Pencil Marks
Indelible pencil
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.
Lead pencil
A soft eraser sometimes will remove the marks, especially on stiff or starched materials. If the material is washable, rub soapsuds into the stain and launder as usual. Sponge woolen materials with clear water or with a solution of equal parts alcohol and water.
