In Portland’s rainy climate, moss and algae grow back within months of a pressure wash because pressure washing doesn’t kill the organism — it just moves it. Soft washing uses professional biodegradable solution that kills algae, moss, and mildew at the cellular level. The clean lasts 18–24 months in Portland with zinc treatment included.
