Wash moldy clothes in hot water with detergent and vinegar
The fastest way to remove mold from clothes is a hot-water wash with regular laundry detergent plus white vinegar. Vinegar kills mold spores on contact. Use one cup of white vinegar in the rinse cycle, or add it directly to the wash with your detergent. Hot water matters—aim for the hottest setting the fabric can handle without damage. Check the garment's care label first.
If the mold covers a large area or the fabric is delicate, soak the item in vinegar solution before washing. Mix one part white vinegar with three parts water, submerge the moldy section, and let it sit for one hour. Then wash normally. This pre-treatment breaks down the mold before agitation in the machine, which reduces the chance of spreading spores to other clothes.
Dry the clothes in direct sunlight if possible. Sunlight naturally kills remaining mold spores and helps prevent regrowth. If you must use a dryer, use the highest heat setting the fabric allows. Never store damp or damp-feeling clothes—mold will return within 24 to 48 hours.
Key Takeaways
- White vinegar kills mold spores in the wash; use one cup in the rinse cycle or soak the garment for one hour before washing.
- Hot water is essential—check the care label and use the highest temperature safe for the fabric.
- Sunlight is the most effective drying method because it kills remaining spores and prevents mold from returning.
- Store clothes only when completely dry; mold will regrow in damp fabric within one to two days.
- If mold has penetrated deep into thick fabrics like winter coats, professional dry cleaning may be more effective than home washing.
When to use bleach instead of vinegar
Bleach kills mold faster than vinegar, but it damages or discolors most fabrics. Use bleach only on white cotton, white linen, or other white natural fibers that can tolerate it. Never use bleach on colored clothes, synthetics, or delicate fabrics—it will leave permanent marks.
If you decide to use bleach, dilute it first. Mix one part bleach with ten parts water, soak the moldy area for 10 minutes, then wash the garment normally in hot water. Rinse thoroughly twice to remove all bleach residue, which can weaken fabric fibers over time. Dry in sunlight.
For most people, vinegar is the safer choice because it works on all fabric types and colors. Bleach is worth considering only if the item is white and the mold is severe.
How to treat mold on leather, suede, and specialty fabrics
Leather and suede cannot go in the washing machine. Instead, wipe the moldy surface with a cloth dampened in white vinegar. Use a separate cloth to dry the item when ready afterward. If the mold is stubborn, let the vinegar sit for 15 to 20 minutes before wiping. Repeat if needed.
For suede, be gentler—vinegar can darken the nap. Test on a hidden area first. If vinegar leaves a mark, try rubbing alcohol instead. Dampen a cloth with rubbing alcohol, wipe the moldy spot, and dry when ready with a clean cloth.
Wool coats, cashmere, and other delicate knits should be dry-cleaned if mold is visible. Home treatment risks spreading spores deeper into the fibers or damaging the fabric. A professional cleaner has stronger antifungal treatments and can handle the garment without harm.
Why mold grows on stored clothes and how to stop it
Mold grows on clothes in storage because of three conditions: moisture, darkness, and poor air circulation. Closets, plastic bins, and sealed bags create all three. Even clothes that feel dry to the touch can hold enough moisture for mold to start growing within days.
To prevent mold in storage, keep clothes completely dry before putting them away—use a dehumidifier in your closet if humidity stays above 50 percent. Store items in breathable cotton garment bags or open shelving rather than plastic bins or sealed containers. Leave space between hangers so air can flow around each item. In damp climates, place open boxes of baking soda or activated charcoal in the closet to absorb moisture.
Cedar blocks and mothballs also discourage mold, though they work primarily against insects. They do not replace proper ventilation and dryness. If your closet smells musty or feels damp, the real problem is humidity, not the storage method—address the moisture first.
Washing clothes that were stored with mold
If clothes were stored near moldy items but do not show visible mold, wash them anyway. Mold spores are invisible and can settle on fabric without visible growth yet. Use the same hot-water wash with vinegar described above, even if you see no spots. This removes spores before they have a chance to grow.
If the storage area had a strong musty smell, the clothes absorbed mold odor even if no visible growth appeared. Vinegar in the wash will remove the smell. If the smell persists after one wash, repeat the vinegar wash. Sunlight drying also helps eliminate odor.
Do not return clothes to the same storage space until you have fixed the moisture problem. Otherwise, mold will return to the clothes within weeks.
When to throw clothes away instead of washing them
Some mold damage is too severe to reverse. If mold has been growing on a garment for weeks or months, the spores may have penetrated so deep into the fibers that washing cannot reach them. The item will smell musty even after treatment, and mold will return quickly.
Thick, tightly woven fabrics like winter coats, quilted jackets, and heavy sweaters are harder to clean than thin cotton. If mold covers more than 25 percent of the garment or has created visible staining that does not wash out, the cost of professional dry cleaning may exceed the item's value.
If you are uncertain whether an item is worth saving, try the vinegar wash first—it costs almost nothing. If the smell returns within a week or the staining remains, the garment is not worth keeping. Mold that returns that quickly means the spores are too deep to remove.
What to do if mold is growing inside your washing machine
If clothes smell musty after washing, the mold may be growing inside the machine itself, not on the clothes. Front-load washers are especially prone to mold because water sits in the rubber gasket and drum after each cycle.
Run an empty hot-water cycle with two cups of white vinegar to clean the machine. Pour the vinegar directly into the drum, not the detergent dispenser. Let it run through a full cycle. Repeat if the smell persists. After each wash, leave the door open to let the drum dry completely.
If the smell does not go away after two vinegar cycles, the mold may be in the drain hose or pump—this requires professional service. Do not continue washing clothes in a moldy machine; the mold will transfer to every load.
Frequently Asked Questions
Can I use a dryer instead of hanging clothes in the sun?
Yes, but sunlight is more effective. A dryer on high heat kills most mold spores, but some may survive. Sunlight kills spores and also removes musty odors that heat alone cannot. If you must use a dryer, run it on the highest heat the fabric allows, then hang the item in sunlight for a few hours if possible.
Will mold come back if I wash clothes but don't fix the humidity in my closet?
Yes. Washing removes the current mold, but if your closet stays damp, mold will grow back on the same clothes within weeks or months. You must address the moisture problem—use a dehumidifier, improve ventilation, or switch to breathable storage—or the mold will return repeatedly.
Is it safe to wear clothes that had mold but are now clean?
Yes, once the clothes are washed and dried properly, they are safe to wear. Mold spores are killed by hot water, vinegar, and sunlight. The garment is no different from any other clean item. If you are concerned about lingering spores, run a second wash cycle.
Can I use baking soda instead of vinegar to remove mold?
Baking soda absorbs odors but does not kill mold spores the way vinegar does. You can use baking soda as a pre-soak to reduce smell—sprinkle it on the damp garment and let it sit for a few hours—but follow up with a vinegar wash to actually remove the mold.
How long does it take for mold to grow on damp clothes in a hamper?
Mold can begin growing within 24 to 48 hours on damp fabric at room temperature. In warm, humid climates, growth can start even faster. Never leave wet or damp clothes in a hamper or washing machine. Wash them when ready or hang them to dry first.
