Kärcher GmbH & Co. keeps the world’s monuments clean and gains a bunch of free publicity in the bargain. This week the pressure washer manufacturer started a project to spiff up Seattle’s Space Needle by blasting it with hot water. Although the Space Needle was repainted in 1998, it has never had a real cleaning. Kärcher’s rappelling cleaning crew is working during the night so the Needle can stay open and that has resulted in some superb photos of the Needle’s angles with a Seattle cityscape backdrop (scroll down here). The water comes out at 3,000 pounds per square inch and 194 degrees F, ridding the structure of bird droppings and pollution grime. Kärcher’s donated services included everything except the cost of rope technicians from Skala. Some of Kärcher’s other cleaning jobs include Mount Rushmore, the Brandenburg Gate in Berlin, and the National Library in Athens.
