Abstract: In an environment in which a transparent glass member, or in which a mirror, is apt to become coated by condensate or water splashes that interfere with clear visibility of an object or image, means are provided for preventing obscuration. A device is provided which includes a continuously flowing film of a transparent, aqueous fluid across the face of the transparent member or mirror. By using a flowing film, no condensate or water splashed on the transparent member or the mirror renders it impossible for use. It is made possible, for example, to shave while taking a hot shower, or to see clearly out of doors through windows that otherwise become cloudy by formation of condensate.
