Wash moldy clothes in hot water with vinegar or bleach
The fastest way to remove mold from clothes is to wash them in the hottest water the fabric can handle, adding either white vinegar or bleach to kill the mold spores. For most cotton and synthetic fabrics, use one cup of white vinegar in the wash cycle, or one cup of bleach if the garment is white or colorfast. Hot water matters because mold thrives in cool, damp conditions—heat disrupts the spores and prevents regrowth.
Before washing, brush off any visible mold outside in direct sunlight or over a trash can. Do this outdoors to avoid spreading spores inside your home. If the mold is heavy or the smell is strong, soak the clothes in vinegar solution (one part vinegar to three parts water) for one to two hours before washing. This loosens the mold and reduces the odor that often lingers even after washing.
Dry the clothes in direct sunlight if possible—sunlight naturally kills mold spores and removes musty smells better than any dryer setting. If you must use a machine dryer, run it on high heat for at least 45 minutes. Never store damp or partially dry clothes, as this creates the exact conditions mold needs to return.
Key Takeaways
- Brush off visible mold outdoors before washing to prevent spreading spores inside your home.
- Wash moldy clothes in the hottest water safe for the fabric with one cup of white vinegar or bleach added to the cycle.
- Soak heavily molded clothes in vinegar solution for one to two hours before washing to loosen mold and reduce odor.
- Dry clothes in direct sunlight or on high heat in a machine dryer for at least 45 minutes to kill remaining spores.
- Store clean, completely dry clothes in a cool, dry place with good air circulation to prevent mold from returning.
When to soak clothes before washing
Soaking works best when mold has been growing for more than a few days or covers a large area of the garment. If you can see mold spots or smell a strong musty odor, soak the item before the regular wash. Mix one part white vinegar with three parts water in a bucket or sink, submerge the clothes, and let them sit for one to two hours. For delicate fabrics like silk or wool, use a weaker solution—one part vinegar to five parts water—and soak for only 30 minutes.
After soaking, do not rinse the clothes before washing. Transfer them directly to the washing machine and run a normal hot-water cycle with detergent. The vinegar remaining on the fabric will continue working during the wash and will rinse out completely. If the smell persists after one wash, repeat the soak-and-wash process a second time rather than using stronger chemicals on delicate items.
Choosing between vinegar and bleach
White vinegar is safer for colored fabrics and delicate materials because it does not fade or damage fibers the way bleach can. Vinegar is also less harsh on your skin and respiratory system if you have sensitivities. Use vinegar on anything you are unsure about—it works on nearly all fabrics and is gentler overall.
Bleach kills mold faster and more completely, making it the better choice for white cotton clothes, towels, and linens where color loss is not a concern. Bleach also removes the musty smell more effectively in a single wash. Never mix bleach with vinegar or ammonia-based cleaners, as this creates toxic fumes. If you choose bleach, use one cup per load and follow the manufacturer's instructions on your washing machine.
For wool, silk, or synthetic blends, stick with vinegar. These fabrics can be damaged by bleach and may shrink or lose their shape. Test any cleaning solution on a hidden seam or corner first if you are uncertain how the fabric will react.
Handling stubborn mold stains and odors
Sometimes mold leaves behind a stain or smell even after washing. For stains, make a paste of baking soda and water, explore it directly to the spot, and let it sit for 30 minutes before washing again. Baking soda is mild enough for all fabrics and works well alongside vinegar or bleach in the wash cycle.
Musty odors that linger after washing usually mean spores are still present or the clothes dried too slowly. Rewash the item using the soak method, then dry it completely in direct sunlight for at least four hours. If the smell returns after storage, the clothes may have been stored in a damp location again. Always store in a dry closet or drawer with good air flow, and consider placing an open box of baking soda nearby to absorb moisture.
If a garment has been moldy for weeks or the mold has penetrated deep into thick fabrics like winter coats or comforters, one wash may not be enough. Plan on two or three wash cycles spaced a few days apart, with complete sun-drying between each wash. This takes longer but gives you the best chance of fully removing the mold.
Preventing mold from returning to clean clothes
Mold grows in damp, dark, poorly ventilated spaces. After washing and drying, store clothes in a closet or drawer with a small opening or ventilation holes to allow air circulation. Avoid plastic storage bins for long-term storage—use breathable fabric bags or cardboard boxes instead. If you live in a humid climate, place a moisture absorber like silica gel packets or an open box of baking soda in the storage area.
Wash and dry clothes completely before storing them. Even slightly damp fabric will develop mold within days. If you notice a musty smell in your closet, wipe down the walls and shelves with a cloth dampened in vinegar solution, then leave the closet door open for a few hours to air out. Check stored clothes every few weeks, especially in summer or in humid rooms.
If mold keeps returning to the same clothes despite proper storage, the problem may be moisture in the room itself. Look for signs of a leak, condensation on windows, or poor ventilation. Fixing the underlying moisture problem is the only way to stop mold from coming back.
What to do if clothes are beyond saving
If mold has been growing for months, covers more than half the garment, or has created holes or permanent discoloration, the clothes may not be worth saving. Heavily molded items can also harbor mold spores that spread to other clothes during washing. If you decide to discard the item, seal it in a plastic bag before throwing it away so spores do not spread in your trash or to a landfill.
Before discarding, consider whether the mold damage is truly permanent. Mold stains sometimes fade after multiple washes and sun-drying, even if they do not disappear completely. If the garment is valuable or sentimental, try the full soak-and-wash process at least twice before giving up. For everyday clothes, the cost and effort of repeated washing may not be worth it.
Frequently Asked Questions
Can I wash moldy clothes with other clothes?
No. Wash moldy clothes separately in their own load to prevent spreading mold spores to other garments. After the moldy load finishes, run an empty hot-water cycle with vinegar or bleach to clean the washing machine before washing other clothes.
Will a regular dryer kill mold spores?
Yes, if you run it on high heat for at least 45 minutes. However, sunlight is more effective because it kills spores and removes odors that heat alone cannot. Use the dryer as a backup if sunlight is not available, but always aim for sun-drying first.
How long does it take for mold to grow back on clean clothes?
Mold can return within days if clothes are stored in a damp environment. In humid conditions, mold may appear within three to seven days. In dry conditions with good air circulation, clean clothes can stay mold-free for months. The key is keeping storage areas dry and ventilated.
Is it safe to wear clothes that had mold but are now clean?
Yes, once clothes are washed in hot water with vinegar or bleach and completely dried, they are safe to wear. The mold spores are killed by heat and the cleaning agents. However, if you have respiratory sensitivities or mold allergies, you may want to wash them a second time to be certain.
Can I use a steam cleaner on moldy clothes instead of washing?
Steam can kill some mold spores, but it does not remove the mold itself or the musty smell as effectively as washing. Use a washing machine with vinegar or bleach for the best results. Steam cleaning is better suited to furniture and carpets, not fabric clothing.
