14-19. CLEANING OF FACE MASKS. The disposable masks are designed for one-time use and require no
maintenance. The pilots and co-pilots masks can be cleaned as follows:
a. Remove the microphone from the mask.
b. Remove the sponge rubber discs from the mask turrents. Do not use soap to clean sponge rubber
discs, as this would deteriorate the rubber and give off unpleasant odors. Clean in clear water and squeeze
dry.
c. Wash the rest of the mask with a very mild solution of soap and water.
d. Rinse the mask thoroughly to remove all traces of soap.
c. Make sure the sides of the breathing bag do not stick together while drying, as this may decrease
the life of the rubber in the bag. The mask can be sterilized with a solution of 70 percent ethyl alcohol.
