FILO Sodium Hypochlorite 10L (2X5L) - High Strength (14-15%) Brick, Driveway & Patio Cleaner - | Bleaching Agent | Odour Removal | Black Spot Removal & More.

Brilliant product that cleaned my patio slabs a treat. Also great price.

This product is fantastic! After reading reviews I went with this to clean my patio in the hope it would bring up the worst before jet washing. I didn’t bother to dilute it as instructed as the patio was so bad so I hosed it down first then poured product straight on and it literally came up in seconds. I scrubbed a few areas of need but not too much elbow grease needed then hosed it all off, there was no need to jet wash after! Very pleased!Warning-this Will completely stain any clothes so wear old ones!

Perfect for the job. I used this to spray our outside walls which had become discolored with algae and other grey stuff. The walls look like new, considering they haven't been treated since they were built in 1984.

Great value for cleaning, diluted not so effective but used neat removed stubborn black spots on gard stone

Amazing product worked perfectly stripping black spots off a patio. Downside was both tubs had crushed lids so unscrewing them and breaking the seals were an absolute nightmare.

Bought this primarily for weedkilling. Unlike strong white vinegar this kills the roots too. Bear in mind that, if used on soil, it also makes the ground unsuitable for growing other plants.Mixed this as a 5 parts water 1 part sodium hypochlorite.Weed leaves were dead the same day! See photo.More effective & cheaper alternative to normal weedkiller.

I have attached before and after photos of using this product. And I can't recommend it enough. We had these patches of black mould in the stone and after using this the patio looked like new.We followed the instructions- clean the area , mix this with water , apply on the areas , leaves for 25 mins, scrub a bit and then wash with water.If you have plants nearby , please water them thoroughly before using this product. This is quite strong so would otherwise kill them.

Easy to use. I sprayed it on concrete slabs, left it overnight then hosed it down. It gets rid of the black spots much easier than a pressure washer. It looks great.
