As there are many different kinds of dyes, no one remover will
successfully take out all dye stains. In fact, it may be impossible to
remove some of these stains completely. Proceed as follows:
Water and sunlight.—If the material is washable, rinse the stains in
cold or lukewarm water (soak for 10 to 12 hours if necessary), wash in
heavy soapsuds, and then dry in the sun. Spots on wool or silk materials
sometimes come out by soaking or washing in cold water.
Bleaches.—If a stain remains, try one of the following:
_Hydrosulfite._—Apply one of the hydrosulfites available at drug stores
as a color remover. Follow directions on the package.
_Javelle water._—For stains on uncolored linen, cotton, or rayon, dip in
Javelle water for 1 minute (no longer), remove the chlorine from the
cloth with a sodium thiosulfate solution, rinse well in water. (See p. 6
for more detailed instructions.) Do not use Javelle water to remove
stains from silk or wool.
_Hydrogen peroxide._—For stains on any white material, add a few drops
of ammonia water to hydrogen peroxide. Soak the stains until they
disappear and rinse thoroughly in water. One teaspoon sodium perborate
added to 1 pint hydrogen peroxide makes a good bleach, but it must be
made fresh, as it soon loses its strength.
