Aren't people different. I've never cleaned my patio, just brush it regularly. I'd worry about what all the chemicals were doing to the wildlife, my plants and what happens when it drains off into waterways. Years ago I can't remember anyone cleaning the outdoors.
I checked with the water board, they said it was safe to use Deosan. I use it well diluted, do not use near plants & grass. I also make sure my neighbors know I am using this chemical as it smells of chlorine.
