Advice for Keeping siding clean?

I have one side of the house that is high do to the slope of the land. It is hard to power wash it. Because of the light color of yellow on the siding it shows dirt and mold growth. And every year I have to power wash the house. Is there a way or something that can be spayed on the siding so that I can just use a hose to get rid of the junk?
