Removing Mildew
Remove mildew spots from clothing as soon as you discover them. Brush off mold outdoors so mildew spores do not scatter in the house. Sun and air fabrics thoroughly. If mildew spots remain, pretreat them by rubbing detergent into the dampened stain. Launder the items in hot water and chlorine bleach, if safe for fabric, and detergent. Rinse well and dry in the sun. If any stain remains, use lemon juice and salt. Again spread in the sun to bleach. Rinse thoroughly. Chlorine bleach is effective in killing the mildew growth and eliminating the staining. However, it cannot be used on silk, wool or nylon.

Sodium perborate and hydrogen peroxide are mild oxidizing bleaches. Use sodium perborate if the garment contains silk, wool or nylon. However, it is not safe for white silk and wool. Hydrogen peroxide is safe on all fibers and most colors, but be sure to test for colorfastness. Because these bleaches are mild, they are not very effective in removing mildew stains and will not actually kill the fungus.

Take non-washables to the drycleaner; identify the stain.

Remove mildew from leather foods by wiping the surface with diluted alcohol (l cup denatured or rubbing alcohol to l cup water). Dry in a current of air; use a fan for better circulation. If mildew remains, wash with saddle soap, or a soap containing a germicide or fungicide. Wipe with a damp cloth and dry in an airy place. Polish leather shoes and luggage with a good wax dressing.
