FILO Sodium Hypochlorite 20L (4x5L) - High Strength (14-15%) Brick, Driveway & Patio Cleaner | Stain Removal | Algae Control | Bleaching Agent | Odour Removal | Black Spot Removal

Does what it's supposed to do. Excellent. Comes in four handy 5L bottles.

I use this diluted about 1part to five of water on my driveway and decking with a low pressure sprayer. It keeps all the moss and algae down and it's much less messy than a pressure washer - simply spray it on and leave it to work . Be careful with it because it is bleach at the end of the day so wear gloves and wellies, and old clothes you aren't bothered about. Plus it's probably not the best stuff sprayed near plants .

Great product but extremely difficult to take the tops off. Couldn’t use until my son came over and he struggled. But otherwise did the job.

Used this on front garden stone chips as had been discoloured and all black for years, used a ratio of 5 parts product and 1 part water, the chippings are no longer black and back to original colour.Wear protective clothing and a face mask and make sure to apply on a non windy day.

Recommended by a friend, i have always jet washed and spent hours cleaning the patio.I have used the bleach for the first time and my patio is back looking like new after 4 years.

With the changes to the rules relating to the chlorine products it is great to be able to just order this for my spring water supply without paying a fortune.Please keep selling via Amazon

I bought this as it’s advertised in a black 20 litre container it arrived in 4 clear plastic 5 litreContainers, not what I wanted

Cleans patios effectively
