The short answer
Musty smell in clothes comes from one of three places: loads left wet in the washer, clothes stored before fully drying, or a machine that needs cleaning. Diagnose which, rewash with a full enzyme dose, dry completely, and run an empty hot washer cycle to clear the source.

Find the source
Musty smell has exactly three homes: loads that sat wet in the washer, clothes stored before fully drying, or a machine that itself needs cleaning. Smell a freshly washed item straight out of the dryer. If it is musty already, the washer or the wash is the problem. If it turns musty in the closet, storage moisture is.
The reset protocol
Rewash affected clothes with a full dose of enzyme detergent and dry them completely, no exceptions. Run an empty hot cycle in the washer to clear residue and buildup, and leave the door open between loads so the drum dries out. From there, the no-residue Clean Guy formula plus complete drying keeps must from re-establishing.
Front-loaders, the usual suspect
If the must keeps returning despite good habits, look at the machine itself, especially a front-loader. The door gasket traps water and detergent residue, building a biofilm that re-contaminates every load it touches. The tells: a swampy smell from the empty drum, black flecks on the gasket fold, and clothes that smell off straight out of the wash. The cure is mechanical and cheap: wipe the gasket fold, run an empty hot cycle, leave the door open between loads, and switch to a low-residue formula so the film has nothing to rebuild from.
Mistakes that bring the must back
Relapses follow a known script. Fixing the clothes but not the machine, so the gasket biofilm re-contaminates the very first load. Masking with heavier fragrance, which produces the distinctive musty-plus-perfume signature everyone recognizes and no one mentions. Closing the washer door between loads, which incubates the next colony in the trapped humidity. And trusting the dryer's timed cycle over your own hands: if a waistband or hood feels even slightly cool and damp, it is not done. The permanent fix is the full loop, clothes rewashed, machine serviced, door left open, transfers prompt, and the must has nowhere left to live.
The full reset
- Rewash the affected clothesFull enzyme dose, normal cycle, then dry completely without exception.
- Service the machineWipe the gasket, run an empty hot cycle, leave the door open after.
- Fix the dwell habitMove loads to the dryer promptly. Wet sitting time is where must is born.

Good to know
Why do my clothes smell musty after washing?
Either the load sat wet in the machine, the clothes were stored before fully drying, or the washer itself needs a cleaning cycle. All three are fixable this week.
How do I get mildew smell out of clothes?
Rewash with a full dose of enzyme detergent and dry completely. Stubborn items may need a second wash before the smell fully releases.
How do I stop my washer from smelling?
Run an empty hot cycle periodically, leave the door open between loads, and use a low-suds, no-residue detergent so buildup never accumulates.
Does scent cover up musty smell?
No, and it should not. Kill the must at the source first; fragrance belongs on genuinely clean fabric, not on top of a problem.
Why does only some of my laundry smell musty?
Thick items like hoodies and towels dry slowest, so they are the first casualties of short dryer cycles and damp folding. The thin stuff survives the same bad habit.
Will vinegar or baking soda fix musty laundry?
A full-dose enzyme wash and complete drying outperform both. Home remedies mask or mildly neutralize; removing the residue and moisture removes the cause.
How long does it take to fully eliminate musty smell?
Usually one focused weekend: rewash the affected clothes, service the machine with an empty hot cycle, and dry everything completely. Stubborn thick items may need a second wash, but the source is gone the same day the machine is.
