A hand operated de-icer for cleaning ice and snow from a windshield of a vehicle including a sprayer that forces an antifreeze liquid from its bottle through a heated nozzle onto the windshield. The sprayer includes a pump with a trigger mounted on the bottle that is squeezed by hand to eject the heated liquid. A momentary on switch is also mounted on the trigger so that electrical current passes through the heater element in the nozzle only when the trigger is squeezed. In another embodiment, a second switch in series with a limiting resistor is connected across the momentary switch to apply low heat continually when required. A brush, scraper, sponge or squeegee are interchangeably mounted on the nozzle for brushing away melting ice and snow.
