JOVS Sodium Hypochlorite 5 Litre - High Strength (14-15%) Brick, Driveway & Patio Cleaner - Stain Removal | Bleaching Agent | Odour Removal

After trying all the usual patio cleaners from the likes of B&Q and similar with little success, I came across this stuff.I didn’t hold much hope as nothing had worked to remove the black spots and stains hence why I didn’t take a before photo.This is strong stuff, I applied by decanting a small amount into a bowl and brushing on, left it for an hour then jet washed off. I think the results speak for themselves, my patio looks brand new again.Really easy to use, works incredibly well - 100 recommend.

This is amazing stuff. Killed off all the moss on my tarmac paths. I mixed it 50/50 and used a sprayer to apply. It also did a fantastic job cleaning the patio flags too. I've tried many other products but not comes close to this

This product is absolutely brilliant! It has transformed my black Indian Sandstone slabs back to a lovely milky white colour and all the horrible black spots have all gone. It was so easy to use too. I diluted 2:1 and it worked a treat. I tried many other much more expensive products which were a complete waste of money! With very little effort this has transformed my slabs.

Works reasonably well but works better with extra amount of product per dilution of water, does not remove black spot. Sweep pathway/driveway well before use.

Can dilute but I used straight from container onto very discoloured patio slabs. Brushed over lightly and left for a few minutes. Hosed off to leave amazingly clean as new slabs.

Worked flawlessly mu paths are now clean

Hi 1 of my items had leaked it destroyed the cardboard box and the plastic bag was filling up with the liquid when I got the container out it was only half full

Cleans slabs and paviours brilliantly. Make sure you dilute it and wear full protection
