Had a really horrible slimy patch on my drive that the pressure washer couldn't get rid of. Bought this stuff, sprinkled it on, left ot for about 15 minutes then I got down on my hands and knees with a scrubbing brush and five minutes later it was all gone and looking like new again. Excellent stuff and excellent service. Would recommend definitely.

Had absolutely no effect on my patio flag stones. They still look dirty with patterns of some weird growth. I gave them a second treatment with a higher concentration than recommended and again no change. A weak bleach made some improvement but a solution of biological washing powder was significantly better.

Tried this cleaner and I'm impressed, mix in a watering can to the instructions and sprinkle over patio, paths or driveways and leave, over time it cleans. No scrubbing or hard work, just leave.

Great product I used on my old grey patio flags, they have come up like new. Just mix the liquid and wait for it to work. Would highly recommend.

Didn’t do a lot for my patio, left it for 2-5 days. Had to get high powered water on it to clean up any good.
