How to Remove Musty Smell from Wooden Furniture

Removing the musty smell from wooden furniture means dealing with two issues at once: the dampness that sustains it and the odour trapped in the wood’s pores, drawers, gaps and back 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 is placed against a cold wall.

Why does wood absorb musty smells so easily?

Wood is porous. Even if it has been varnished, waxed or painted, untreated internal drawers, back panels and poorly ventilated corners can 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 starts with managing moisture. Cleaning is helpful, but leaks, condensation and poor ventilation must be addressed to prevent fresh growth. On porous materials, mould can work its way into gaps, making it harder to remove completely.

Which home solution neutralises the odour without harming 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 reduces odour without being as harsh as stronger products.

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

How should you clean drawers, doors and shelves?

Remove clothes, papers and other items before you start. Vacuum or wipe with a dry cloth to clear away dust, then clean the interior sections using the diluted solution. Always follow the wood grain and do not allow liquid to collect 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 can draw out lingering odours once the surface has been cleaned and the wood is dry.

How many times should the process be repeated?

For a slight smell, one careful clean followed by 48 hours of ventilation is usually enough. For furniture that has been shut for months, repeat the cleaning and absorption cycle up to three times, always allowing it to dry completely 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 expose the furniture to indirect sunlight.
• If the odour remains: repeat the cycle one or two more times.
• If there are deep stains or soft wood: consider restoring or disposing of the piece.

How to seal wood so the musty smell does not return

Once the furniture is dry and free from a strong odour, you can strengthen its protection with wax, a wood-specific oil, varnish or a sealer suitable for the original finish. This closes some of the pores, limits moisture absorption and makes future cleaning easier.

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