Is power washing vinyl siding a DIY project for a common sense
individual?

If so, what psi is recommended?
Do you have to keep a "down" spray angle on the sides?
Any special concerns for spraying the soffits?
Do you use liquid cleaners or just plain water?
The majority is vinyl but the facia & trim is vinyl coated aluminum.
Any special problems with this?
