This product does exactly what it is supposed to and its effects are long lasting. I have used it before and that is why I have bought it this time.

Promises to remove black spot & in our case, on Indian sand stone, it probably removed 90%.

Used this product 3 times now and it's a winner every time. It's best used neat on severe black spot conditions and therefore it won't go as far as it will if diluted. But if you use it neat once, you'll get a great result and if you buy the 4 pack option, you effectively get it at half price. Once you've done that first undiluted (or very lightly diluted 1:1.5) pass, subsequent uses can be further diluted (about 3 water to one pro-kleen) with still great results. I've made it go further by using a small hole rose on my watering can. Also, keep it away from your lawn edges when applying, otherwise it will turn the edge brown, and always wash your watering can thoroughly before using again on your plants. I rate this product very high but follow the care instructions carefully.

I know this is yet another 5 star review, but I do not write many reviews and the Pro-Kleen deserves a mention. It is powerful stuff and works quickly. It will make your patio look (almost) like new. Keep it off any bordering lawn. It will kill pretty well anything growing.
