How to Remove Mildew from Clothes and Towels

Mildew forms on fabric that stays damp too long, like clothes left in the washer or towels in a gym bag. It leaves spots and a musty smell. Acting quickly gives you the best chance of removing it.

Step 1: Brush Off Surface Mildew

Take the item outside and brush off as much mildew as you can with a soft brush, so spores don't spread indoors.

Step 2: Pre-Treat

• Colorfast fabrics: Soak in warm water with oxygen bleach (follow the package directions) for several hours.
• White cotton: Follow the care label. Chlorine bleach may be allowed for white cotton, but never mix it with vinegar.
• Vinegar soak: For a gentler option, soak in a mixture of 1 cup white vinegar per gallon of warm water for an hour.

Step 3: Wash in Hot Water

Wash in the hottest water the care label allows, with detergent. Add 1/2 cup of baking soda to help with odors.

Step 4: Dry in the Sun

Sunlight naturally helps lighten stains and remove odors. Check that stains are gone before using a dryer.

Step 5: Repeat If Needed

Old mildew stains may need several treatments.

Prevent Mildew on Laundry
