Wash moldy clothes separately in hot water with vinegar or bleach
The fastest way to remove mold from fabric is a hot-water wash with either white vinegar or chlorine bleach, depending on the fabric type. Vinegar works on most materials and kills mold spores without the harshness of bleach. Bleach is stronger but will fade or damage colored fabrics, so use it only on white cotton or linens.
Wash moldy items alone—never with clean clothes—because mold spores spread easily in the wash cycle. Use the hottest water the fabric can handle (check the care tag), add one cup of white vinegar to the rinse cycle or half a cup of bleach to the wash water, and run a full cycle. The combination of heat, agitation, and the antifungal agent kills active mold and prevents regrowth for several weeks.
After washing, dry the clothes completely in direct sunlight if possible. Sunlight is a natural mold killer and helps prevent the spores from settling back into the fabric. If you must use a dryer, run it on high heat for at least 45 minutes. Never hang damp clothes in a dark or poorly ventilated space, because that is exactly where mold thrives.
Key Takeaways
- Wash moldy clothes separately in the hottest water safe for the fabric, using either white vinegar (one cup in the rinse) or bleach (half cup in the wash water for whites only).
- Dry clothes in direct sunlight or a hot dryer for at least 45 minutes—never hang them damp in a dark or humid space.
- Clothes with heavy mold growth or a musty smell that does not fade after one wash may need a second treatment or may be too damaged to save.
- Store clean clothes in a dry closet with air circulation, and use moisture absorbers like silica gel or baking soda in sealed storage containers.
- If mold returns quickly after washing, the storage space itself has a moisture problem that must be fixed or clothes will mold again.
Treat stubborn mold stains with a soak before washing
If clothes have visible dark or green spots after one wash, soak them before running a second cycle. Mix one part white vinegar with three parts water in a basin or bucket, submerge the clothes, and let them sit for at least two hours—overnight is better. The vinegar penetrates the fibers and loosens mold that surface washing missed.
For white fabrics, you can use a bleach soak instead: mix one part bleach with ten parts water, soak for one to two hours, then rinse thoroughly before washing. Do not leave clothes in bleach longer than two hours, because it weakens fibers and can cause yellowing. After soaking, wash the clothes again in hot water with vinegar or bleach as described above.
If mold stains remain after a second wash and soak, the mold has penetrated too deep into the fibers to remove safely. At that point, the fabric is likely damaged enough that washing again will not help, and you should consider whether the item is worth keeping.
Handle the smell: vinegar rinses and sun-drying work best
Mold smell (that musty, earthy odor) often lingers even after mold is visually gone. This happens because mold spores release compounds called volatile organic compounds that create the smell, and they can persist in fabric fibers. A vinegar rinse after washing removes much of this odor naturally.
Run a second rinse cycle with one cup of white vinegar and no detergent. The vinegar neutralizes the smell-causing compounds and evaporates as it dries. If the smell is still strong after this rinse, hang the clothes in direct sunlight for several hours or overnight. UV light breaks down the remaining odor compounds and kills any surviving spores.
Do not mask the smell with fabric softener or perfume before the smell is actually gone—those products trap moisture and can make mold return faster. If the musty smell does not fade after a vinegar rinse and sun-drying, the mold damage is severe and the clothes should not be worn or stored with other items.
Prevent mold from returning by controlling moisture in storage
Mold grows only when fabric stays damp or in a humid environment for more than 24 to 48 hours. Once clothes are completely dry, the risk drops sharply—but it returns if they are stored in a damp closet or sealed container without air circulation.
Store clean, dry clothes in a closet with a door that opens regularly (not a sealed plastic bin), and keep the closet temperature between 60 and 75 degrees Fahrenheit with humidity below 50 percent. If your home is naturally humid or you live in a damp climate, use a small dehumidifier in the closet or place moisture absorbers like silica gel packets, activated charcoal, or open boxes of baking soda on shelves. Replace baking soda every three months.
For long-term storage of seasonal clothes, use breathable cotton storage bags instead of plastic, and include moisture absorbers inside. Check stored items every few weeks, especially in spring and fall when humidity fluctuates. If you notice a musty smell developing, remove the items, air them in sunlight, and improve ventilation in the storage space before putting them back.
Know when clothes are too damaged to save
Some mold damage is permanent. If clothes have been damp and moldy for more than a few weeks, the mold may have weakened the fibers so much that washing damages them further. Signs of severe damage include holes, tears, or areas where the fabric crumbles when you touch it.
If the smell does not fade after two washes with vinegar and a full day of sun-drying, the mold has likely penetrated the fibers at a level that cannot be reversed. Wearing or storing these clothes risks spreading mold spores to other items and to your home's air. In these cases, it is safer to discard the item than to keep trying to save it.
Before discarding moldy clothes, place them in a sealed plastic bag to prevent spores from spreading to your trash or other areas of your home. Tie the bag tightly and put it directly in an outdoor trash bin if possible.
Use the right water temperature and cycle for different fabrics
Hot water kills mold spores more effectively than warm or cold water, but not all fabrics can handle high heat. Check the care tag on each item before washing. Cotton, linen, and white fabrics tolerate 130°F (54°C) or hotter. Synthetics like polyester, nylon, and acrylic usually max out at 104°F (40°C), and delicate fabrics like silk or wool should not exceed 86°F (30°C).
If a delicate fabric is moldy, use the warmest water the tag allows, add vinegar instead of bleach, and run a gentle or hand-wash cycle. Delicate fabrics are more prone to mold because they are often stored in tight spaces with poor air flow. After washing, dry them flat in sunlight rather than hanging, because hanging can stretch the fibers while they are damp.
For heavily soiled or work clothes made of sturdy cotton or canvas, use the hottest water available and a heavy-duty or normal cycle. These fabrics can handle aggressive washing and benefit from the extra agitation that helps dislodge mold spores.
Frequently Asked Questions
Can I use OxiClean or other oxygen-based cleaners on moldy clothes?
Oxygen-based cleaners like OxiClean can help remove mold stains and odor, but they work best as a supplement to vinegar or bleach, not as a replacement. Add one scoop of OxiClean to the wash water along with vinegar for extra stain-lifting power on colored fabrics. However, OxiClean alone does not kill mold spores as reliably as heat and vinegar or bleach do.
Is it safe to dry moldy clothes in an indoor dryer?
Yes, if the clothes are washed first and the dryer is run on high heat for at least 45 minutes. The heat kills remaining mold spores. However, if you dry unwashed moldy clothes in a dryer, you risk spreading spores inside the machine and throughout your home. Always wash before drying, and run the dryer on the highest heat setting the fabric allows.
What if my clothes smell musty but I do not see visible mold?
Musty smell means mold spores are present even if you cannot see them. Wash the clothes in hot water with vinegar, then dry them in direct sunlight for several hours. If the smell returns within a few days, the storage space has a moisture problem—improve ventilation or use a dehumidifier before storing the clothes again.
Can I wash moldy clothes with regular detergent and skip the vinegar or bleach?
Regular detergent cleans dirt but does not kill mold spores effectively. You need the antifungal action of vinegar or bleach plus hot water to stop mold from returning. Detergent alone may remove the visible mold but leave spores behind, which will grow back within days.
How long does it take for mold to grow back on clean clothes?
If clothes are stored in a dry space with good air circulation, mold will not return. If they are stored in a damp closet or sealed container, mold can begin growing again within two to four weeks, depending on humidity levels. This is why controlling moisture in your storage space is more important than any washing technique.
