One of the following agents may be used in removing iodine stains from unstarched materials:

1. Water. Wash the stain in an abundance of water or soak it for a number of hours in cold water. These stains can be removed also by wetting with water and drying in a warm place, such as over a radiator, repeating this if necessary.

2. Ammonia. Sponge the stain with dilute ammonia.

3. Alcohol. Sponge the stain. This agent frequently can be used on materials which water would injure.

4. Starch, prepared as for laundry purposes; for washable materials. Immerse the stained place in the starch and boil; it first turns blue and then disappears.

5. Flour, used in the same manner as starch.
