Musty smells come from mold, mildew, dust and trapped odors. The approach depends on the material.

Air it out

Airing items outdoors in shade on a dry day is the first step for most materials.

Clothing

Wash washable fabrics gently; add white vinegar to rinse for some fabrics (test first). See caring for vintage clothing.

Books and paper

Place books in a sealed container with baking soda or activated charcoal, not touching the pages, for days to weeks.

Furniture

Clean surfaces, air out drawers, and place charcoal or baking soda inside.

Luggage

Vacuum, clean linings, air out, and use charcoal.

Ozone treatment

Ozone can remove stubborn odors but can damage some materials and is hazardous to breathe. Use professionals.

Find and fix the cause first

Musty smells usually mean mold or mildew, which grows in damp, dark, still air. Before treating, inspect the item for visible mold spots, water stains and dampness. Treating odor without drying the item or moving it out of a damp environment just brings the smell back. Keep treated items in a dry, ventilated space.

Safety with mold

Wear gloves and a mask when handling moldy items, and work outdoors when possible. Brush off surface mold outdoors so spores don't spread indoors. Items with extensive mold, or valuable items, may need a professional conservator. People with allergies or respiratory conditions should be especially careful.

Sunlight: helpful but risky

Brief, indirect sunlight helps dry items and reduce odors, and UV has some effect on mildew. But direct sun fades dyes, yellows paper and damages leather and fabrics. Use shade or short exposures, and don't sun valuable or colorful items.

Leather items

For leather goods like bags, jackets and luggage, wipe surfaces with a leather cleaner, air in shade, and place an odor absorber inside. Condition the leather afterward to prevent drying. Avoid soaking leather or using vinegar on it without testing. See best vintage luggage.

Wood furniture and trunks

Remove drawers and air them in shade. Wipe interiors with a mild cleaner, dry thoroughly, and leave containers of baking soda or activated charcoal inside for a week or more. Unfinished wood inside drawers holds odors; some restorers seal interior surfaces with shellac to lock in residual smells. See how to restore vintage furniture.

Patience pays

Stubborn odors can take weeks to fade. Repeat airing and absorbing cycles, refreshing baking soda or recharging charcoal in sunlight. Avoid masking smells with perfumes or fabric sprays, which combine with musty odors rather than removing them.

Musty glassware and ceramics

Glass and glazed ceramics rarely hold odors themselves, but dust and residue do. Wash in warm soapy water, avoiding the dishwasher for delicate or painted pieces.

Baking soda methods

Baking soda absorbs odors and is safe for most items when used indirectly. For books, place them in a sealed plastic box with an open container of baking soda, not touching the pages, for a week or more. For fabric items that can't be washed, lay them flat, sprinkle baking soda lightly on sturdy fabrics, leave overnight and vacuum gently with a brush attachment, testing first on an inconspicuous area. For drawers and trunks, leave an open container inside and replace it every week or two.

Activated charcoal

Activated charcoal absorbs odors more aggressively than baking soda and doesn't leave residue when kept in its bag. Place charcoal bags in drawers, trunks, suitcases and sealed containers with items. Many charcoal bags can be recharged by placing them in sunlight. It's slow but safe and effective over time.

Vinegar for washable fabrics

For washable, colorfast fabrics, a rinse with diluted white vinegar can help neutralize odors. Test first for color bleeding. Don't use vinegar on silk, acetate or delicate dyes without testing, and never mix vinegar with bleach. Rinse thoroughly and air dry in shade.

When to call a professional

Valuable antiques, rare books, fine textiles and items with extensive mold should go to a professional conservator or restoration service. They can clean and deodorize safely without damaging materials or value.

Preventing musty smells in the first place

Store vintage items in a dry, ventilated place, not sealed plastic in a damp basement. Use breathable storage, silica gel packs or a dehumidifier in humid climates, and check stored items regularly. Clean items before storing them; residue and body oils feed mildew. Good storage prevents most odor problems before they start.

Cleaning vintage suitcases and trunks

Vintage luggage often carries the strongest odors, since it spent years in attics and basements. Empty it completely, vacuum linings, wipe hard surfaces, and air it open in shade for several days. Paper linings may need replacement if stained or moldy. Leave charcoal inside between uses.

Musty records and album jackets

Records themselves can be cleaned, but jackets and paper sleeves absorb odors. Replace inner sleeves, air jackets in a dry room and store them near an odor absorber. Keep musty jackets away from the rest of your collection until they're treated to avoid spreading mildew.

Timeline expectations

Light odors may fade after a few days of airing. Stronger odors take weeks of repeated airing and absorbing. Deep-set odors in porous materials may never disappear completely, but can be reduced significantly.

Our bottom line

Dry it, air it, clean what can be cleaned and absorb what's left. Most musty smells fade with patience, and good storage keeps them from coming back.
