Abstract

An apparatus and method for cleaning objects having generally irregular surface features, such as reloadable photographic cameras, has a partial enclosure having opposing side walls, and a top wall joining the opposing side walls. An air ionizing element composed of an ion emitter and an air knife is arranged in the enclosure for electrostatically neutralizing the object with ions entrained in a curtain-like stream of air directed onto the object.
