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

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.

Excellent quality sodium hypochlorite I use to clean my driveway and patio . At a good price ! Excellent seller ! To recommed ! 5 stars !

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.

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

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.

First time using this cleaner always used power washer which I am not a fan of, it is too abrasive and degrades whatever you are cleaning ie patio slabs blocks etc. I diluted to 50/50 and applied with a pump spray bottle left for half an hour with light scrubbing with a stiff broom and washed off with a hose, results were amazing. A lot kinder to your patio slabs without the mess everywhere which you get from jet washing .I am now going to seal with sika patio sealer well worth doing

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

Removed all dirt and algae that had accumulated on the patio and children's toys over the winter with no effort. Rinse patio and make sure all loose debris removed, apply the solution (I used it neat) and gently spread product using a brush. Leave for 30 mins, then rinse. Patio will be as good as when it was first laid. This is a strong alkaline so it will remove the colour from clothes so be careful not to splash on your clothes if you're bothered about them being ruined.
