Wash washable thrifted clothes with detergent, treat the odor with white vinegar or baking soda when the care label permits it, and dry every item completely in fresh air. Musty smells usually come from trapped moisture, mildew residue, smoke, or long storage in a closed space.
A musty thrift store smell in clothes can often be removed without harsh chemicals. Start with the fabric type, then use a mild cleaning method that won’t damage the garment.
How to Get Rid of Musty Thrift Store Smell in Clothes: A Safe Step-by-Step Method
Read the care label before doing anything else. Inspect the garment for mold spots, damp seams, stains, pest damage, or weakened fabric. Then test any treatment on an inside hem or other hidden area.
Next, pretreat the odor, wash with the warmest water the label allows, rinse thoroughly, and dry the garment fully. Several mild steps work better than masking the smell with perfume or fabric spray. Never mix vinegar with chlorine bleach or ammonia.
Check the Fabric and Odor Before You Treat the Clothing
Cotton, linen, polyester, and denim are usually sturdy enough for normal machine washing. Wool, silk, leather, suede, rayon, and dry-clean-only clothing need more care. Follow the garment’s label even when the fabric itself seems washable.
Look closely at collars, underarms, waistbands, pockets, and seams. These areas often hold the strongest odor because they dry slowly. Before using vinegar, detergent, rubbing alcohol, or stain treatment, test it on a hidden spot and wait for the fabric to dry.
Wash Musty Clothes With Detergent and a Vinegar Rinse
Use regular laundry detergent because odor treatment alone won’t remove body oils, dust, and grime. For a standard load, add about 1 cup of distilled white vinegar to the rinse compartment, adjusting for your washer and the garment label. Vinegar can reduce odors, but it doesn’t replace detergent or disinfect every type of contamination.
Wash on the warmest setting the fabric can safely handle, and don’t overcrowd the washer. Clothes need water and movement to release residue from the fibers. If an odor remains after washing, run an extra rinse or wash the item again before drying.
Use Baking Soda for Odor Absorption
For sturdy, washable fabrics, add about 1/2 cup of baking soda to the wash according to your machine’s instructions. Baking soda can help neutralize stale or smoky odors, especially in cotton, denim, and polyester. It doesn’t replace washing or guarantee that mildew has been removed.
Check the care label and washer manual before adding powders. Avoid piling several treatments into one cycle, since detergent, vinegar, and baking soda each work differently. Choose the mildest method that fits the garment.
Try a Longer Soak for Sturdy, Washable Fabrics
Soak washable cotton, linen, or synthetic clothing in cool or lukewarm water with detergent for 30 minutes to 2 hours. Then wash the garment as usual and dry it promptly. A second wash is safer than moving to stronger chemicals.
Don’t soak wool, silk, leather, suede, or items with unstable dyes unless the care instructions allow it. Long soaking can shrink fibers, loosen dyes, or distort a garment’s shape. If the water changes color, stop the soak and rinse the item.
Air Out and Dry Thrifted Clothes Completely
Before washing, hang the garment outdoors or in a bright, well-ventilated room for several hours. Leave space between items so air can move around the fabric. Fresh air helps release storage odors, although it can’t clean visible mold or heavy contamination.
After washing, dry clothes immediately. Use a dryer only when the label allows it, or air-dry indoors with a fan or dehumidifier. Check collars, cuffs, waistbands, pockets, and thick seams before folding, because even slight dampness can bring the musty odor back.
Handle Delicate and Dry-Clean-Only Clothes Carefully
Air out wool, silk, rayon, structured jackets, and dry-clean-only garments before treating them. Brush away loose dust with a soft clothing brush, then take the item to a professional cleaner if the odor remains. Tell the cleaner the garment has a musty smell so they can choose an appropriate process.
Hot water, soaking, vinegar, and baking soda can damage delicate fibers, dyes, finishes, and tailoring. Don’t treat a care label as a suggestion, especially on vintage clothing. An expensive repair can cost more than the thrifted item.
Treat Leather and Suede Without Household Liquids
Leather and suede absorb moisture easily, so don’t soak them or spray them with vinegar. Air them out away from direct heat, then use products made for leather or suede. A leather-care professional can assess persistent odor, mold, cracking, or discoloration.
Use Odor Absorbers When Washing Isn’t Enough
Place clean, dry clothing in a roomy cardboard box, cotton garment bag, or other breathable storage space. Set an open box of baking soda or a pouch of activated charcoal nearby, without letting it touch the garment. Leave it for 24 to 72 hours.
Keep powders and charcoal off the fabric because they can leave marks or residue. Replace the absorber if it becomes damp. These products can reduce lingering odor, but they won’t fix active mold, wet clothing, or a contaminated closet.
Know When to Repeat Treatment or Discard the Garment
Repeat the wash-and-dry process once or twice for a mild smell. Stop treating the item if the odor persists after thorough cleaning or returns immediately after drying. That result often points to contamination inside thick padding, seams, or damaged fibers.
Avoid wearing clothing with visible mold, spreading discoloration, a damp interior, or an odor that causes breathing or skin symptoms. Document the issue and ask the thrift store about its return policy when appropriate. Some finds aren’t worth bringing into your closet.
Final Check Before Wearing or Storing
Inspect the garment, follow its care label, wash it with detergent, use one suitable odor treatment, and dry it completely. Delicate fabrics and visible mold need professional handling rather than stronger home remedies.
Store only fully dry clothing in a clean area with airflow. Dry storage keeps thrifted clothes smelling fresh long after the first wash.
