How to Remove Musty Smell from Wooden Furniture

Removing the musty smell from wooden furniture means dealing with two issues at once: the moisture that fuels it and the odour trapped in the wood’s pores, drawers, gaps and back panels. Cleaning with mild washing-up liquid, well-diluted white vinegar, bicarbonate of soda and thorough drying can help with 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 when it has been varnished, waxed or painted, unfinished drawer interiors, raw back panels and poorly ventilated corners can hold moisture, dust and mould spores. This is why cupboards left shut for a long period often develop an unpleasant smell before any visible marks appear.

Health and environmental bodies stress that controlling mould starts with controlling moisture. Cleaning is useful, but leaks, condensation and poor ventilation must also be resolved to prevent fresh growth. In porous materials, mould can penetrate cracks and crevices, making it harder to remove completely.

Which home solution neutralises 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 solution 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 in a concealed area.
• Do not use undiluted vinegar on waxed, lacquered or very old wood.
• Dry the furniture straight away with a clean cloth, then leave it open in a well-ventilated area.

How should you clean drawers, doors and shelves?

Remove clothing, papers and other items before starting. Vacuum or wipe the surfaces with a dry cloth to lift dust, then clean the internal sections with the diluted solution. Always work in the direction of the 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 odour after the surface has been cleaned and the wood is dry.

How many times should the process be repeated?

For a faint smell, one careful clean followed by 48 hours of ventilation is often enough. For furniture that has been 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 thoroughly.
• Days 2 and 3: keep bicarbonate of soda or activated charcoal inside closed drawers and cupboards.
• Day 4: ventilate with doors open and expose the piece 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 wooden furniture so the smell does not return

Once the furniture is dry and no longer has a strong odour, improve its protection with wax, a suitable wood 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 never used to store damp clothing. If the smell returns quickly, the cause is probably in the room itself: a wall affected by water ingress, high humidity, limited air circulation or the back of the furniture being constantly exposed to condensation.
