If the mask becomes soiled with grease and oil, solvents for these substances, such as kero-
sene or naptha, may be used to remove dirt. However, sprays that are commonly employed in clean-
ing glass windshields must not be used as cleaners, since they contain solvents.
A water solution of nonabrasive soap is recommended for washing grease, oil, or dirt from the
mask. It is then cleansed by rubbing gently with a soft cloth, in a manner similar to cleaning window
glass, rinsing the plastic in clean water, and finally drying.
Scouring cleanser and similar material must not be used in cleaning the mask, since they con-
tain abrasives that scratch the surface.
The use of solvents, such as acetone, ethyl acetate, benzene, and ethylene dichloride to brighten
the surface is never recommended since these substances soften the surface of the plastic.
