I've used the Black Spot Remover on an Indian Sandstone patio, which is around 20-25 years old. Not so much black spots as black slabs, especially in areas that get very little sun.
After 1 application, the patio looks like new, so am going to try it on my block paved drive and front garden.

This is magic! I used it 2 years ago on a patio that was covered with black spots and its still looking immaculate. It was so easy to use, spray it on, wait a few hours and wash off, you can see it working as you wait. The run off didn't affect any of the plants or lawn nearby. The year after I jet washed it and sprayed the preventer on. While its drying I kept the cats off it but once its dry it doesn't bother them or the plants. It isn't the cheapest treatment on the market but it doesn't harm the plants or the cats and it works ~ the patio looks like new so its well worth it.

Absolutely fantastic service and products! We have asked the Patio Black Spot Removal company to clean our Indian limestone patio and it’s just brilliant work. We wish would have done it sooner. The team worked professionally, took care to move the outdoor plants and furniture and put them back and clean after. The results speak for themselves.

First class experience in every way. Lee was simply outstanding. The product has made the patio sparkle - something to be proud of. I also now know how many other services the team can provide and am already booking more work.

This product cleared the black spot completely from our Indian Sandstone path and it was pretty bad to start with. It required more than one application but it’s easy to apply with a sprayer. I would thoroughly recommend this product and consider it is worth the money for the results
