When to air instead

Short answer: Air clothes when they only smell slightly and have no visible stains. Airing works for outer layers and for clothes worn for a single day, but never for anything that has become damp with sweat. That needs a wash.

Light odours disappear in dry air

Most odours evaporate overnight on a hanger. That takes dry air and a little space around the fabric so air can reach it from all sides. An open window or a hook in the hallway often works better than a full wardrobe. By morning, an outer layer usually feels fresh again, and you have saved a wash.

What can be aired

Airing works best for outer layers and clothes worn for just one day. Sweatshirts, cardigans, trousers and a long-sleeve bamboo T-shirt worn over another layer can often be aired and worn again. What sits directly against the skin all day is different. Underwear and socks need washing after every wear, however they smell.

Stains need a wash

A stain does not disappear on its own and sets over time. Airing removes odour, but not what sits in the fibres. Treat the stain as soon as you can and wash the item before it has time to set. The longer a stain stays, the harder it is to get out.

Sweat-soaked clothes must be washed

Once fabric has been wet, salt and sweat sit in the fibres. Airing does not remove them, even if the smell eases a little. Gym clothes, clothes from a hot day and anything that has been damp belong in the wash. Let them dry before they go in the basket, so the smell does not spread.

How to air properly

Hang the clothes on a hanger and give them space. An item squeezed between others does not get enough air. Turn it inside out so the side that was against the body gets the most air. Eight to twelve hours in dry air is usually enough. Avoid damp rooms such as the bathroom.

Underwear and socks always need washing

Some things can never be aired clean. Bamboo boxers and bamboo socks for men and women sit close to the skin all day and pick up sweat and skin oils, even when they do not smell. They need washing after every wear. Airing is for outer layers, not for what sits underneath.

Airing is gentler on clothes

Every wash wears fabric and elastic a little. When an outer layer can be aired instead of washed, it lasts longer and keeps its shape better. It also saves time, water and electricity. Airing is not a last resort but a good habit for the pieces that do not sit against the skin all day.

A simple rule of thumb

Ask yourself three things before something goes in the basket. Does it only smell slightly? Are there no stains? Is it dry? If the answer is yes to all three, it can be aired. If any answer is no, wash it. That rule makes the decision easy, even in the evening with the clothes in your hand.

Frequently asked questions

When is airing enough

When the clothes only smell slightly and have no stains. One night on a hanger in dry air is enough for an outer layer to feel fresh again.

When is airing not enough

With stains and with clothes that have become damp with sweat. Both sit in the fibres and only a wash removes them, however long they hang.

How long does airing take

One night. Eight to twelve hours in dry air with space around the fabric removes most light odours from an outer layer.
