Making the patio clean and safe for my elderly dad. Awesome product. The patio hadn't been cleaned in well over 7 years and the black spot came to light after a good karcher. You can see the product as it works. Wish I had taken some before and after photos! Definitely recommend.

Rapid delivery. Very expnsive but it really works
Rapid next day delivery. Very expensive product but worth it.
I used black spot remover on 5 year old cream coloured Indian sandstone badly affected by black spot. I have tried high pressure washing; Patio Magic and hydrogen peroxide, but all of these methods did not touch the black spots. Patio Black Spot Remover not only removed all the black spots but restored the colour of the sandstone.
They claimed that 4 litres treats 20 square meters and I found this to be correct. Therefore at £49.99 for 4 litres, the product is quite costly to treat a typical patio, but in my opinion worth it in view of the excellent results achieved.

Excellent and lasts
This is the only product, over many years and trials, I have found that actually works. Don't expect it to do the work for you, but it has completely rejuvenated our sandstone patio. And a year later, it is still looking like new.

Great Products and all perform very well
The Black Spot Removal Company has a great range of products available for the horrible 'blackspot' which blights our patios, terraces and steps. We have always used the Remover for natural stone, which incidentally has worked wonders on a piece of marble too. Great Stuff.
The Preventor also does what it says on the container!!

I was very sceptical about the before and after photos seen however the jet wash chemicals haven’t touched the black and the black spot on my sandstone patio so I decided to buy this product needless to say it worked exceeded my expectations and I would by again. I only did this a few days ago so I’m not sure how quickly the black spot will return. The application is really easy. He literally pour the liquid into a spray bottle and the spray on the patio. It really is that simple.delivery was within two days.

Great patio cleaner.
Great patio cleaner.
I have used the artificial stone solution for once a year for 3 years and it has transformed horribly blackened slabs back to cream. The slabs stay fairly clean through the winter too.
Easy to apply with a hand pump spray, wait 30 mins and wash away.
Quick delivery from this super helpful company. ⭐️⭐️⭐️⭐️⭐️

Score 8/10
Score 8/10. Good product but takes two to three treatments and even then doesn’t remove the toughest black spots. Coverage limited due to number of passes needed, hence cost high to treat reasonable size patio!

Dear Steven,
Thank you for your review and for sharing your experience.
We're pleased to hear that you found the product effective overall. Some of the more stubborn black spots can require multiple applications depending on the severity and age of the staining. While many patios respond well after one or two treatments, heavily affected areas may need additional applications to achieve the best possible results.
If we can be of any further assistance or you would like to give any feedback on how to improve the service furthermore please contact us directly.
