Power washing house with vinyl siding

[donnamatrix]

Well, even with our extensible ladder, neither of us could get close enough to the soffits at the back of the house, to scrub with a brush or cloth. And now, I certianly won't be using our little electric power washer to do any ... power washing!!! I am thinking maybe using Simple Green, but certainly there are high-up parts of the house that won't be reachable. How can I get them cleaned?

Appreciate everyone's input/feedback.
