A squeegee, squilgee or sometimes squimjim, is an onomatopoeically named tool with a flat, smooth rubber blade, used to remove or control the flow of liquid on a flat surface. It is used for cleaning and in printing. The original squilgee was a long-handled, wooden-bladed tool fishermen used to scrape fish blood and scales from their boat deck, and to push water off the deck after it had been washed. 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. 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 perfectly clean surface. Some squeegees are backed with a sponge which can soak up soapy water from a bucket for application to a dirty window. With the development of the skyscraper in the 20th century, a more efficient tool for the cleaning of window exteriors was needed. Professional window washers began using the Chicago squeegee, a bulky tool with two heavy pink rubber blades. Changing the blades required the loosening of twelve separate screws. it was made of lightweight brass with a very flexible and sharp rubber blade. The Ettore Products Co. is still the leader in the squeegee market today.Squeegee kits can include a telescoping pole to extend the washer's reach.
