Abstract: The window anti-icing/deicing apparatus and method spreads deicing agents onto the outside surface of the windshield and windows of a mobile vehicle and aircraft. The device includes deicing agents, a storage container, power supply, motor, pump, nozzles, and switching system circuitry. The device quickly provides a clear, defrosted window surface on each window prior to the time the vehicle is in motion. The system includes a container connected to a pump or a solenoid for directing the deicing agent to a suction side of the pump through an outlet in to the container. The deicing agent is supplied to a propeller and then via a distributor distributed onto targeted surfaces. Nozzles are provided for expressing the deicing agents onto surfaces. A power supply is connected to the system to operate the pump and the propeller for activating the deicing system. The system may be provided anywhere on a vehicle or an aircraft, such as trunks, roof racks, engine compartments or the like.
