These are caused by cleaning fluid being pushed up into the top edge of the window, or by fluid flowing from under the rubber blade into the dry area of the glass. Using a squeegee for window cleaning may sometimes produce run lines. In 1992, Willie Erken invented the pivoting handle squeegee. If a few spots are missed, a chamois leather cloth works better for touch up than a towel of cloth or paper. Straight strokes, either horizontally or vertically, are normally much more efficient than “fanning” when using fixed handle squeegees however, this method leads to more streaks and missed spots. 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. Simple squeegees are made in various shapes for household use, including the cleaning of shower doors, bathroom tile, and garage floors. Squeegee kits can include a telescoping pole to extend the washer's reach. is still the leader in the squeegee market today. Steccone began a manufacturing process and sold the product in his garage. It was made of lightweight brass with a very flexible and sharp rubber blade. The modern single-blade window cleaning squeegee was patented by Ettore Steccone in 1936, who dubbed it the "New Deal". Changing the blades required the loosening of twelve separate screws. Professional window washers began using the Chicago squeegee, a bulky tool with two heavy pink rubber blades. With the development of the skyscraper in the 20th century, a more efficient tool for the cleaning of window exteriors was needed. (For earlier uses see "floor cleaning" section below.)
This is the earliest written reference to a window cleaning squeegee given by the Oxford English Dictionary. Squeegees were in use for cleaning windows by 1918 when an American book on navy jargon explained that a deck-cleaning tool called a squeegee was "used in civil life to clean windows".
Some squeegees are backed with a sponge which can soak up soapy water from a bucket for application to a dirty window. A soapy solution acts as a lubricant and breaks up the dirt, then the squeegee is used to draw the now water-borne dirt off the glass leaving a clean surface. The best-known of these tools is probably the hand-held window squeegee, used to remove the cleaning fluid or water from a glass surface.
