Films and Film Care Cleaning Films The great advantage which narrow-gauge film has over 35-mm. is that it will not easily burn, but it may still be easily damaged by heat, and therefore requires just as much care as the highly inflammable stock. Narrow-gauge films are made from a material usually called cellulose acetate, but this describes the base only, and does not include the emulsion, delicately coated on the picture side of the film. The film may also be treated with a special hardening process, and on top of this may receive a coating of protective wax. Films which have been so treated may be used for about 400 shows before being scrapped, but although this is possible very few of them are ever in a fit condition for the 400th show, having been severely mishandled by a series of operators who should have used a little more care, but didn't. The utmost care must be taken of the films in your possession, and at all times you must guard them against the possibility of damage. Never handle them with oily hands, keep them covered to prevent dust from settling on them, and never place them near a radiator or fire. Films which have become dirty or oily may be cleaned with carbon tetrachloride, or with a proper film cleaning-fluid, of which there are several on the market. Saliva should not be used, as it invariably removes the picture ! In cleaning, the film should be passed through a cloth moistened with the cleaning-fluid, but this should be done very slowly to allow the film to dry before being wound onto the spool. 60
