There’s nothing more frustrating than pulling freshly washed clothes from the machine only to be hit with that unmistakable musty smell. Even after a full wash cycle, mildewed clothes can retain a lingering odor that makes your entire laundry feel dirty. If you’ve been wondering how to eliminate mildew smell from clothes once and for all, you’re not alone, and the good news is, there are proven ways to solve the problem.
This guide breaks down everything you need to know, from understanding what causes mildew to form in the first place to the best way to get rid of mildew smell in clothes using natural and commercial solutions. You’ll also learn how to prevent the odor from returning, how to maintain a clean washer, and which laundry detergent for mildew works best. Let’s dive in and help you reclaim the fresh scent your clothes deserve.
What Causes Clothes to Smell Like Mildew?
Understanding the root causes of that stubborn mildew smell is the first step to keeping your laundry fresh and odor-free.
1. Humidity and moisture
High humidity levels in your laundry area or inside the washer can create the ideal setting for mildew growth. Clothes that sit damp for too long, either in the washer or laundry basket, are especially vulnerable. The excess moisture becomes a breeding ground for mildew spores, which embed in the fabric and lead to stubborn odors.
2. Lack of airflow
A poorly ventilated space traps moisture, increasing the likelihood of mildew formation. When you dry your clothes indoors without proper airflow or leave them in a closed washing machine, it doesn’t allow for proper evaporation. As a result, removing mildew smell becomes harder because the spores have had time to settle and grow.
3. Dirty washer
Sometimes, the problem isn’t the clothes, it’s the washer. A buildup of detergent, fabric softener, and grime in your washing machine can trap moisture and harbor mildew. Each time you wash a load, these spores can transfer to your clothing, undoing any cleaning progress. Regular cleaning is key to preventing this transfer and ensuring your washer isn’t the source of your problem.
How to Identify Mildew Vs Mold on Clothes?
Mildew typically appears as a gray or white powdery substance, often paired with a musty smell. Mold, on the other hand, may look darker black or green, and can be slimier or more textured. While both are fungi, mold tends to be more destructive and harder to remove. If you notice stains along with an unpleasant odor, you’re likely dealing with mold rather than just mildew. Understanding the difference helps you choose the right approach for treatment and prevention.

How to Rid Clothes of Mildew Smell
If you’re looking for the best way to get rid of mould smell in clothes, a multi-step approach is most effective.
Here’s how to remove the smell of mildew from clothes and keep your laundry smelling fresh:
Rewash with Hot Water
If the fabric allows, use hot water to kill mildew spores. Cold water might not be effective in removing the odor completely.
Use Vinegar or Baking Soda
Add 1 cup of white vinegar or 1/2 cup of baking soda to your wash cycle. These natural deodorizers break down odor-causing bacteria.
Choose the Right Detergent
Look for a specialized laundry detergent for mildew. These are formulated to combat and neutralize mildew odors.
Double Rinse
After washing, run an extra rinse cycle to ensure all residues are completely removed.
Dry Thoroughly
Sun-drying is a natural mold killer thanks to UV rays. If that’s not possible, use a dryer on high heat.
Repeat if Necessary
For persistent smells, you may need to repeat the process. Stubborn mildew can require more than one treatment.
How Can I Prevent Mildew Smell from Returning?
Prevention starts with small but consistent habits:
- Remove Clothes Immediately: Don’t let wet laundry sit in the washer. Mold and mildew can start to form in just a few hours.
- Dry Completely: Ensure clothes are fully dry before folding or storing them.
- Store in a Dry Place: Avoid storing clothes in damp basements or closets with poor ventilation.
- Use Moisture Absorbers: In humid climates, consider using silica packets or dehumidifiers in closets or drawers.
Should I Be Concerned About Health Risks from Mildewed Clothes?
Yes, mildew can pose health risks, especially for those with allergies, asthma, or respiratory sensitivities. Inhaling mildew spores or having skin contact with mildewed fabrics can lead to irritation, coughing, or rashes. That’s why removing mildew smell from clothes isn’t just about comfort; it’s also about protecting your well-being.

How to Keep Your Washer Fresh to Help Prevent Mildew Odors
Your washer needs regular care to keep clothes smelling fresh.
Here are a few tips:
- Run a Cleaning Cycle: At least once a month, run a hot water cycle with vinegar or a washer cleaning tablet.
- Leave the Door Open: After every wash, leave the door slightly ajar to allow airflow and prevent moisture buildup.
- Wipe the Seals and Dispenser Drawers: Mildew can hide in rubber seals and detergent compartments. Don’t overlook these areas.
