In removing writing-ink stains it usually is necessary to try various
methods. Always start with the simplest method and the one least likely
to harm the cloth.
Absorbents.—If the stain is still wet, spread corn meal, salt, French
chalk, cornstarch, or talcum powder on the stain to remove any excess
ink and to keep it from spreading. Work the powder into the stain. Shake
it off as it becomes soiled and repeat the process. When the dry
absorbent fails to take up more ink, make the absorbent into a paste
with water or with a mixture of 1 part water and 1 part alcohol and
apply again. Let dry and brush off.
Glycerine and water or soap and water.—If the material is washable, pour
either glycerine or one of the soapless shampoos on the fresh stain. Rub
lightly between the hands, rinse, and apply glycerine again as long as
any ink comes from the stain. Rinse with clear water. Washing with soap
and warm water will remove some types of ink.
Bleaches.—If the above treatments do not remove the stain, try a bleach.
But use bleaches sparingly on colored materials.
_Oxalic acid._—Soak the stain for a few seconds in a solution of oxalic
acid (3 tablespoons of the crystals of the acid to a pint of water). Or
sponge the stain well with cold water, then stretch the stain over a
bowl of hot water, and apply crystals of oxalic acid directly to the
stain. Rinse by dipping in the hot water and finally in water to which a
few drops of ammonia water have been added. Do not use on weighted silk.
_Hydrosulfite._—Sponge with a hydrosulfite solution and rinse quickly.
