Hi William, and welcome!
Dee, Katie makes me do the house wash every spring, so I know what you're talking about. The stuff you buy is expensive, and doesn't work worth a poop! But someone told her once that a pressure washer would "ruin the seals" on her double pane windows, so she refuses to hire the job done.
