Use one of the following agents for removing printing-ink stains:
Lard or petroleum jelly.—Rub the stain with lard or petroleum jelly;
work it into the cloth. If material is washable, wash with soap and
water; otherwise sponge with carbon tetrachloride, gasoline, or other
grease solvent.
Turpentine.—Soak the stain for a few minutes in turpentine and then
sponge with carbon tetrachloride, alcohol, or other dry-cleaning fluid.
Do not use alcohol on acetate rayon or colored materials.
Kerosene.—To remove printing from flour bags and other bags, soak in
kerosene for several hours. Then wash thoroughly in soap and hot water
and spread on the grass in the sun to dry.
