The fastest way to remove mold smell

The mold smell in clothes comes from volatile organic compounds (VOCs) that the mold releases as it grows. To remove it, you need to kill the mold spores still on the fabric and then air out the garment long enough for the smell to dissipate. The most effective method is a combination of vinegar wash, sunlight exposure, and time — usually three to seven days total.

Start by washing the clothes in hot water (if the fabric allows it) with one cup of white vinegar added to the rinse cycle, or one-half cup in the wash cycle itself. Vinegar kills mold spores and neutralizes the smell at the source. Do not use fabric softener, which can trap moisture and odor. After washing, hang the clothes outside in direct sunlight for at least two full days. Sunlight is a natural mold killer and helps evaporate remaining moisture and odor compounds.

If the smell persists after sunlight exposure, repeat the vinegar wash and hang the clothes outside again. Some fabrics or heavy smells may need two or three cycles. If you cannot hang clothes outside, use a clothes dryer on medium heat for 45 minutes to an hour, then hang in a well-ventilated room for several days.

Key Takeaways

  • White vinegar in the rinse or wash cycle kills mold spores and neutralizes the smell without damaging most fabrics.
  • Direct sunlight for two or more days is the most effective way to finish removing odor after washing.
  • Do not use fabric softener or dryer sheets, as they trap moisture and can lock in the smell.
  • Clothes that still smell after one cycle may need a second vinegar wash and sunlight exposure.
  • Baking soda, activated charcoal, or crumpled newspaper in a sealed bag can absorb remaining odor if hanging outside is not an option.

When to wash versus when to discard

Not all moldy clothes are worth saving. If the mold has visibly stained the fabric or the smell is extremely strong and the garment is inexpensive, discarding it is often faster and safer than attempting removal. Mold that has penetrated deep into thick fabrics like winter coats or upholstered items is harder to fully remove.

Clothes worth treating are those with light mold smell, no visible staining, and fabrics that can tolerate hot water or vinegar — cotton, linen, and synthetic blends. Delicate fabrics like silk or wool should be treated more carefully: use cool water, lower vinegar concentration (one-quarter cup in a full wash), and skip the dryer. If you are uncertain whether a garment can handle vinegar, test it on a hidden seam first.

Clothes that have been damp for more than a few days and smell strongly of mold have likely developed deep mold colonies. These are riskier to wash because they can release spores into your washing machine, potentially contaminating other loads. If you choose to wash them, run a separate load and clean the machine afterward with a vinegar cycle.

Using baking soda and other odor absorbers

Baking soda is a secondary tool, not a primary one — it absorbs odor but does not kill mold spores. Use it after washing and drying. Sprinkle baking soda directly onto the fabric, place the garment in a sealed plastic bag or container, and leave it for 24 to 48 hours. The baking soda will absorb remaining odor molecules. Shake out the powder thoroughly before wearing.

Activated charcoal works similarly and is especially useful for clothes you cannot wash, such as dry-clean-only items. Place crumpled activated charcoal (available at hardware stores or online) in a sealed bag with the garment for 48 hours. Activated charcoal absorbs odor more effectively than baking soda but costs more.

Crumpled newspaper is a free alternative that works reasonably well for light smells. Place the garment in a sealed bag with loosely crumpled newspaper and leave it for 24 to 48 hours. Change the newspaper halfway through if possible. This method is slower than baking soda but requires no purchase.

None of these methods replace washing — they only mask or absorb remaining odor after the mold spores have been killed. Use them as a final step if the smell lingers after vinegar washing and sunlight exposure.

Preventing mold smell from returning

Mold returns when clothes are stored in damp, poorly ventilated spaces. After treating moldy clothes, store them in a closet or drawer with good air circulation, away from exterior walls or bathrooms where humidity collects. Use wooden hangers rather than plastic, which can trap moisture against the fabric.

If your home has high humidity (above 60 percent), consider a dehumidifier in the bedroom or closet. Mold thrives in humidity above 50 percent, so keeping the air dry is the most effective prevention. Open closet doors periodically to allow air to move through, and avoid storing clothes in sealed plastic bins or bags for long periods.

Wash and fully dry clothes before storing them. Even a small amount of residual moisture can allow mold to grow over weeks or months. If you live in a very humid climate or have experienced mold before, inspect stored clothes every few months and air them out in sunlight if you notice any dampness or smell.

Treating clothes that cannot be washed

Dry-clean-only items, leather jackets, and wool coats require different handling. Do not attempt to wash these in water, as it will damage them. Instead, hang them outside in direct sunlight for three to five days. Sunlight alone will kill most mold spores and reduce odor significantly, though it may not eliminate the smell completely.

After sunlight exposure, place the garment in a sealed bag with activated charcoal or crumpled newspaper for 48 hours to absorb remaining odor. If the smell persists, take the item to a professional dry cleaner and tell them it has mold smell — they have industrial equipment and solvents that can remove odor that home methods cannot.

For leather items, wipe the surface with a cloth dampened in white vinegar (not soaked), then hang in sunlight. Leather is naturally resistant to mold, so surface treatment is usually enough. Avoid getting leather too wet, as excess moisture can damage the material.

When to call a professional

If the mold smell is extremely strong, affects many garments, or returns repeatedly despite your efforts, the problem may be in your home rather than the clothes. Mold growing in your closet, walls, or HVAC system will contaminate clean clothes as soon as you store them. In this case, treating individual garments will not solve the problem.

Contact a mold inspector or remediation company if you notice mold smell in multiple rooms, see visible mold growth, or have a history of water damage or flooding. These professionals can identify the source and recommend repairs. Until the source is fixed, even freshly cleaned clothes will absorb mold smell from the air.

For garments with heavy mold growth, visible staining, or extreme odor, a professional dry cleaner with ozone treatment or other industrial odor removal may be your best option. This costs more than home treatment but works faster and more thoroughly for severely affected items.

Frequently Asked Questions

Can I use bleach to remove mold smell from clothes?

Bleach kills mold spores but damages most fabrics and can cause discoloration. White vinegar is safer and nearly as effective. Use bleach only on white cotton items you do not mind potentially damaging, and dilute it to one part bleach to ten parts water. For colored or delicate fabrics, stick with vinegar.

How long does it take for mold smell to go away?

With vinegar washing and two to three days of sunlight exposure, most mold smell will be gone within a week. Heavy smells or clothes that were damp for a long time may take two to three weeks of repeated treatment. Some very old or deeply penetrated smells may never fully disappear.

Will the smell come back after I wash the clothes?

The smell will not return if the clothes are stored in a dry, well-ventilated space. If your home is damp or has poor air circulation, mold can grow again within weeks or months. Use a dehumidifier and may support closets have air flow to prevent regrowth.

Can I wash moldy clothes with my other laundry?

Avoid washing heavily moldy clothes with other garments, as mold spores can spread to clean items. Wash them separately, and run a vinegar cycle through your machine afterward to clean it. Light mold smell on clothes is usually safe to wash with other loads.

What if the clothes still smell after vinegar and sunlight?

Repeat the vinegar wash and sunlight cycle one or two more times. If the smell persists after three attempts, use baking soda or activated charcoal in a sealed bag for 48 hours. If it still does not work, the mold may be too deep to remove at home, and professional dry cleaning is your next option.
