how to remove mildew smell from clothes

There’s nothing worse than pulling clothes out of the laundry or closet only to notice that musty, mildew smell. Mildew odors not only make your garments unpleasant to wear but can also indicate the presence of bacteria or dampness in your storage area.

The good news? You don’t need harsh chemicals or expensive cleaners to fix this. With the right approach and a little patience, you can remove mildew smell from clothes and keep them fresh for good.

This guide will show you how to tackle mildew odors step by step, including natural remedies and tips to prevent future issues.

Why Clothes Smell Like Mildew

Clothes develop a mildew smell when moisture gets trapped in fibers for too long, creating a perfect environment for mold and bacteria. Common causes include:

  • Leaving wet laundry in the washing machine too long
  • Storing clothes in damp closets or drawers
  • Wearing clothes in humid conditions without proper drying
  • Accidental spills or sweat that aren’t washed promptly

Understanding the cause can help prevent the smell from returning.

What You’ll Need

Gather these supplies before you begin so you can treat your clothes efficiently:

  • White vinegar
  • Baking soda
  • Liquid laundry detergent
  • Hydrogen peroxide (for whites only)
  • Washing machine or large basin
  • Soft brush (optional)
  • Dryer or clothesline for air drying

Step-by-Step: How to Remove Mildew Smell from Clothes

Follow these steps for effective odor removal:

  • Pre-soak your clothes
    Fill a basin or washing machine with warm water and add 1–2 cups of white vinegar. Soak your clothes for 30–60 minutes. Vinegar naturally kills mildew bacteria and neutralizes odors.
  • Apply baking soda
    After soaking, sprinkle 1/2 cup of baking soda directly on the damp clothes. Baking soda helps absorb lingering smells. Gently rub it into the fabric if needed.
  • Wash thoroughly
    Run your clothes through a regular wash cycle using your usual liquid laundry detergent. For heavily mildewed garments, consider adding an extra rinse cycle to remove all residue.
  • Treat whites or stubborn odors
    For white clothes or fabrics that can handle it, add 1/2 cup of hydrogen peroxide to the wash. This helps kill bacteria and brighten fabrics.
  • Dry immediately
    Never leave washed clothes sitting wet in the machine. Dry them thoroughly on a clothesline in the sun or in a dryer on a high setting suitable for the fabric. Sunlight also helps kill residual bacteria.
  • Repeat if necessary
    For particularly stubborn odors, repeat the soaking and washing process. Most smells will disappear after one or two treatments.

How to Remove Mildew Smell from White Clothes

White garments can often tolerate stronger treatments. Here’s what to do:

  • Pre-soak in 1 part vinegar to 4 parts water for 30 minutes
  • Add 1/2 cup hydrogen peroxide during the wash
  • Use hot water if the fabric label allows, as heat helps remove odor-causing bacteria

Avoid bleach unless absolutely necessary, as it can react with mildew and sometimes intensify odors.
