Im a window cleaner and we do a little pressure washing for our customers homes. How do you collect waste water when the water has alread entered the grass? What are some of the tools used if I were to start doing sidewalks and driveways?
We go by each side. Sounds like a combination window with a old wood framed storm window over that right? It can be quite time consuming if those open hard. You may even have to go hourly. We have in the past.
I have never seen a window clean by just a pressure washer. Get out the sqeege and soap cause you're going to need it. The inside windows of resturants are cover with greasy little finger prints that can be difficult to remove. A FINE steel wool pad works wonders.
Its common. My squeege blades dont stick out any further than a 1/8 of an inch. Its a simple fix. Use low lint huck towels or a damp chamois to wipe the edges. I prefer the towels myself. And make sure you have a sharp blade. I change mine out as soon as the edges start to round out.
