Remover Patio Cleaner for Block Paving, Bricks & Walls - Safely Remove Stains Caused by Black Spots, Restore Natural Colour - Driveway Cleaner - Biodegradable - 4 L

Expensive but works very well.

Cleaned the front drive well. Cleaned all the White fungi very well but not the black spots. When you consider the cost it is debatable if the product is worth it. Note I followed all the instructions to the letter with excellent conditions, yet did not shift any black spots.

I've tried several cheaper products on my block paved drive---they don't work, but Black Spot remover has worked and also restored original colour. Expensive but it works.

Good product but expensive if there is a large area to cover

I used one pack on both my outside terraces. It sprays on really easily, turns a white foamy type of colour which then goes clear as it dries. I was nervous about my hedges and plants, but they have not been affected at all because I followed the instructions- so long as you don't spray in the wind. The photo is a strip test I did with only one application.

Great product, does what it says on the tin.

This product worked a treat on my block paved patio. This product is good at: Removing white and green algae Bringing the stone back to it's original colour Easy to apply with a pneumatic garden pump Remove with a pressure washer This product is not good at: Not drying out and stop working before the 2 hour leaving time has elapsed, even on a dull, dry overcast February day. Cautions: This product has a very strong bleach smell and can be very overwhelming. Cover your shoes and clothing as it will bleach them and does not advise this on the "precautions" on the bottle. If your pet gets it on their paws I would recommend it is washed off before they go into your house or start licking their paws.

Arrived the next day, used it that afternoon and the patio cam up like new. Keep the wife happy for a while....great product.
