Musty almost always means moisture — poor airflow, a damp wall, or clothes put away not-quite-dry. Mask it and it comes straight back; the smell is the symptom.
Get air moving
Closed, stuffed closets trap stale humid air. Airflow is the cheapest, most effective fix there is.
Add a moisture absorber
In a genuinely damp spot, a desiccant pulls the humidity that feeds the smell out of the air.
Deodorise, do not just perfume
Bicarbonate of soda absorbs odours rather than covering them, unlike a spray that fades in a day.
Wash and reset what is inside
Fabrics hold the smell, so a fresh closet with musty clothes still smells musty. If the whole room feels off, start broad with decluttering, and give the laundry pile its own system.
What didn't make the list
It perfumes the damp for a day, then the musty smell wins again. Fix the moisture and the airflow, do not mask them.
Pleasant, but they do nothing about the underlying damp that causes the smell. Use them after you have dealt with the moisture, not instead.
Questions people ask
Almost always trapped moisture and poor airflow — a damp wall, condensation, or clothes stored slightly damp. Clean fabrics will still smell musty in a humid, stuffy space.
It can be an early sign of damp that mould likes, so it is worth checking. Improve ventilation and absorb the moisture; if you see actual mould, deal with that directly.
