Glass windowwiper scrape Techniques
The "swivel method", or "fan method" as it is referred to by professionals, uses a series of strokes combined with turns that hold the water away from the leading edge of the squeegee; when the turn is completed in the opposing direction, there is no water and no dirt left isolated. However straight strokes, either horizontally or vertically are normally much more efficient than "fanning". If a few spots are missed, a chamois leather cloth works better for touch up than a towel of cloth or paper.
This is caused by the squeegee being angled incorrectly forcing the water under the rubber blade out into the dry area of the glass or from solution being pushed up into the top edge of the window. The squeegee should instead be tilted in the direction that the blade is moving across the glass to force to water into the wet area of the glass.
Another method used by window cleaners is to tap the blade on an already wet area of the glass to remove any excess water on the rubber blade. Alternatively the rubber blade can be dried with a towel, although this method is slower and not practical when using extension poles.
According to Guinness World Records, the world's fastest
window cleaner is Terry Burrows of South Ockendon, Essex, England, who cleaned three standard 45-inch × 45-inch office windows set in a frame in 9.24 seconds at the National Exhibition Centre in Birmingham in March 2005. He used an 11.8-inch
squeegee and 2.4 gallons of water.
