

This is the first product to do what it says on the advertising videos , I have now cleaned my front drive and back garden block paving and the results are amazing it’s back to the original colour and all the lichen and dirt is gone , the product is not cheap but the results make it worth the money , delivery is also very good

Very very disappointing! I purchased the 4 liter patio black spot remover for block paving and applied exactly as the instructions directed. If anything I applied more than the suggested amount and still the black spots have not gone. It feels like £70 wasted. I had hoped spending more money on a product would give me better results but this was not the case.

Company replace product that Had somehow leaked away .

Good product and service. Too expensive and no discount for multiple purchases.

Bought the Black Spot remover a few months ago for a wall and have only today managed to apply the product as there has been so much wet weather. There is definitely immediate results, but I won't know for sure if it has completely eradicated the black spot until I jet wash it tomorrow. So far so good!

Quick and efficient service for delivery of product. All black spots have disappeared,long may this last.

Excellent product, used before Brightens natural stone On this occasion used on red brick wall which was very black in areas … like a new wall now Thank you

After builders had finished, my patio and garden were in a dreadful mess. The Indian Sandstone looked beyond repair. Even the landscaper thought it was impossible to get it back to it's original condition. Installed in 2009, my patio is as good as new, thanks to this fantastic product. Everyone thinks it's a brand new patio.

Good product, easy to use but with a strong smell.

I did the research, including the before/after photos. I expected it to be good, but was very impressed when those photos proved to be absolutely accurate. All my patio etc looks like new arte 7 years of muck. The guy who did it, Brandon, was top class. This is not a cheap product, but it is superb and worth every penny

Worked ok had to reapply

Quick and easy transaction!

A product that lives up to the hype

EXCELLENT PRODUCT, EFFICIENT DELIVERY, VERY HELPFUL SALES SUPPORT
