Usually ethylene glycol, the same as the main ingredient in car anti-freeze. Answer Prior to take-off, airplanes are sprayed with a de-icing agent that melts any ice on the airplane and its wings but it will not re-freeze. Once in the air, many airplanes are equipped with electric heaters or devices that blow heated air over the leading edge of the wings and prevents wate from freezing on it.
