Jovs Sodium Hypochlorite 14-15% 10 Litre (2 x 5L) – Brick, Driveway & Patio Cleaner - Stain Removal | Bleaching Agent | Odour Removal

This product worked well and cleaned my heavily polluted concrete path fully back to new., clean and bacteria free.I applied it undiluted with a manual pump action sprayer and did not rinse it off but left it to do it’s job. It kept working for weeks.

I use this to clean my driveway and kill the moss , my slabs and brickwork clean up a treat

Amazing product, used on walls of house and totally removed dirt, moss and cleaned brick work up like new.

Bought this after watching professional cleaners cleaning block paving with this chemical in YouTube videos.Our block paving was quite bad, lots of black lichen spots, discoloured blocks and ingrained dirt.First I cleaned the grooves between blocks with a wire brush to remove excess dirt, moss and weeds. Swept up then washed driveway with a Karcher washer using the "t-racer" rotating surface attachment. Waited for drive to dry.Mixed this chemical 3 parts water to 1 part product. Sprayed it onto driveway with a garden sprayer. Left it on driveway to work for 30 minutes then used Karcher washer again to remove it. This time I used our Karchers "dirtblaster" attachment. Which is quite aggressive.About 95% of the black lichen was gone. The discoloration and ingrained dirt had gone and the blocks had become super clean and much brighter.Re-sanded drive by brushing on kiln dried sand twice then sealed the driveway using Screwfix block and concrete sealer which is incredibly cheap but gave excellent results.Driveway now looks amazing. Bright, clean and with a subtle sheen with the sealer
