How to dry clothes indoors without the musty smell

Quick answer

That musty smell comes from clothes that take too long to dry. Use a high spin, get the wash out of the machine as soon as it finishes and hang it straight away with space between items. Put the airer where air moves, near an open window, and use a dehumidifier or fan on damp days. Avoid drying in a closed bedroom.

Musty-smelling laundry is laundry that took too long to dry, so the fix is speed. Use the highest spin your clothes can take, get the wash out of the machine as soon as it’s done, hang it immediately with gaps between items, and put the airer where the air actually moves, ideally near an open window. On damp days a dehumidifier or a fan makes a huge difference. A packed airer in a closed bedroom is where the smell comes from.

Why indoor-dried clothes smell

That “left in the machine” smell turns up when fabric stays damp for hours without airflow. The usual suspects:

  • Wet laundry left sitting in the drum after the cycle ends.
  • Not enough spin, so clothes come out dripping.
  • An overcrowded airer, with items touching each other.
  • A closed or humid room, like a windowless bathroom or a bedroom with the windows shut.
  • Too much detergent or softener, which stays in the fabric and holds on to smells.
  • A grubby machine, with gunk in the door seal or the detergent drawer.

There’s a knock-on effect for your home too. UK government guidance on damp and mould lists drying laundry, showering and cooking as everyday sources of moisture that build up indoors when they can’t escape, turning into condensation on cold walls and windows. That’s why ventilating matters as much as drying.

Step by step: drying faster

  1. Spin it hard. Pick the highest spin the care label allows, or run an extra spin. Every drop that leaves in the drum is one less on the airer.
  2. Get it out straight away. Use the delay timer so the wash finishes when you’re home.
  3. Shake each item before you hang it. It opens up the fabric and cuts down on creases.
  4. Leave gaps. Rule of thumb: if items are touching, the airer is full.
  5. Heavy on the outside, light in the middle. Towels, jeans and hoodies go where the air hits them; T-shirts and underwear in the middle.
  6. Use hangers for shirts, tops and dresses. They dry faster and come off nearly crease-free.
  7. Flip halfway. Jeans and towels dry slower on the inside.
  8. Bring it in once it’s dry. Dry clothes left on an indoor airer soak up moisture from the air again.

Where to put the airer

Spot Does it work? Tip
Room with an open window Best indoor option Crack the window, even in winter
Balcony Great when it’s dry out Shade for darks, which fade in strong sun
Living room near a window Good Window open, fan on if you have one
Near a radiator Fast Airer next to it, not wet clothes on top of it, and ventilate
Bedroom Only with the window open Avoid sleeping with a full airer in a closed room
Windowless bathroom Poor It’s already the dampest room you have

Cross-ventilation works wonders: open windows on two sides of the flat and air flows through. A fan pointed at the airer speeds things up even on rainy days, as long as the damp air has somewhere to go afterwards.

Damp days, damp flats and tumble dryers

When the air outside is damp too, an open window helps less. Options for those days:

  • A dehumidifier next to the airer, with the door shut. It pulls water out of the air and clothes dry much faster.
  • A heated airer, which is gentler on clothes and walls than draping things over radiators.
  • A fan blowing straight at the laundry.
  • Smaller loads. In a rainy week, wash what you need and save the rest for a drier spell.
  • A tumble dryer or washer-dryer, if you have one. The U.S. Fire Administration advises cleaning the lint filter before and after every load and keeping the vent clear, because lint build-up is a fire risk.

Keep an eye on walls, window frames and ceiling corners. If mould starts appearing, that’s your cue to ventilate more and dry less indoors. The same UK guidance notes that damp and mould hit some people harder, including children, older people, pregnant women and anyone with asthma or other breathing conditions. If someone at home has asthma or allergies that flare up with mould, it’s worth talking to a doctor, and if you rent, telling your landlord.

Keeping the smell from coming back

  • Clean the machine now and then: the door seal, the detergent drawer and a hot maintenance wash, as the manual suggests.
  • Leave the door ajar after each wash so the drum dries out.
  • Measure the detergent. More soap doesn’t mean cleaner clothes; it means residue.
  • Only put clothes away fully dry, seams and pockets included.

In a small flat, your laundry routine needs to fit your drying space. The laundry routine guide helps you pick a rhythm, and how to sort laundry saves you from rewashing. To make the rest of a small home work, see how to keep a small apartment organized.

Frequently asked questions

Is it OK to dry clothes on the radiator?

It's quick, but it pumps a lot of moisture into the room, and heavy wet items stop the radiator heating the room properly. A heated airer or a regular airer near a radiator, with the window cracked open, is a better bet.

My clothes dried but still smell. Can I fix them?

Yes: rewash with the right amount of detergent, then dry them faster this time, with more space and more airflow. Fabric softener won't remove a damp smell, it just covers it.

Is a tumble dryer worth it in a flat?

It helps a lot if space is tight or the climate is damp, but it needs room, proper venting or a condenser model, and it uses energy. A washer-dryer is an option if there's only space for one machine.

Jeans and towels take forever. Any tricks?

An extra spin, hang them fully open (jeans upside down by the waistband, inside out; towels folded over the line only once) and flip them halfway through. Give them the spot nearest the window.
