"Left on overnight"

Left on overnight, but sadly didn’t make a difference. Tested on one small area. Did another test area without the product. No difference. Emailed company to tell them but no reply. Our black spot was bad. Might work if not so bad. Shame. I really wanted this to work and would have paid more for a product that did.

Update: I did email, so perhaps it went into spam? I did test one small area in line with instructions and with correct sprayer. Everything was done as instructed. Even spoke on phone to Julie (I think) to confirm we were doing correctly. We did treat twice as well. I’m sorry, but it just didn’t work for us.

"Winning products…"

Have used PBSR products before and they don’t disappoint.
The results are perhaps not as good as they would obtain but I’m happy and I’m not easily pleased

"Brilliant service with a Brilliant…"

Brilliant service with a Brilliant product

"This works brilliantly "

This was the second batch. Ordered 4 litres to see if it worked. It did. Brilliantly. This time we ordered lots and it’s made an incredible difference to our patio and drive which were laid over 15 years ago. They are clean and look like new.

"Absolutely fantastic"

Absolutely fantastic. I was dubious about using this and not optimistic at all. However my old patio looks like new. I have had new steps built using the same paving slabs and the patio that I used the black spot remover on looks as good as the steps. I would highly recommend this to anyone.

" Brilliant Patio Cleaner"

Excellent product which I’ve used for several years…. after trying various other recommendations.
Fast next day delivery.

"Great products"

Great products. I used the Black Spot Remover the first year then in subsequent years I have used the Black Spot Preventer as per instructions. Our Indian Sandstone Patio has no black spot now at all.

A worthy investment.

"Black spot remover a great success. The purchase of the product was easy"

The purchase of the product was easy. The instructions for use were easy to follow. Best of all, the product was simple to apply and our patio is virtually free of black spots and the colour has returned to the stones.

"Stone cleaner"

This product is not cheap but certainly cleaned our york stone path very well and relatively easily.

"Made a great difference to my stone…"

Made a great difference to my stone patio that had bad black spots in places,came up great.
