Finding black mold on clothing — a forgotten gym bag, a flooded closet, a damp basement storage bin — is unpleasant but usually fixable. The approach is straightforward: brush off loose growth outdoors, pretreat the stains, wash in the hottest water the fabric allows, and dry completely. Some garments come back fully; heavily embedded growth on delicate fabric may not. This guide summarizes EPA and CDC guidance current as of 2026 and is informational only; consult a physician about health symptoms and a certified professional for larger mold problems in the home.

How to Get Black Mold Out of Clothes, Step by Step

The core method works for most washable cottons and synthetics. Start outdoors to avoid spreading spores inside. Brush or shake off loose surface mold while wearing an N95 respirator and gloves, since disturbing growth releases spores. Pretreat the stained areas, then run the garment through the hottest wash cycle the care label permits, and dry it thoroughly — ideally in sunlight or a hot dryer, because residual dampness invites regrowth.

The underlying principle mirrors all mold cleanup: remove the growth and remove the moisture. Clothes mildew in the first place because they sat damp, so the lasting fix includes correcting whatever kept them wet. Our broader mold inspection and testing hub covers how chronic dampness in closets and basements feeds these problems.

Pretreatment Options Compared

Before washing, treat the stained area. Several household agents work, each with trade-offs.

White vinegar

Gentle and widely effective. Soak the affected area in undiluted white vinegar for an hour, or add a cup to the wash. Vinegar handles surface mold and odor on most fabrics with low risk of damage, making it a good first choice for colored and delicate items.

Borax or baking soda

Dissolved in warm water, these provide a mild alkaline boost and help with odor. Borax is a common laundry additive for mildew; baking soda is gentler and safe for most fabrics.

Hydrogen peroxide

About 3% peroxide can lift mold and stains, but test it on a hidden seam first because it has a mild bleaching effect on colors.

Chlorine bleach

Effective on white, bleach-safe cottons but unsuitable for colors, wool, silk, spandex, or many synthetics. The CDC notes bleach is not required for mold cleanup, and on clothing its main role is stain and color removal on whites. Never mix it with ammonia-based products.

Washing and Drying That Actually Kills Growth

Heat and thorough drying are the workhorses. Wash at the hottest temperature the care label allows — hot water removes mold and odor far better than cold. Add your chosen pretreatment agent to the cycle, and consider a second rinse. If the musty smell lingers after washing, repeat before drying, because drying in heat can set odors that remain.

Drying matters as much as washing. Line-drying in direct sun adds a natural assist, and a hot dryer ensures no residual moisture stays in seams and waistbands. Putting a still-damp garment back in a drawer is the most common reason mildew returns. For badly affected loads, run an empty hot cycle with vinegar afterward to clean the washer drum, which can otherwise harbor spores.

Delicate, Wool, and “Dry Clean Only” Garments

Not everything tolerates hot water and bleach. Wool, silk, leather, and structured garments need gentler handling. For “dry clean only” items, brush off loose growth outdoors and take them to a professional cleaner, telling them specifically that the issue is mold so they can treat it appropriately. For washable delicates, cold-water vinegar soaking and air drying is the safest route, accepting that results may be partial. Leather can sometimes be wiped with a diluted vinegar solution and dried, but persistent growth in leather or suede often means the item is beyond saving.

When Clothing Can’t Be Saved

Some items aren’t worth the effort or the health risk. Heavily colonized fabric — where growth has penetrated deep into fibers, padding, or stuffing — may never fully clean, and repeated washing won’t remove embedded staining or odor. Items that sat in sewage-contaminated or flood water are generally discarded rather than laundered, in line with EPA guidance on contaminated porous materials. For anyone with asthma, allergies, or a weakened immune system, the CDC advises caution; if a garment requires extensive handling of mold, discarding it may be the safer call. Sentimental pieces can be professionally restored, but set expectations realistically.

Why Clothes Got Moldy and How to Prevent It

Clothing molds because it stayed damp long enough for spores to germinate — wet laundry left in the machine, sweaty clothes in a closed hamper, items stored in a humid basement, or a closet against a cold exterior wall that sweats. Prevention follows the moisture rule. Don’t let wet laundry sit; move it to the dryer promptly. Keep closets and storage areas ventilated and below about 50% humidity, using a dehumidifier in damp basements. Store seasonal clothing clean and fully dry in breathable containers, not sealed plastic that traps moisture. If a closet repeatedly grows mildew, the wall or humidity behind it is the real issue — our guide on condensation and growth on cold surfaces explains that mechanism.

Is the Mold on Clothes Actually “Black Mold”?

People often call any dark growth on fabric “black mold,” picturing the toxic-mold headlines. In reality, the dark spots on clothing are usually ordinary mildew or one of many common molds that thrive on damp cellulose, not necessarily the Stachybotrys species popularly labeled “toxic black mold.” For the purpose of cleaning your clothes, the species doesn’t change what you do: brush off, pretreat, wash hot, and dry fully. The CDC advises treating any indoor mold the same way regardless of color or type, because all of it signals a moisture problem and can affect sensitive people.

What the color and extent do tell you is how aggressive to be. Light surface mildew on a recently damp shirt usually launders out completely. Heavy, deeply colored growth that has penetrated fibers, padding, or stuffing may resist cleaning and warrant discarding the item. Rather than trying to identify the species, focus on how deep the growth goes and how the fabric responds to laundering. If the staining and odor persist after careful washing, the practical answer is the same whether or not it was technically “black mold”: the item may be beyond saving.

Acting Quickly: Why Timing Matters

The sooner you treat moldy clothing, the better the odds of full recovery, because mold roots deeper into fibers the longer it grows. A shirt discovered moldy after a day or two in a damp gym bag usually launders clean; a box of clothes left in a humid basement for a season may have growth embedded too deeply to remove. This is the same principle that governs all mold cleanup — early action on the moisture and the growth prevents a small problem from becoming permanent damage.

If you can’t wash moldy items immediately, get them dry and isolated in the meantime. Move them out of the damp environment, ideally into sunlight or a dry, ventilated space, and keep them separate from clean laundry so spores don’t transfer. Drying halts active growth even before you launder, buying time without letting the problem worsen. Bagging heavily moldy items in plastic until you can treat them also limits spore spread through the house. The worst approach is leaving damp, moldy clothes piled together, which lets growth advance and spread to neighboring garments.

Removing the Musty Smell That Lingers

Sometimes clothes come out visually clean but still smell musty, which means odor-causing residue or spores remain in the fibers. Several approaches help. A pre-soak in a solution of one cup white vinegar per gallon of warm water for an hour breaks down odor before washing. Adding half a cup of baking soda to the wash, or a cup of borax, boosts deodorizing. For stubborn cases, washing twice before drying — because heat can set odor permanently — often does the trick. Sunlight is a natural deodorizer and mild disinfectant, so line-drying outdoors when possible helps finish the job.

If the smell persists after multiple washes, the source may be the washing machine itself. Front-loaders in particular harbor mold in the door gasket and detergent drawer. Run an empty hot cycle with two cups of vinegar or a washer-cleaning tablet, wipe the gasket, and leave the door open between uses so the drum dries. A moldy machine will re-contaminate every load no matter how carefully you treat the clothes.

Handling Different Fabric Types Safely

Matching the method to the material prevents ruining the garment while removing the mold. Cotton and sturdy synthetics tolerate hot water and most treatments, making them the easiest to recover. Bright colors and prints should avoid chlorine bleach; use vinegar or a color-safe oxygen bleach instead, and test peroxide on a hidden seam first. Wool and silk need cool water, gentle handling, and air drying; harsh agents and heat can shrink or damage them. Leather and suede can sometimes be wiped with a cloth dampened in diluted vinegar, then dried away from direct heat, but deep growth often means the item is beyond saving. Structured or “dry clean only” garments should go to a professional cleaner with a clear note that the issue is mold, so they treat it appropriately rather than just pressing it.

Protecting Yourself While Cleaning Moldy Clothes

Disturbing moldy fabric releases spores, so basic protection matters even for laundry. The EPA and CDC recommend at least an N95 respirator and gloves when handling visibly moldy material, and doing the initial brushing or shaking outdoors keeps spores out of the house. Avoid shaking moldy clothes inside, which spreads spores across surfaces and into the air you breathe. Wash your hands afterward, and launder any cloths or gloves used in the process. People with asthma, allergies, or weakened immune systems should have someone else handle heavily molded items, since the CDC notes those groups are more vulnerable to exposure during cleanup.

When to Call a Professional

Laundering clothes is a do-it-yourself task, but the conditions that molded them sometimes aren’t. If clothing keeps growing mold in the same closet or storage area, if you find growth larger than about 10 square feet on nearby walls, or if the dampness traces to a leak or chronic basement humidity, a professional should assess the moisture source. Treating the clothes without fixing the room guarantees a repeat. For medically vulnerable household members, professional handling of any significant mold is the safer path.

Treating Bedding, Towels, and Soft Goods

The same principles extend beyond clothing to bedding, towels, curtains, and other washable soft goods, which mold for the same reason — they stayed damp. Towels left wadded and wet are a frequent culprit, growing mildew and the characteristic sour smell within a day or two. Treat them as you would clothes: pretreat with vinegar or an oxygen bleach, wash in the hottest water the fabric allows, and dry completely, repeating before drying if odor lingers. Heavily colonized pillows, mattress toppers, and stuffed items with internal padding are harder, because growth penetrates the filling where laundering can’t reach; these are often discarded rather than salvaged.

Prevention mirrors the clothing advice. Hang towels to dry fully between uses rather than leaving them bunched, wash bath mats and shower curtains regularly, and keep linens stored in a dry, ventilated space rather than a humid closet or basement. In damp storage areas, a dehumidifier holding humidity below about 50% protects everything stored there. As with clothing, recurring mold on soft goods in a particular room points back to a moisture problem in that space, which is the real thing to fix.
