It's hateful isn't it? I tried one of the patio cleaner attachments once, the disk with the spinner nozzles inside. Good for stopping back spray but useless for actually cleaning the surface. Back to the small nozzle, getting filthy, aching back
My otherwise perfect wife said to me a couple of years ago that she was concerned that me pressure washing the patio would blast out all the pointing, and suggested that my best option would be to get down on hands and knees with a bucket of water and a scrubbing brush.
I won’t tell you my response, as to do so would result in a lengthy break from the forum.
