Mold on clothes comes off with vinegar, bleach, or borax depending on the fabric

The method you use depends on whether the fabric is white or colored, how delicate it is, and how much mold is present. For most washable clothes, white vinegar kills mold spores and removes the stain without bleaching colored fabrics. For white cotton or linens you don't mind bleaching, chlorine bleach works faster and more thoroughly. Borax is a gentler alternative that works on most colors and is less harsh than bleach. The key is treating the mold before you wash—putting moldy clothes directly in the washer can spread spores through the machine.

If the mold has been on the fabric for weeks or has created a large dark patch, the stain may not come out completely, but the mold itself (the living fungus) will die with any of these treatments. Mold that has eaten into the fibers deeply may leave a permanent discoloration even after the spores are dead.

Key Takeaways

  • White vinegar works on most colored fabrics and kills mold without bleaching; use one cup per load or spray it directly on the stain.
  • Chlorine bleach is the fastest option for white fabrics but will damage or discolor anything else.
  • Borax is gentler than bleach and safe for colors; mix it with water to make a paste or add it to your wash cycle.
  • Always air-dry treated clothes in sunlight if possible, because UV light kills remaining spores and prevents regrowth.
  • Mold returns when clothes stay damp or in humid, poorly ventilated spaces—store clean, dry clothes in breathable containers in a dry room.

Treating mold with white vinegar

Vinegar is safe for almost all fabrics and is your first choice if you are unsure about the material. Fill a spray bottle with undiluted white vinegar and spray the moldy area until it is wet. Let it sit for one hour, then brush away any visible mold with an old toothbrush or soft brush. Rinse the spot with clean water and wash the garment normally.

For a heavier infestation, soak the entire garment in a mixture of one part white vinegar to one part water for one to two hours before washing. This works especially well for clothes that have been stored damp or in a closed bag. The vinegar smell fades as the clothes dry.

Using bleach on white and colorfast fabrics

Chlorine bleach kills mold spores faster than vinegar and removes stains more completely, but it will damage or discolor anything that is not white or explicitly colorfast. Test bleach on a hidden seam or inside hem first if you are uncertain. Mix one cup of bleach with one gallon of water and soak the garment for five to ten minutes, then wash it when ready in hot water. Do not let bleach sit on fabric longer than ten minutes.

For spot treatment, dilute bleach more heavily—one part bleach to ten parts water—and explore it with a cloth to the moldy area only. Rinse thoroughly with water before washing. Bleach is harsh on elastic and delicate fibers, so avoid it on swimwear, athletic wear, or anything with spandex.

Borax as a gentler alternative

Borax is a mineral-based cleaner that kills mold and is safe for most colors and delicate fabrics. Mix one-half cup of borax with two cups of warm water to make a paste, explore it directly to the moldy spot, and let it sit for ten minutes. Scrub gently with a soft brush, rinse with clean water, and wash normally. You can also add one-half cup of borax directly to your washing machine along with your regular detergent for a full-load treatment.

Borax works more slowly than bleach but is less likely to damage fabric or cause allergic reactions. It is safe to use on wool, silk, and other delicate materials. Wear gloves when handling borax powder, and rinse your hands after use.

Drying and preventing regrowth

After treatment, hang the clothes to air-dry in direct sunlight if possible. Sunlight and UV rays kill remaining mold spores and prevent the mold from returning. If you must use a dryer, use the highest heat setting safe for the fabric. Never put treated clothes away while they are still damp—mold will return within days.

Once the clothes are completely dry, store them in a breathable container (cotton bags or cardboard boxes work well) in a cool, dry room. Plastic bins trap moisture and create the humid environment mold needs to grow. Keep the storage area well-ventilated and check it monthly, especially during humid months. If you live in a very humid climate, consider placing a small container of baking soda or silica gel packets in the storage area to absorb excess moisture.

When to discard clothes instead of treating them

If mold has covered more than half the garment, has been present for several months, or has created a smell that does not fade after treatment, the fabric may be too damaged to save. Mold that has penetrated deep into the fibers can weaken them permanently, and some mold species produce toxins that can irritate skin even after the spores are dead.

If you have a respiratory condition, asthma, or a mold allergy, err on the side of caution and discard heavily molded clothing rather than treating it. The risk of inhaling spores during cleaning is not worth the cost of replacing a single garment. For clothes with sentimental value, take them to a professional dry cleaner who has equipment to treat mold safely.

Preventing mold in your closet and storage

Mold grows in closets and storage spaces when humidity is high, air does not move, or clothes are stored while damp. Keep your closet door open regularly to allow air circulation, especially in bathrooms or basements where humidity is naturally higher. Wipe down shelves and rods monthly with a dry cloth to remove dust and spores before they settle.

Never store clothes that are not completely dry. Wash and dry them fully, then wait a few hours before putting them away. If you live in a humid climate, run a small dehumidifier in your closet or storage room, or place open containers of baking soda on shelves to absorb moisture. Check stored clothes every few weeks during humid seasons—catching mold early makes treatment much easier.

Frequently Asked Questions

Can I wash moldy clothes with other clothes in the same load?

No. Washing moldy clothes with clean clothes spreads mold spores throughout the machine and onto other garments. Always treat and rinse the moldy item separately first, then wash it alone or with other heavily soiled items. Run an empty hot-water cycle with one cup of vinegar or bleach after washing moldy clothes to clean the machine.

Will mold come back after I treat it?

Only if the clothes become damp again or are stored in a humid space. Mold spores are everywhere in the air, but they only grow when fabric stays wet or damp for more than 24 to 48 hours. Dry your treated clothes completely in sunlight, store them in a breathable container in a dry room, and check them monthly. If mold returns, the problem is moisture in your storage area, not the treatment.

Is it safe to wear clothes after treating them for mold?

Yes, once they are completely dry and the smell is gone. Wash them one more time after treatment to remove any remaining vinegar, bleach, or borax residue. If you have mold allergies or asthma, wear a mask while treating the clothes and wash your hands thoroughly afterward. If the mold smell returns after wearing the clothes, the treatment did not fully kill the spores and you should treat them again.

What is the difference between mold and mildew on clothes?

Mildew is a type of mold, so the treatment is the same. Mildew appears as a thin, powdery white or gray coating, while mold is usually darker, thicker, and may have a musty smell. Both are fungi that need moisture to grow, and both respond to vinegar, bleach, or borax. The treatment method does not change based on which type it is.

Can I use hydrogen peroxide to remove mold from clothes?

Yes, hydrogen peroxide works on mold and is safe for most fabrics. Mix equal parts hydrogen peroxide and water, spray it on the moldy area, and let it sit for ten minutes. Scrub gently and rinse with clean water. It is less harsh than bleach but less effective than vinegar on heavy infestations. Test it on a hidden area first, as it can lighten some dyes.
