I treated my exterior walls last spring with a product that kills organic growth and doesn’t even need to be rinsed off. Just spray it on and leave it do it’s thing. This is the same wall a year later. I had pressure washed it all a couple years back but it all grew back in a few years.

Was it wet and forget? That stuff is awesome and cleans better than a pressure washer in my opinion since it can get higher and doesn’t streak.
