Hydrogen peroxide.—Sponge with hydrogen peroxide or a mixture of 1 teaspoon sodium perborate to 1 pint peroxide. Rinse with water.
Sodium hydrosulfite.—Quickly dip the stain into a sodium hydrosulfite solution (2 teaspoons sodium hydrosulfite to 1 pint water). Rinse immediately. First test the colorfastness of the cloth to this bleach.
Rubber Cement
To remove rubber cement either sponge or dip the cloth in carbon tetrachloride, Stoddard solvent, gasoline, or benzene. If the stain has dried, rub in petroleum jelly or dry-cleaning soap to loosen it. Then apply the carbon tetrachloride or other solvent.
Salad Dressings
The acid of the vinegar or lemon juice in salad dressings may injure the color of the material. Apply a mild alkali such as baking soda or weak ammonia water immediately to restore the color. (See Acids, [p. 10].) Then use one of the following to remove the stain:
Soap and water.—Sponge delicate, washable materials with lukewarm water. Do not use hot water if egg or cream was used in making the salad dressing. Use soap if it will not harm the cloth.
Grease solvents.—Sponge the stain with lukewarm water, let dry, and then sponge with carbon tetrachloride, Stoddard solvent, gasoline, or benzene.
Absorbents.—Absorbent powders are particularly good for splatters of salad oil. Dust cornstarch or talcum powder over the spot, allow it to absorb the oil or grease, then brush off. Or make a thick paste by mixing the powder with carbon tetrachloride or other grease solvent, spread it on the spot, let dry, and brush off. Repeat if necessary. Another method is to put the stained cloth between cleansing tissues and press with a warm iron.
