Preventing Mould When Drying Laundry Indoors – Tips & Measures

Drying clothes indoors requires a few essential strategies to avoid mould growth and excessive humidity. Here are the most important tips:

Create optimal conditions

• Choose a warm room with a temperature around 20°C to prevent mould development.
• Place the drying rack with the top end near an open window to improve air circulation and reduce moisture.
• Avoid direct sunlight, as it can cause discoloration and damage sensitive materials.

Dry clothes efficiently

• Use the highest spin cycle when washing to minimise residual moisture. Less moisture means lower risk of mould growth.
• Hang garments with enough space between them to allow airflow and reduce the chance of moisture and mould buildup.
• Use hangers for some items to save space and speed up drying time.

Ventilation and room climate

• Ventilate several times a day for about 10 minutes, ideally with a draft, to reduce excess moisture and the risk of mould.
• Open two opposite windows to increase airflow. This promotes a drier indoor climate that prevents mould formation.
• Lower the heating during ventilation to save energy.

Additional measures

• Use a dehumidifier to keep humidity levels low and reduce the risk of mould infestation.
• Consider using a fan to support drying and distribute moisture more evenly.
• For delicate items, use the “towel trick”: roll the garment in a towel and gently press to absorb excess moisture.

If you notice mould in your home despite these precautions, consider conducting a mould test or a professional mould analysis to identify the cause. This can help determine the mould type and the right countermeasures.

Note: drying laundry indoors is generally permitted, even if the rental agreement claims otherwise. If problems with high humidity or visible mould persist, contact your landlord to find a solution together.
