“Worked really well, had to redo 2places though as black spot didn't clear completely. Patio looks totally different now, the colour is not quite as bright as new but the best it has looked in a few years. Will definitely buy again to do lower patio once I have cleared it and found a way to protect plants from run off.”
“I bought some ultimate black spot destroyer.
I applied it neat on a dry calm day and literally within hours the black marks had all but disappeared.
One flag was particularly bad,so I reapplied solution the following day.
I can safely say that the product works exactly as advertised.
I bought a second lot and will do a before and after video to show the results!”
“natural stone slabs were absolutely covered in black spots, one dose of pro-clean and the slabs are
looking new all the black spots have been removed”
“Wow this stuff is good, quick acting and made my Indian limestone patio like new. Black spots completely vanished. I have raved about this product to work colleagues... they are in the process of buying some for thier patios.”
