“Hi
I purchased some black spot destroyer for my sand stone patio, applied as per instructions and jet washed off but had no effect at all. I re applied a second time but still no bubbling or any reaction at all, then jet washed but still no different the black spots are still there.
I emailed sales twice about this offering pics and videos but they never replied at all, too busy taking money for products that don’t work. If you want to remove black spots look for another product.

“Volatile stuff (even a little bit does kill plants) but it was amazing on my patio, got rid of all the black spots that had been blighting it for years. I wondered if 5 litres would be enough but it was. I used a small hand sprayer and set the spray to fine and gradually covered the slabs with it, they started fizzing almost straight away and within an hour it had done its job. Also used it on some garden pots that have been contaminated, still have some left but I will be buying this again.”
“Very pleased with the black spot patio cleaner we bought. It worked brilliantly and quickly. Easy to use and made a massive difference to our slabs. Definitely recommend.”
