Dane,
You get a lot of splash-back with this method. You may want to give the rain gear a try.

I think it was Thoreau who warned against having to acquire new clothing for a job? First, I don't own rain gear, and second, us humans are waterproof. Besides, you Northwesterns probably all have rain togs just to live there.
Seriously, when I got my power washer last year, I was cleaning the deck, and made some nice grooves in a teak table, so you do have to be careful. I would have signed the top of the table, but my the wife would have killed me.
