Drying laundry indoors is convenient because it is not affected by the weather and does not carry a theft risk, but the cause of unpleasant odors is bacterial growth. Once you understand the right countermeasures, the drawbacks of indoor drying can be resolved.

What are the benefits of drying laundry indoors?

  • Pollen, dust, and PM2.5 do not stick to your clothes:This is also helpful for people with respiratory conditions or hay fever
  • It is not affected by the weather:Even if it suddenly rains, there is no need to rush, which helps save time on household chores
  • It helps prevent theft:This is especially reassuring for women living alone

What causes indoor-drying odors?

Indoor-drying odor is caused by bacterial growth when laundry takes too long to dry. Because you cannot rely on outdoor air or sunlight, moisture tends to build up more easily.

How can you eliminate indoor-drying odors?

Hang laundry near a window

A sunny living-room window is the best spot. However, avoid hanging laundry from the curtain rail, and use a tension rod or similar item so that you can keep space between each piece.

Wash laundry frequently

If you leave laundry sitting in the washer, moisture encourages bacterial growth. It is important to use a breathable laundry basket and wash clothes regularly.

Clean the washing machine drum regularly

Keep the inside of the washing machine drum clean with an oxygen-based cleaner or baking soda. Leaving the lid open after use also helps prevent mold.

Use indoor-drying tools

If you use an air circulator, fan, or dehumidifier to direct airflow onto your laundry, the drying process starts faster right after washing and helps prevent odors from developing.

FAQ

Q. Are there detergents that help prevent odors when drying laundry indoors?

Using a detergent designed for indoor drying or an oxygen-based bleach together with your detergent can suppress bacterial growth and help prevent odors.

Q. Where is the best place to dry laundry indoors?

A window in the living room is the best option in terms of sunlight and ventilation. Using the bathroom exhaust fan is also effective.

Q. What should I do if my laundry will not dry indoors?

Try these three measures: direct airflow with an air circulator, use a dehumidifier at the same time, and leave wider gaps between items of laundry.
