“Brilliant. Had issues with expanding black spot for years. Wish I had spotted this sooner. All black spot gone and the Indian stone flags are as bright as ever been. Have ordered more to do other flagged areas as I am so impressed”
“Second year running that Black spot destroyer has been used on our sandstone flags, and it works very well. Used a watering can to apply it and scrubbed it in on the very black patches. Left it on for 4 hours then jet washed it off. Good result. Will definitely buy again.”
“This is the daddy of path and patio cleaning. It brightens paving practically before your eyes as you spray it on. It also takes the colour out of your clothes and anything else - so make sure you are wearing stuff you don't mind spoiling to do the spraying. Absolutely top notch chemical - already ordered some more.”
