Abstract
A method of spraying a mist of cleaning fluid onto the record medium--e.g., motion picture film--and wiping it off, preferably with a soft material such as velvet. Then, the film is dried with air, including thin air jets to spread the liquid evenly, and heated, ionized air. The device has a closed housing and air in the housing is evacuated and sent to a still to recover much of the cleaning liquid and prevent its escape into the atmosphere.
