  • Patent number: 4505001
    Abstract: A flexible tube is suspended from a support arranged to be mounted adjacent a vehicle light surface to be cleaned. The support has an inlet for admitting compressed air to the tube whereby upon selected pressured flow of air through the tube, the tube whips back and forth in a flogging action to clean foreign material from the surface. The support also has an inlet for a cleaning solution used in combination with the whipping tube. The tube has a shape in cross section that tends to maintain it in the plane of the surface being cleaned. In modifications of the invention, a guide is provided to hold the tube in close to the surface being cleaned, and apertures are provided in the tube so that air pressure urges the tube toward the surface.
