Scrape away as much of the stain as possible with a blunt knife. Then
sponge with cold water. Never use hot water—heat makes egg stains harder
to remove.
Pepsin.—If cold water does not remove the stain completely, sprinkle
pepsin powder over the spot. Work it in well and let stand for half an
hour. Rinse well.
Grease solvents.—For nonwashable materials, sponge first with cold
water. Let dry and then sponge with carbon tetrachloride, gasoline, or
other grease solvent.
