Quick Answer
The best way to remove mildew smell from clothes is to wash them with white vinegar or baking soda, which neutralize odor‑causing mold and bacteria. Start by running a hot rinse cycle with 1 cup of vinegar, then wash normally with detergent. This method works even on clothes that have sat damp for too long.
What You’ll Need
- White vinegar
- Baking soda
- Laundry detergent
- Hot water
- Washing machine
Step-by-Step Instructions
1. Run a Hot Rinse Cycle With Vinegar
Add 1 cup of white vinegar directly into the drum and run a hot rinse cycle. Vinegar breaks down mold spores and neutralizes deep odors.
2. Wash With Detergent + Baking Soda
Add your regular detergent, then sprinkle ½ cup of baking soda into the drum. This boosts deodorizing power and removes lingering mustiness.
3. Use the Longest Wash Cycle
A longer cycle gives the cleaning agents more time to break down mildew compounds.
4. Rewash if the Smell Persists
For severe odors, repeat the vinegar rinse followed by a detergent wash.
5. Dry Clothes Completely
Dry on high heat if the fabric allows. Moisture is what causes mildew, so complete drying is essential.
Why This Works
Mildew odors come from microbial growth—usually mold spores that thrive in damp fabric. Vinegar contains acetic acid, which breaks down the cell structure of mold and eliminates the compounds responsible for the musty smell. Baking soda neutralizes acidic and alkaline odor molecules, making it a powerful secondary deodorizer. Combined, they remove both the source of the odor and the odor itself.
Common Mistakes to Avoid
- Using fabric softener — it traps odors instead of removing them.
- Air‑drying musty clothes — heat is needed to kill remaining spores.
- Using too much detergent — residue can worsen odors.
- Skipping the vinegar rinse — detergent alone rarely removes mildew.
When to Try Something Else
If vinegar and baking soda don’t fully eliminate the smell, try an oxygen‑based cleaner or a mildew‑specific laundry additive. These products penetrate deeper into fibers and work well for towels, gym clothes, and items that have been left damp for days.
Related Questions
Why do my clothes smell musty even after washing?
This usually happens when detergent residue traps moisture, creating a breeding ground for mildew. Using too much detergent or washing in cold water can make the problem worse.
Can mildew smell be harmful?
While the odor itself isn’t dangerous, the mold spores causing it can irritate sensitive skin or allergies. Removing the smell also removes the underlying microbial growth.
Does vinegar damage clothes?
No — white vinegar is safe for most fabrics and helps dissolve buildup. Avoid using it on delicate silks or specialty fabrics.
Conclusion
Removing mildew smell from clothes is simple once you use the right combination of vinegar, baking soda, and heat. These methods eliminate odors at the source and keep your laundry fresh.
