A windshield wiper scraping device is disclosed with multiple scraping or working surfaces for cleaning ice or other material from the windshield of a vehicle. In the preferred embodiment the scraping device has a composite body comprising two polygonally shaped plate bodies that have planar top and bottom surfaces with a side wall forming the perimeter of the body and joining the top and bottom surfaces. Working edges are formed at the juncture of the side wall with both the told and bottom surfaces. The body is preferably formed of a first plate-like body of rubber and a second plate-like body of plastic. The two bodies are releasably held together by co-operating elements of threaded means. The plastic material is preferably a form of the "LEXAN" material so that it forms a hard semi-rigid working edges on the top while the rubber material is formed of a rubber with the hardness in the range of 70-90 durometers. The resilient edge formed by the rubber has advantages in certain weather over the hard semi-rigid edge formed by the plastic. Preferably the body is formed by two plate-like substances, one of rubber and the other of plastic that can be joined together by chemical or fastener means. The device is sized to be held in the hand and may be pushed or pulled over the windshield of a vehicle. The polygonal shape of the body is preferably either square or octagonal so as to provide multiply working edges during the life of the device.
