Live on the river where the summer humidity is stupidly high. I have aTennessee rock slate style walkway to the house. Spent a day last year on my hands and knees scrubbing the moss off with sodium bicarbonate and vinegar. Worked great...until the humidity came back.
I want to use a pressure washer but had a bad experience using it on concrete at my old house. The nozzle pressure was so high and concentrated, all I did was put lines in the concrete. Would this happen to rock/slate?
I don't own a pressure washer so not sure of all of the available attachments to alleviate this problem.
