Due to flammable properties and nylon-damaging substances, cleaning solvents other than
tetrachloroethylene will not be used in the spotcleaning of insertion/extraction equipment.
Tetrachloroethylene will only be used in areas where substantial ventilation is available.
Repeated or prolonged inhalation of the solvent vapors can be detrimental to human health. In
addition, avoid prolonged or repeated contact of the solvent fluid with areas of the skin.
Tetrachloroethylene must not be taken internally.
Cotton item. Spot-clean a cotton item by rubbing the soiled area with a clean cloth dampened with
tetrachloroethylene. Once the foreign substance has been removed, rinse the cleaned area by
repeating the rubbing process with clean portion of the cloth which has been dampened with the
cleaning solvent. Do not wring out the rinsed area if an undue amount of cleaning solvent is
applied. Allow the applicable item to dry thoroughly.
Nylon and rayon items. A soiled nylon or rayon item, except a personnel harness soiled by
airsickness, may be spot-cleaned using the procedures in (a) above.
tetrachloroethylene may be substituted by a solution composed of one-half cup of hand
dishwashing detergent (liquid or powdered) dissolved in one gallon of warm water. A soiled area
cleaned with the soap and water solution will be rinsed with fresh, clean water and allowed to dry
thoroughly. Do not attempt to wring out the material which has been cleaned and rinsed.
When cleaning a personnel harness soiled by airsickness, ensure the water used to wash a
harness is only warm and not hot.
Personnel harness. A personnel harness which has been soiled by airsickness will be cleaned by
immersing the harness in a soap and warm water solution similar to that prescribed in (b) above.
A stiff-bristle brush may be used to remove stubborn foreign deposits by lightly brushing the
affected area(s) during the soaping process. Rinse the cleaned area(s) in fresh, clean water until
the rinse water remains clear, indicating complete removal of soap. Allow the harness to dry
thoroughly without being exposed to direct sunlight or heat which exceed the specifics of
paragraph (f) below.
Plastic and wood items. Spot cleaning of a plastic or wood item will be accomplished by using
procedures in (a) or (b) above, as required. Imperfections on plastic items may be removed by
buffing with crocus cloth. Similar type defects on wood items can be disposed of through use of a
suitable grade sandpaper. When applicable, ensure that the adjacent fabric materials are not
damaged when buffing or sanding.
