How to get musty smell out of clothes after rainy commutes (and keep it out)

Rain does not make clothes smell. What grows in them afterwards does. Here is the science behind the damp, sour smell, a rescue wash that actually removes it, how to dry and store clothes in wet seasons, and why perfume should be the last step, never the fix.

If you have ever pulled a jacket out of a bag the morning after a wet ride and wondered how to get musty smell out of clothes for good, you are fighting microbes, not water. Damp fabric that stays damp for hours feeds bacteria and, given longer, mould. Both leave behind smells that a normal wash may not shift. This guide explains what is happening in the fibres, gives a step-by-step rescue wash, covers drying indoors, storage and the washing machine itself, and adapts the advice for rainy cities from London to Mumbai. It ends where a fragrance site should: how to smell good once your clothes are clean.

Key takeaways

• The musty smell is mostly bacterial waste, and sometimes mould. Speed of drying is the single biggest factor.
• Research from Japan identified one bacterium, Moraxella osloensis, as a major cause of the classic "wet laundry" smell. It survives drying and needs leftover body soil to make the smell.
• A rescue wash means a hot wash where the label allows, a full dose of detergent, an oxygen bleach soak, a vinegar rinse and fast drying.
• A smelly washing machine re-infects clean clothes. Clean it monthly in wet seasons.
• Never store anything slightly damp, and keep the air around stored clothes dry.
• Perfume over musty fabric makes it worse. Fix the smell first, then add scent to skin.

What the musty smell actually is

People describe it differently: damp, sour, mildewy, "wet dog", old cupboard. The words point to two different culprits, and telling them apart changes the fix.

The wet laundry smell: bacteria

The sour, slightly sweaty smell that appears on clothes that dried slowly is mostly bacterial. In a 2012 study in Applied and Environmental Microbiology, Hiromi Kubota and colleagues at Kao Corporation in Japan, studying smelly towels and T-shirts from Japanese homes, traced the malodour of laundry largely to one compound, 4-methyl-3-hexenoic acid, present only in traces yet the biggest contributor to the smell. The most common bacterial group they isolated, Moraxella osloensis, turned up in 87% of the smelly samples, and the team showed that it made that compound in used towels but not in new ones. In other words, the bacterium needs leftover body soil to feed on.

Two more findings explain why this smell is so stubborn. The bacterium tolerates drying and ultraviolet light, so it can survive a slow dry and keep producing the smell. And the study cited a survey in which 84% of respondents hung laundry indoors, with 63% of those reporting odour problems. That is the rainy-season pattern in a sentence.

The old cupboard smell: mould and mildew

An earthier, cellar-like smell, especially on clothes that sat damp for days or in storage, is more likely mould or mildew. Mould often leaves visible spots: grey, black or green speckles, sometimes with staining. If you see them, you need stain treatment as well as odour removal, and some delicate fabrics will not fully recover.

Why do my clothes smell musty when I sweat?

If a shirt smells fine dry but turns sour the moment you warm up, odour compounds or bacteria are still bound in the fibres. Heat and moisture release them. This is common with synthetic sportswear. In a 2014 Ghent University study in Applied and Environmental Microbiology, 26 people wore cotton and polyester shirts through an hour-long spinning class; a trained odour panel rated the polyester shirts as smellier, and those shirts carried more Micrococcus bacteria, which are linked to unpleasant odours. Our guide to fragrances for gyms and active plans covers the skin side; this guide covers the fabric side.

How to get rain smell out of clothes

Rain itself is clean. What people call "rain smell" on clothes is usually one of three things: city grime and exhaust carried in the water, bacteria growing in fabric that stayed wet, or, on a lucky day, the earthy petrichor from the street. The first two wash out with the method below. The third is one of the few smells worth bottling, and our piece on perfumes that smell like rain explains how.

How to get musty smell out of clothes: the rescue wash, step by step

This is the full method for clothes that already smell. Read the care label first; it overrides everything here.

1. Sort by fabric and colour. Cottons and linens that tolerate heat in one load, synthetics and darks in another, delicates (wool, silk) set aside.
2. Pre-soak in oxygen bleach. Dissolve an oxygen bleach (sodium percarbonate based) in warm water as the pack directs and soak colourfast items for one to several hours. It releases hydrogen peroxide, which breaks down organic soil and odour without the colour damage of chlorine bleach.
3. Wash as hot as the label allows. Towels, bedding and cotton underwear usually tolerate 60°C. Use a full dose of a good detergent; underdosing leaves the body soil the bacteria feed on.
4. Do not overload. Clothes need room to move through the water. A packed drum leaves soil behind.
5. Add vinegar to the rinse, not the wash. White vinegar in the softener compartment helps rinse out detergent and residue. Use it occasionally rather than every wash, and never in the same load as chlorine bleach.
6. Skip fabric softener for this load. Softener coats fibres, which can trap odour and, on sportswear and waterproofs, reduce wicking and breathability.
7. Dry immediately and fast. Take the load out the moment the cycle ends. Tumble dry if the label allows, or hang with space between items in moving air (see the drying section).
8. Smell test when dry, then warm. Smell the garment dry, then breathe on it or hold it in your hands for a minute. If the sour note returns with warmth, repeat steps 2 to 7.

How to get musty smell out of clothes with vinegar

For a mildly musty load, a vinegar rinse alone often works. For a strong smell, use vinegar as a soak: an hour in a sink of cool water with a generous splash of white vinegar, then a normal hot wash. Does vinegar remove musty smell from clothes completely? It helps by dissolving residues and making the environment hostile to some microbes, but it does not replace a proper detergent wash. Think of it as the rinse, not the cure.

How to get musty smell out of clothes with baking soda

Baking soda (sodium bicarbonate) is mildly alkaline and neutralises acidic odours, and the wet laundry smell is acidic. Add a few spoonfuls to the drum alongside detergent, or dissolve some in a soak for items that cannot take heat. Do not add it to the same rinse as vinegar; they cancel each other out in a fizz.

How to get musty smell out of clothes left in washer

If a load sat wet in the drum overnight, rewash it straight away with detergent, on the hottest setting the label allows, then dry it quickly. If it sat for a day or more in warm weather, add an oxygen bleach soak first. This is the most common cause of clothes that smell musty after washing.

How to get mildew smell out of clothes

Mildew needs more than a deodorising wash. Brush off any surface growth outdoors, treat spots with oxygen bleach (or chlorine bleach on white cotton only, following the label), wash hot, and dry in sun and moving air. Wear a mask while brushing if you are sensitive to mould. Heavily mouldy delicates may need a professional cleaner, and some are not worth saving.

Fixes without a full wash

Some things cannot go in a machine: wool coats, structured jackets, some shoes. Here is how to get musty smell out of clothes without washing, in order of effectiveness.

• Sun and wind. Hang the item outdoors on a dry, breezy day. Airflow removes volatile odour, and drying the fibres fully stops further growth.
• Steam. A garment steamer or a hanging in a steamy bathroom loosens odour, but the item must then dry completely in moving air, or you have made it damp again.
• An alcohol mist. A light mist of high-strength, unscented drinking alcohol or plain rubbing alcohol on the inside of a lining, then airing, is a long-standing costume-department trick. Patch test first; alcohol can lift some dyes.
• Baking soda in a bag. Seal the item loosely in a large bag with an open dish of baking soda for a day or two. It absorbs some odour; it will not kill what is growing.
• Professional cleaning. For tailoring, leather and anything precious, this is the safe route.

Does sunlight kill mold?

Sunlight helps, mostly by drying fabric quickly and warmly, and ultraviolet light can damage many microbes on exposed surfaces. But it is not a guarantee: the Kubota study noted that Moraxella tolerates UV, and light does not reach inside thick seams. Treat sun as a strong finishing step, not a substitute for washing.

How to dry clothes indoors without smell

If you search why do clothes dry indoors smell, the answer is time. Slow drying in still, humid air is exactly what the bacteria need. The fix is to shorten drying time.

• Extra spin. Run an additional high spin if the fabric allows. Less water in means faster drying.
• Space, not stacks. Leave a hand's width between items on the rack. Hang shirts on hangers rather than folding them over a rail.
• Move the air. A fan pointed at the rack cuts drying time dramatically. Open a window a little if outdoor air is drier than indoor air.
• Dehumidify. A dehumidifier in a small room both dries clothes and protects the room. The US Environmental Protection Agency advises keeping indoor humidity below 60%, ideally between 30% and 50%, to prevent mould.
• Aim for hours, not days. EPA guidance on water-damaged items is to dry them within 24 to 48 hours; for laundry, aim far shorter, ideally the same day.
• Vent the dryer. A tumble dryer that vents indoors adds the moisture back to the room. Vent it outside where possible.

Why do my clothes smell damp after drying? Usually because they were never fully dry. Thick seams, waistbands and hoods hold water long after the rest feels dry. Feel those parts before you fold.

Clean the washing machine

A musty smell in washing machine drums, door seals and detergent drawers transfers straight back onto clean clothes. Front loaders are especially prone because the rubber door seal traps water and lint.

1. Wipe the door seal, including inside the folds, after the last load of the day.
2. Leave the door and the detergent drawer open between washes so they dry.
3. Pull out and clean the drawer and, if your model has one, the drain filter, following the manual.
4. Run an empty maintenance wash at the hottest setting with a machine cleaner or oxygen bleach once a month in wet seasons.
5. Avoid only ever washing at low temperatures with liquid detergent and softener; it is the classic recipe for buildup.

Storage for rainy seasons

The answer to how to get musty smell out of clothes that have been in storage is the rescue wash above. The better answer is to stop it happening.

• Store only bone-dry, clean clothes. Body soil plus a little humidity is enough to start the smell over weeks.
• Breathable, not sealed. Cotton garment bags beat plastic, which traps moisture. Vacuum bags are fine only for clothes that are completely dry and stored in a dry room.
• Absorb moisture. Silica gel sachets or moisture absorber tubs in wardrobes help in humid climates. Empty or refresh them as they fill.
• Leave a gap. Do not push wardrobes flat against cold outside walls, where condensation forms.
• Air the wardrobe. Open doors on dry days and do not overfill rails.
• Check monthly. In a monsoon or a wet winter, take a quick sniff of the back of the wardrobe each month.

A rainy-commute routine that prevents the smell

Most musty clothes start with one wet commute and one bad hour afterwards. A routine fixes that.

On the way

• Wear a proper rain shell or rain suit over work clothes, and carry work clothes in a waterproof bag or liner.
• Keep a spare pair of socks and a light top at work.

On arrival

• Hang the rain gear open on a hanger, not folded wet into a bag or scooter boot.
• Stuff wet shoes with newspaper and change it at lunchtime.
• Never leave a damp gym kit or towel in a bag. That is where the worst smells start.

At home

• Hang everything to dry on arrival, even if it will be washed later.
• Wash within a day in humid weather.
• Rotate two pairs of shoes so each dries fully between wears.

That is how to remove smell from clothes in rainy season before it ever forms: dry the fabric before the bacteria get going.

How rainy commutes change by city

Smell in clothes during rainy season is a global complaint, but the cause and the fix change with climate and housing.

London

London's problem is persistence rather than downpours: light rain, low winter sun and short days mean laundry often dries indoors on radiators or racks. That adds moisture to small flats and raises condensation and mould risk. A dehumidifier and a fan are often the best laundry investment a London renter can make.

Seattle

Seattle's long, grey, drizzly season means outdoor drying is rarely an option for months, and many homes rely on tumble dryers. Dryers solve the speed problem, so here the musty smell more often comes from the washer, wet gear left in cars, and rain shells packed away damp.

Tokyo

Japan's rainy season, tsuyu, brings around two months of frequent rain in late spring and early summer across much of East Asia. Indoor drying is so common that the laundry smell is a recognised problem there, which is why the Kao study above sampled towels and shirts from Japanese homes. Fans, dehumidifiers and detergents marketed for indoor drying are standard kit.

Hong Kong

Hong Kong has spells of extreme humidity in late winter and spring when walls and floors sweat and nothing seems to dry. In those weeks, closing windows and running a dehumidifier often dries clothes faster than outdoor air, and wardrobes need moisture absorbers.

Singapore

Singapore is hot and humid all year with sudden afternoon storms. Clothes dry fast in sun and wind, but a wet commute in an air-conditioned office or train means clothes stay damp against the skin for hours. A change of top and a waterproof bag liner do more good here than any detergent.

Mumbai and Pune

The southwest monsoon soaks western India for months. In Mumbai and Pune, two-wheeler commuters ride through it daily, often arriving at work with wet trousers and a rain suit that has to dry somewhere. The monsoon guide on Potholes.app has pothole-safe monsoon riding habits for Pune two-wheeler commuters, including a kit list and a blunt warning to hang the rain suit at work rather than folding it wet into the boot. Riders in Pune can also check the Pune pothole map before a monsoon commute and plan around the craters that fill with water.

Fewer soakings: plan the wet route

The fastest way to fewer musty clothes is fewer drenchings. On a bike or scooter, one waterlogged pothole can soak you from the knees down and send road water, with everything in it, into your clothes and shoes.

• Know your water spots. Most routes flood in the same places every year. Walk or ride your route after the first heavy rain and note them.
• Avoid the gutter line. Water collects at the edges, and so does the dirtiest spray.
• Slow down through puddles. Your own spray soaks you as much as passing traffic does.

In Pune and Pimpri-Chinchwad, Potholes.app turns that local knowledge into a shared map. You can pin a waterlogged pothole in Pune with a photo, and follow a flooded pothole on your Pune route until it is fixed as neighbours mark it still there or repaired.

It is an independent Pune road-hazard map run outside government, so it is a public record rather than a complaints desk. In other cities, check whether your council or city runs a road-fault reporting app or website, and report the puddle that keeps soaking you; a fixed road is a drier commute.

Perfume comes last: clean scents for fresh clothes

It is tempting to spray perfume over a jacket that smells a bit off. Do not. Fragrance does not kill bacteria, and musty compounds mixed with perfume produce a sour, stale version of both. Worse, a scent sprayed onto a damp, smelly lining keeps reminding you of it for days.

Once clothes are genuinely clean, scent belongs on skin. Here the fragrance world has an interesting link to your laundry: the "clean" smell of fresh washing is largely synthetic musk. Galaxolide, a synthetic musk with a clean, sweet, musky floral character, has been used in fabric softeners and detergents since the late 1960s, and musks of this kind run through many perfumes too. That is why a clean smelling perfume so often reads as "fresh laundry".

Clean, laundry-like scents to try

• A classic white musk perfume. Jovan White Musk is a long-running, widely available take on the clean musk idea.
• A white, soapy floral. Byredo Blanche is the bottle many wearers name when they want to smell like clean white sheets. To see how the two approaches differ, open Byredo Blanche vs Jovan White Musk side by side, and if Blanche is close but not quite right, browse perfumes similar to Byredo Blanche.
• A fresh fruity floral. Jo Malone English Pear and Freesia is light, crisp and easy in humid weather.
• Search by the notes. Use note search for musk, aldehydes and cotton-like notes, set heavy vanilla or oud to avoid, and explore clean musky profiles in the fragrance accords explorer.

Scent and fabric

• Skin first. Spray on skin, let it dry, then dress. That keeps fragrance off delicate fabrics.
• Fabric holds scent longer. A light mist on a cotton scarf lasts, but oils and dyes in perfume can mark silk and pale fabrics. Test on a hidden seam.
• Mind the office. A damp, crowded office amplifies scent. One spray of something clean is plenty; our piece on office-safe fragrances has the etiquette.

Common mistakes

• Leaving wet loads in the machine. Even a few hours in warm weather is enough to start the smell.
• Underdosing detergent to save money. Leftover body soil is the food source.
• Using more softener to cover the smell. It adds residue and hides nothing for long.
• Mixing chlorine bleach with vinegar or ammonia. Never. Bleach plus an acid such as vinegar releases chlorine gas, and bleach plus ammonia releases chloramine gas. Use them in separate washes.
• Folding "almost dry" clothes. Seams and waistbands finish drying in the drawer, and smell.
• Spraying perfume on musty fabric. It creates a third, worse smell.

If this happens

The smell comes back every time I sweat

Odour is bound in the fibres, common in polyester. Soak in oxygen bleach, wash hot within the label limit, skip softener, and consider cotton or wool for your commute layer.

Only towels smell

Towels hold the most water and body soil. Wash them hot, dry them fully the same day, and do not leave used ones bunched up.

Everything from the machine smells

The machine is the source. Clean the seal, drawer and filter, and run a hot maintenance wash before the next load.

A wool coat smells like a wet dog

Wool smells when wet and usually loses it once fully dry. Hang it in moving air for a day. If the smell remains when dry, take it to a professional cleaner.

There are black spots as well as a smell

That is mould. Treat the stain, wash hot if the fabric allows, dry in sun, and check the room it came from for damp.

FAQ

Why do my clothes smell musty after washing?

Usually they dried too slowly, sat wet in the machine, or the machine itself is dirty. Bacteria such as Moraxella osloensis survive the wash, feed on leftover body soil and produce a sour compound as the clothes dry. Wash with a full dose of detergent, as hot as the label allows, remove the load immediately and dry it fast.

How do you get the damp smell out of clothes?

The answer to how to get damp smell out of clothes is the rescue wash: soak them in oxygen bleach, wash hot within the care label limits with a full detergent dose, add white vinegar to the rinse, skip softener and dry quickly in moving air or a dryer. If the smell returns when the fabric warms up, repeat the soak and wash.

Does vinegar get rid of musty smells in clothes?

It helps. White vinegar in the rinse dissolves detergent and mineral residue that holds odour, and an hour-long vinegar soak before washing helps with mild mustiness. It is not a substitute for detergent and fast drying, and it should never be mixed with chlorine bleach.

How do you get a musty smell out of clothes without washing them?

Air them outdoors on a dry, breezy day, steam them and dry them fully, or mist the lining lightly with plain alcohol and air it. A sealed bag with an open dish of baking soda absorbs some odour. For tailoring, wool and leather, professional cleaning is the safest option.

How do you dry clothes indoors without them smelling?

Spin them hard, space them on a rack, point a fan at them and run a dehumidifier in the same room. Keep indoor humidity below 60%, as the US Environmental Protection Agency advises, and aim to have clothes dry the same day.

Can you spray perfume on musty clothes?

You can, but it backfires. Perfume does not kill odour-causing bacteria, and the two smells combine into something staler. Clean the clothes first, then apply fragrance to skin. A clean musk or fresh floral will then read as fresh laundry rather than a cover-up.

How long does it take for wet clothes to smell?

In warm, humid weather, a few hours can be enough for a sour note to start, and overnight in a closed bag or a washing machine almost guarantees it. Cooler, drier air buys more time, which is why the same habits smell worse in a monsoon than in a dry winter.

Your next rainy week

Pick one smelly item tonight and give it the full rescue wash: soak, hot wash, vinegar rinse, fast dry. Clean the machine seal while it runs. Tomorrow, pack a waterproof liner and a hanger for your rain gear. Most people only need to fix the drying habit once to stop the musty smell for good.

If you ride in Pune, check your route for flooded potholes before the next downpour. And once your clothes smell of nothing at all, find a clean scent you love for your skin: there are plenty more guides on the Fragranxe blog.
