One Chem - 5L Heavy Duty Patio Cleaner - Path Cleaner Concentrate - Mould Remover, Lichen Remover, Algae Remover - Pressure Washer Detergent - Lichen Control

Great patio cleaner. I diluted it as per the instructions and used a pump-sprayer to apply it to the patio. Made sure it was going to be dry for a day or two afterwards and it has cleaned all the green algae off. Saves doing a pressure wash which always takes ages and makes a mess. Cheaper than the main brand and just as good too.

It dose the job well

Not worth the money don't work

Really good product remove the moss on the patio!

I’m really disappointed with this product. I bought it to help clean my patio which was a mess after the winter months with lots of green, moss and lichen in between the slabs.I diluted it exactly as described and gave it a brush after 20 mins and nothing!So I reapplied it less diluted. Left it for longer, scrubbed it and nothing again!!By this point I was peeved and sprayed it on neat as I had nothing to lose, I left it till the following day this time and still it did absolutely nothing - didn’t even kill the grass after I accidentally sprayed it on that neat.Seriously, don’t waste your money on this product. I could have used bleach and it would likely of turned out better!!I ended up pressure washing the patio and it took just as long as it normally does without using a product.It’s a real shame as I truly thought this was a game changer.

Idel for cleaning patios, diluted the solution in watering can and spread over surface, left over night and jet washed the following morning.Patio clean for another summer.

Ok

cleaned pavers okay but did not tough caravan cover
