When it's humid outside, even freshly washed laundry can suddenly feel heavy and musty. It feels like it hangs on the rack forever, towels stay damp, and the room is filled with that humid air that nobody wants. This isn't just unpleasant: if moisture remains in the apartment for too long, the risk of bad odors and mold spots increases.
The good news: You usually don't need a dryer. The key factors are spacing, air circulation, the right time for ventilation, and a washing machine that doesn't smell itself. Here are the simple steps that make the biggest difference in everyday life.
1. Take laundry out of the machine immediately
The most important step happens right after the wash cycle: Do not leave the laundry in the drum. Especially in summer, a few hours are enough for damp textiles to smell unpleasant. If it is foreseeable that no one will be home, it is better to postpone the start of the wash or use the timer so that the laundry is finished shortly before you return home.
After unloading, leave the door and detergent drawer open. This helps to remove residual moisture from the machine. If the machine itself smells musty, it is also worth taking a look at our tipHow to get rid of the annoying smell in the washing machine.
2. Spin better, but pay attention to the material
The wetter the laundry comes out of the machine, the longer it burdens the room air. Towels, bed linen, and robust cotton can therefore usually be spun more vigorously. Delicate clothing, wool, or fine fabrics naturally need the appropriate program according to the care label.
Anyone drying a lot of laundry in a small apartment should plan for two smaller wash loads rather than one overcrowded rack. That sounds slower, but often dries better in humid air because air can actually circulate between the items.
3. Leave space on the drying rack
A crowded drying rack is the most common mistake in humid weather. T-shirts and towels should not stick directly to each other. Large pieces like bed linen or bath towels dry faster if they are laid over two lines and not hung down as a thick block.
- Hang heavy towels on the outside where there is more air.
- Hang shirts and blouses on hangers so they dry more freely.
- Leave one line of space between items if the room is very humid.
- Do not collect wet bath towels in the laundry basket after swimming or showering.
If there is sunscreen on towels or shirts, pre-treatment is also useful. The guide fits thisRemoving sunscreen stains: What helps with clothing and towels.
4. Do not dry in a closed room
Laundry releases a lot of moisture into the room air while drying. In a small, closed room, the air quickly becomes heavy, and the laundry dries more slowly. A bright, well-ventilated room where the rack is not standing directly against a wall, cupboard, or curtain is better.
A hygrometer is practical for this and costs little. It shows whether the humidity rises significantly after hanging up the laundry. If the room becomes permanently damp, you should ventilate briefly and vigorously more often. Tilting windows for many hours often brings less benefit in humid outside air than a few minutes of cross-ventilation at the right time of day.
5. Use the right time for ventilation in summer
On hot, humid days, the outside air is not automatically helpful at noon. Laundry often dries better if you ventilate early in the morning, late in the evening, or after a change in weather. Short cross-ventilation is ideal: open windows wide, if possible on opposite sides, and then close them again so that warm humidity does not constantly enter.
If the apartment is prone to mold anyway, laundry should not be dried in a windowless bathroom or directly in front of cold outer walls. The article also fits for preventionHow to recognize mold in your home before it becomes visibleas well asHow to properly remove mold in the bathroom.
6. Move air instead of masking odors
A fan can help if it gently moves the air in the room. It does not dry through heat, but prevents a layer of humid air from remaining directly around the laundry. A safe location with distance from wet laundry and cables is important.
What helps less: more detergent, extra fabric softener, or laundry perfume. Too much detergent can leave residues, and fragrances usually only mask musty laundry for a short time. It is more sustainable to fix the cause: wash cleanly, hang up quickly, dry in an airy place.

7. When a dehumidifier makes sense
In some apartments, there is no balcony, no drying room, and little cross-ventilation. Anyone who regularly dries several loads there can save time with a dehumidifier. However, it should be used consciously: close the room, let the device run only during the most humid phase, and keep an eye on power consumption. For individual small loads, better spinning, more space, and targeted ventilation are often enough.
If the laundry already smells musty
If a piece of clothing still smells musty after drying, it does not belong in the closet. It is best to wash it again promptly and then hang it up in an airy place immediately. Especially with towels, sportswear, and bed linen, you will quickly notice the smell again later as soon as the fabric becomes warm or slightly damp.
My brief conclusion: In humid weather, it's not the hottest corner that wins, but the moving air. Less laundry per rack, short ventilation windows at the right time of day, and a clean machine usually solve the problem without additional fragrances.
