Wash moldy clothes in hot water with detergent and bleach or vinegar
The fastest way to remove mold from most fabrics is a hot-water wash with your regular detergent plus either chlorine bleach or white vinegar. Hot water kills the mold spores; the detergent lifts them away; the bleach or vinegar prevents regrowth. For white cotton, linen, or synthetic fabrics that can tolerate bleach, add one cup of bleach to a full load. For colored fabrics or delicates, use one to two cups of white vinegar instead—it works nearly as well and won't fade dyes.
Wash the moldy clothes separately from other laundry the first time, so spores don't spread. Use the hottest water the fabric label allows. If the label says cold water only, that fabric may need a different approach—see the section below on delicate items.
After washing, dry the clothes completely in direct sunlight if possible. Sunlight is a natural mold killer and helps prevent the smell from returning. If you must use a dryer, use the hottest setting the fabric can handle. Do not store damp or drying clothes in a closed space.
Key Takeaways
- Hot water, detergent, and either bleach or vinegar will remove mold from most washable fabrics in a single cycle.
- For delicate fabrics that cannot tolerate heat or bleach, soak in vinegar solution for several hours before washing in cool water.
- Sunlight is the most effective drying method because UV rays kill remaining mold spores and prevent the musty smell from returning.
- Mold returns when clothes are stored in damp, poorly ventilated spaces, so keep closets and drawers dry and allow air to circulate.
- If mold has penetrated deep into thick fabrics like wool coats or leather, professional dry cleaning may be necessary.
How to treat delicate fabrics that cannot handle hot water or bleach
Wool, silk, linen blends, and other delicate fabrics often carry a "cold water" or "hand wash" label, which means hot water and bleach will damage them. For these items, soak the moldy garment in a solution of one part white vinegar to three parts cool water for two to four hours. The vinegar will kill the mold without weakening the fibers.
After soaking, rinse the garment thoroughly in cool water and wash it by hand or on a gentle cycle with mild detergent. Do not wring or twist—instead, gently squeeze out water. Lay the item flat to dry in sunlight if possible, or hang it in a well-ventilated area away from direct heat. Never put delicate moldy fabrics in a dryer, as the heat can set any remaining mold spores into the fibers.
Treating mold on leather, suede, and non-washable materials
Leather jackets, suede shoes, and other non-washable items cannot go in the washing machine. For these, wipe the surface with a cloth dampened in white vinegar or a 50-50 solution of vinegar and water. Work in a well-ventilated area or outdoors, because the smell can be strong. Wipe gently to avoid pushing mold spores deeper into the material.
After wiping, place the item in direct sunlight for several hours. Sunlight will kill remaining spores and help dry the material. If the mold smell persists after drying, place the item in a sealed bag with crumpled newspaper, activated charcoal, or baking soda for 24 to 48 hours. These materials absorb odor. If the mold has visibly stained the leather or suede or if the smell does not fade, take the item to a professional dry cleaner—they have industrial-strength treatments that home methods cannot match.
Why mold grows on stored clothing and how to prevent it
Mold grows on clothes when they are stored in damp, poorly ventilated spaces—typically closets, basements, or sealed plastic bins. Mold spores are always present in the air, but they only germinate when moisture and warmth combine. A closet with high humidity or a basement that floods seasonally creates the exact conditions mold needs.
To prevent mold, keep your storage spaces dry. Use a dehumidifier in basements or damp closets, or leave the closet door open to allow air to circulate. Never store clothes in sealed plastic bins; use breathable fabric storage boxes or open shelving instead. Before storing seasonal clothes, make sure they are completely dry and clean. Even a small amount of moisture trapped in a sealed container will encourage mold growth over weeks or months.
If you live in a humid climate or have had mold problems before, place open boxes of baking soda or activated charcoal in your closet or storage area. These absorb moisture and odor. Replace them every two to three months. In basements, keep clothes on shelves or racks at least six inches off the floor, so water from minor flooding does not reach them when ready.
When to throw away moldy clothes instead of trying to save them
Some mold damage is too deep to reverse at home. If mold has been growing on a garment for weeks or months, the spores may have penetrated the fibers so thoroughly that washing will not remove them completely. Thick fabrics like wool coats, down jackets, or quilted items are especially vulnerable because mold can grow inside the padding where water and detergent cannot easily reach.
If a garment still smells musty after washing and drying in sunlight, or if you can see mold stains that did not come out, the item is likely not worth saving. Mold that returns after treatment is a sign the spores have established themselves deep in the fabric. In these cases, discarding the item prevents the mold from spreading to nearby clothes and saves you the cost and effort of repeated treatments.
Dealing with mold smell that lingers after washing
Sometimes clothes wash clean but still smell musty. This happens when mold spores have died but their odor compounds remain in the fabric. To remove the smell, wash the clothes again using the same hot-water method, but add one-half cup of baking soda to the wash cycle along with your detergent and bleach or vinegar. Baking soda neutralizes odor rather than just masking it.
Alternatively, soak the clothes in a solution of one cup of white vinegar per gallon of water for 30 minutes before washing normally. Vinegar breaks down the odor compounds. After washing, dry the clothes in direct sunlight—UV rays also help eliminate lingering smell. If the odor persists after a second wash, the mold may have penetrated too deeply, and professional dry cleaning is the next step.
Frequently Asked Questions
Can I use bleach on colored clothes to remove mold?
Bleach will remove the mold but will also fade or discolor most dyed fabrics. Use white vinegar instead—it kills mold spores just as effectively and is safe for colors. If the garment is white or you do not mind lightening it, bleach is fine and works slightly faster.
Is mold on clothes dangerous to breathe?
Mold spores can irritate the lungs and sinuses, especially in people with asthma or mold allergies. Wash moldy clothes in a well-ventilated area and avoid inhaling directly from the garment. If you have a mold allergy or respiratory condition, consider having a professional dry cleaner handle heavily molded items instead.
How long does it take for mold to grow on damp clothes?
Mold can begin growing on damp fabric within 24 to 48 hours, depending on temperature and humidity. In warm, humid conditions, visible mold can appear in as little as one week. This is why it is important to dry clothes completely before storing them and to keep storage areas well-ventilated.
Can I use a washing machine to clean clothes that had mold, or will it spread mold to the machine?
Your washing machine will not be harmed by washing moldy clothes. Run an empty hot-water cycle with one cup of bleach after washing the moldy items if you are concerned, but it is not necessary—the detergent and heat kill mold spores. The machine itself does not become moldy from one load of contaminated clothes.
What if mold comes back after I wash and dry the clothes?
Mold returns when clothes are stored in damp conditions again. Make sure the garment is completely dry before storing it, and keep your closet or storage area dry and ventilated. If mold keeps returning to the same item, the spores may have penetrated too deeply to remove at home—consider discarding the item or taking it to a professional cleaner.
