Do not use water on indelible pencil marks as this spreads the dye and
makes the stain harder to remove. Use one of the following:
Denatured alcohol.—Soak the stain in alcohol. If carbon marks remain,
sponge with soap and water. Do not use alcohol on acetate rayon. Test
all dyed cloth for colorfastness.
Bleaches.—Remove the dye with a bleaching agent.
_Javelle water._—For stains on uncolored cotton, linen, 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 on silk or
wool.
_Hydrogen peroxide and sodium perborate._—For other materials sponge
with a mixture of 1 teaspoon sodium perborate to 1 pint peroxide. Rinse
well.
