Egg
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.
