Here’s an interesting story and great pictures of a German firm cleaning the Space Needle in Seattle from KOMO TV news website. “Crews with the cleaning company Karcher GmbH & Co. are only working at night after the restaurant and observation deck close, but they put in a few extra hours on Thursday to allow people to witness the process. Three daring high angle cleaners hit the Needle with water that measured precisely 194 degrees. Even though the sprayers use half the flow of a garden hose, the water shoots out at 3,000 pounds per square inch — more than enough power to send the guy behind the hose flying. It’s a big job with a huge challenge — the crews aren’t using any soap. That’s because what they spray up ends up going down to the Seattle Center and the EMP. Splotches of grime run from the beams under the restaurant all the way down to the base.” Follow the link to see more pictures.
