Petroleum jelly and carbon tetrachloride.—If water spots the cloth, work
petroleum jelly or lard into the stain. Then either sponge with carbon
tetrachloride or dip the stained part in a bowl of the solvent. If a
trace of color remains, sponge with denatured alcohol. On acetate rayon
and colored materials, dilute the alcohol—1 cup of denatured alcohol to
2 cups water.
Glycerine, soap, and water.—If the material is washable, first loosen
the stain as above with glycerine or petroleum jelly. Then launder. If
soap or other alkalies are applied before the stain is loosened, they
are apt to set it.
Hydrogen peroxide and sodium perborate.—Sponge with sodium
perborate-hydrogen peroxide mixture (1 teaspoon sodium perborate to 1
pint peroxide). Rinse thoroughly. If the stain persists, sprinkle
powdered sodium perborate on the dampened area and let stand for half an
hour. Finally rinse well. Be sure to test the cloth for colorfastness
before using these bleaches.
