How to Remove Musty Smells From Old Furniture and Books
Banish that classic basement and attic odor from drawers, cabinets, and old books using airing, absorbers, and enzymatic cleaners.
Published March 28, 2026
That unmistakable musty smell clings to furniture and books that have spent years in damp basements and stuffy attics. The good news is that odor sits on surfaces and in fibers, so airing, absorbers, and the right cleaner usually clear it without harming the piece.
What you will need
- A dry, ventilated space or sunny outdoor spot
- Activated charcoal or baking soda
- Open bowls or breathable cloth pouches
- An enzymatic cleaner for fabric and porous surfaces
- Clean cloths and a soft brush
- Sealable bags or a bin for book treatment
Step 1: Air it out first
Move the piece to a dry, breezy spot, open every drawer and door, and let air circulate for a few days. Indirect sunlight helps, but keep finished wood and book spines out of harsh direct sun to avoid fading.
Step 2: Absorb lingering odor
Place bowls of activated charcoal or baking soda inside drawers and cabinets and close them up. Leave the absorbers in place for several days, replacing them until the smell fades. For books, seal them in a bin with charcoal rather than dusting powder on the pages.
Step 3: Treat porous surfaces
For interiors that still hold odor, wipe lightly with a cloth dampened in enzymatic cleaner, which breaks down odor-causing residue instead of masking it. Test in a hidden spot first and avoid soaking the wood.
Step 4: Keep it dry
Dry everything fully and store with a small desiccant or charcoal sachet to stop the smell returning.
Tip: Resist the urge to spray heavy perfumed deodorizers. They only cover the problem, and the musty note returns once they fade.
Frequently Asked Questions
Why does old furniture smell musty? +
The smell comes from mildew and trapped moisture residue absorbed into wood and fabric over years in damp storage. Removing the source odor, not masking it, is what clears it for good.
Does baking soda or charcoal work better? +
Both absorb odor well. Activated charcoal tends to work faster in enclosed drawers and cabinets, while baking soda is cheap and effective over a longer period.
How do I deodorize old books without damaging them? +
Seal the books in a bin with activated charcoal nearby rather than applying anything to the pages. Give it several days and repeat if needed.
