How do I get rid of mildew smell in towels?
Why Towels Smell Like Mildew
Mildew smell in towels is usually caused by bacteria and mold that thrive in damp, warm environments. Towels that stay wet for too long, are piled up while damp, or are left in the washing machine after the cycle finishes are prime breeding grounds. Fabric softener and dryer sheets can also contribute by leaving a waxy residue that traps moisture and odor-causing bacteria.
The smell is often a sign that the towels aren't getting fully clean or dry. Regular washing may not kill all the bacteria if the water isn't hot enough or if detergent isn't rinsing out completely.
- Damp towels left in a pile are a common cause.
- Fabric softener can make it worse.
- Front-load washers can harbor mildew.
How to Remove the Smell
Start by washing the towels with hot water and one cup of white vinegar—no detergent. This helps kill bacteria and strip away residue. Run a full cycle. Then wash again with a gentle detergent and hot water. If the smell persists, add half a cup of baking soda to the wash cycle along with detergent. For stubborn cases, use an oxygen-based bleach (like OxiClean) following the package directions.
Avoid using chlorine bleach on colored towels as it can fade them. Also, skip fabric softener and dryer sheets; instead, use wool dryer balls to help fluff and dry towels faster. Make sure towels are completely dry before folding and putting them away.
- Vinegar wash first, then detergent wash.
- Baking soda or oxygen bleach for stubborn odors.
- No fabric softener.
Prevention Tips
After each use, hang towels spread out so they can dry completely. If you have a towel bar, hang them so air can circulate. Wash towels at least once a week, and more often if they stay damp. Clean your washing machine regularly to prevent mildew from spreading to your laundry. If you have a front-load washer, leave the door open between uses and clean the door seal.
- Hang towels to dry after each use.
- Wash weekly.
- Clean your washing machine monthly.
Common mistakes
- Using fabric softener, which coats fibers and traps odors.
- Leaving towels in the washing machine after the cycle ends.
- Washing in cold water, which may not kill odor-causing bacteria.
