Musty smells in any surface indicate the presence of mold. If your wooden furniture has a musty smell, it may be harboring mold. Left alone, these fungi continue to spread and can even transfer to other pieces of furniture. The musty smell is unpleasant and the presence of mold can become unhealthy. In order to remove the odor, you must also get rid of the mold spores.
Fill a bucket with white vinegar. Wet a clean cloth with the vinegar and wipe down your wooden furniture. Vinegar is a natural mold-killer and deodorizer.
Sprinkle baking soda onto a damp sponge. Rub the sponge onto the furniture. Baking soda is a gentle cleanser that absorbs unpleasant odors.
Rinse your sponge with warm water and wipe off the furniture to remove the baking soda. Dry the furniture with a clean, dry cloth.
Bring your wood furniture outside, if possible, and place it in the sun. Allow the furniture to dry outdoors to kill any remaining mold and deodorize the wood.
