Abstract: An automobile windscreen clearing and cleaning system in which cleaning of the windshield is accomplished primarily by a high velocity, essentially laminar flow of air from a distributed lineal nozzle located adjacent the surface of the windscreen. In one specific emodiment a foil-shaped body of rigid but flexible material is bonded to the outsdie lower surface of the windshield to form a plenum which in turn defines a lineal nozzle from which air is emitted at high velocity to flow up and over the windshield surface for cleaning the windshield surface as well as to create an air curtain. A turbine or other high velocity high pressure air source carried by the vehicle supplies air to the plenum.
