Mucus
Soak in lukewarm salt water (about 2 cups salt to 1 gallon water) or in weak ammonia water (2 tablespoons ammonia water to each gallon water). Rinse well with cold water and launder as usual.
Mud
Let the mud stain dry, then brush well. Sponge with clear water, or use soap and water if it will not harm the cloth. Sponging with alcohol will help to remove the last traces of the stain. On colored materials and acetate rayon dilute the alcohol—1 cup denatured alcohol to 2 cups water.
Mustard
Glycerine and soap and water.—If the material is washable, work glycerine into the stain, rub lightly between the hands, and then wash the article in soap and water.
Denatured alcohol.—If water spots the cloth, sponge the stain with alcohol. Since alcohol makes some colors run, test a sample of the cloth to be sure it does not harm the color. On acetate rayon sponge with dilute alcohol—1 cup denatured alcohol to 2 cups water.
Bleaches.—Try one of the following, but use sparingly on colored materials and do not use on weighted silks.
Hydrosulfite.—Sponge with a hydrosulfite solution (2 teaspoons in 1 pint of warm water) and rinse quickly.
Oxalic acid.—Apply oxalic acid solution with a medicine dropper (see [p. 7]) and rinse well with clear water. Sponge with weak ammonia water, borax or sodium perborate solution, to neutralize the acid.
