How to Remove the Musty Smell from Wooden Furniture

Removing the musty smell from wooden furniture means dealing with two issues at once: the dampness that sustains the problem and the odour trapped in the wood’s pores, drawers, gaps and backing panels. Cleaning with mild washing-up liquid, properly diluted white vinegar, bicarbonate of soda and thorough drying can help in mild cases, but the smell will return if the wood remains damp or stands against a cold wall.

Why does wood absorb musty smells so easily?

Wood is porous. Even if it has been varnished, waxed or painted, internal drawers, unfinished backs and poorly ventilated corners can still hold moisture, dust and mould spores. This is why cupboards left closed for long periods often develop an unpleasant smell before visible marks appear.

Health and environmental bodies stress that controlling mould begins with moisture: cleaning is useful, but leaks, condensation and inadequate ventilation must be addressed to prevent further growth. In porous materials, mould can penetrate cracks and may be harder to remove completely.

Which home solution neutralises odour without damaging the finish?

For wooden furniture, the safest approach is to avoid soaking it. Mix 500 ml of warm water with 1 teaspoon of mild washing-up liquid and 2 tablespoons of white vinegar. This removes the surface film and lessens odour without being as harsh as stronger products.

• Use a cloth that is only lightly dampened, never dripping.
• Test the finish on a hidden area first.
• Do not use undiluted vinegar on waxed, lacquered or very old wood.
• Dry immediately with a clean cloth, then leave the furniture open in a well-ventilated place.

How should you clean inside drawers, doors and shelves?

Remove clothes, papers and other items before cleaning. Vacuum or wipe with a dry cloth to get rid of dust, then clean the interior surfaces with the diluted mixture. Always work in the direction of the grain and do not allow liquid to sit in corners.

Once everything is dry, place an open container of bicarbonate of soda or activated charcoal inside the furniture for 24 to 72 hours. These absorbents do not “kill” mould, but they help draw out lingering odour once the surface has been cleaned and the wood is dry.

How many times should the process be repeated?

For a mild smell, one careful clean followed by 48 hours of ventilation is usually enough. For furniture that has remained closed for months, repeat the cleaning and absorption cycle up to three times, always allowing it to dry fully between applications.

• Day 1: clean with washing-up liquid and diluted vinegar, then dry.
• Days 2 and 3: leave bicarbonate of soda or activated charcoal inside closed drawers and cupboards.
• Day 4: ventilate with doors open and place the furniture in indirect sunlight.
• If the odour remains: repeat the cycle once or twice more.
• If there are deep stains or the wood feels soft: consider restoring or disposing of the piece.

How to seal wood so the musty smell does not return

Once the furniture is dry and no longer has a strong odour, protection can be improved with wax, a wood-specific oil, varnish or a sealer compatible with the original finish. This step closes some of the pores, limits moisture absorption and makes future cleaning easier.

The result will last longer if the furniture is kept a few centimetres away from the wall, aired weekly and not used to store damp clothes. If the smell returns quickly, the source is probably the room itself: a wall with water ingress, high humidity, limited air circulation or the furniture’s backing panel constantly exposed to condensation.
