Great Post Scott,
You took the words right out of my mouth. Besides all of the above it really is not worth the extra pain. I would just keep using the ladder.
Your work will be much better that way. The only time I would clean windows off with a power washer, it would be to rinse them down after other types of cleaning.
Even then I would probably hit them with a regular cleaning.
Welcome to the board CSL
