This stuff is great, made the job much easier (quicker) and patio looks like new.

You sorted out my problem and didn’t over-charge me.

Simply excellent and removes black spot as promised.

Great product for removing black spot. Not sure the ongoing annual treatment is necessary but I’m ok with it.

Only partially successful in removing black spots

The Black Spot Removal product almost completely removed all the spots AND restored the original colour of the stone. There are a very few minor black spots remaining after one treatment but these are trivial and will probably go with a second application. The results were much better than I expected and I will certainly recommend this product to my friends.

Haven’t used my latest batch of Patio Black Sport Remover yet (waiting for a break in the weather) but from previous experience, this stuff works like magic. Expensive but worth every penny - restores paving back to looking as good as new.

Excellent product and very helpful customer service

Excellent delivery service for an excellent product

Great product. Black spots removed from porcelain patio tiles after application then jet washed

Does exactly what is says it does, I use it every year as it brings our York stone right back to looking new

Excellent product does exactly what they claim and the device was as good as the products

Fantastic product, did exactly what they said it would do. Will definitely use these products again.

Efficient service. The product is fantastic. It works as advertised.

Great product

Does what it claims.

Does what it says

Fantastic clean patio - Excellent I purchased a 2 litre bottle of the natural stone remover, and it has done exactly what it says on the packaging and the web. I have now purchased a 4l bottle so I can finish the rest. I will definitely recommend this to anyone who has the same problem Kind regards

The product worked very well though I had to go over some areas three times to get rid of all the spots and thank goodness I had a good pressure washer to clear the remains.

I tried on an old concrete bench which I was going to replace sprayed with black spot removal after a couple of hours washed it off it was just like it was new I was amazed going to do my patio now great product will recommend to anybody
