FILO Sodium Hypochlorite 5L - High Strength (14-15%) Brick, Driveway & Patio Cleaner - - Stain Removal and Paving Algae Control | Bleaching agent | Odour Remover.

Used this to clean up my patio slabs, brick garden walls and wooden flower beds and it's done an outstanding job. I diluted it 3:2 (3 litres of cleaner to 2 litres of water) and applied it with a sprayer. Could probably have made it weaker than that as it's so effective - the green stains vanish in minutes. Only occured to me to take a photo part way through the clean, but you can see the difference it made in my garden in just a couple of hours. So much cheaper than other brands. I'll definitely be buying this again.

Tried this as a 50/50 dilution with water. It did clean some of the slabs but it wasn't great. Tried it neat and it did a better job. Scrubbing in with a yard brush helps. Did a second spraying ( used a spray bottle to apply) and then used a scoring pad. Came up very good. It's not spray on and wash off and everything is great. It needs a bit of elbow grease but does look great when you've finished.

I put it in a large bucket and added washing up liquid. Dipped the brush in and scrubbed the patio. Left it an hour and washed it off. Did a great job. I would have uploaded pictures but the app wants access to all photos 🤬

Don't usually leave reviews but as I value them so much when trying to trust a purchase I thought on this one I would. We have a drive that is in shade of the garage nearly all day so suffer with moss build up etc. Used this with a sprayer and its been 6 months so far through Autumn and Winter and still looks amazing, nothing has grown back yet, no green etc, a truly top purchase.

My husband was extremely impressed with this product, he has cleaned our brick drive , and patio with it, and it has transformed the drive, the patio is now it’s original colour.

I bought this because it was the best 5l deal when I needed it. There were some 10l deals but it was more than I need for now

I tried to clean the patio past 2 years using patio cleaners and was surprised this product did what it said . I did a pressure wash and used a brush to apply this product on to wet patio and prsuute washed for this result !

It cleans well but be carefully using
