Your pillowcase harbors hidden grime: How often to wash it

Importance of a clean pillowcase

A pillowcase constantly comes into contact with sweat, hair, skin oils, dead skin flakes, dandruff, body dirt, and even saliva. Washing pillowcases frequently is important not only to protect hair and skin from excess dirt and bacteria but also to “protect” the pillow itself.

Dust particles, skin flakes, body dirt, and allergens can penetrate through the pillowcase and fabric cover into the pillow filling, reducing its resilience.

Additionally, dust mites can exacerbate allergies and asthma.

How often to wash

The frequency of washing a pillowcase can depend on factors such as sleeping with wet hair or using heavy skincare products at night.

In general, it is recommended to wash pillowcases at least once a week, but ideally twice.

Even washing your face before bed may not remove all dirt and makeup, which can leave stains on sheets and pillowcases that then come into contact with your skin again every night.

To make washing easier, it’s good to have two pillowcases for each pillow. That way, the dirty one can be quickly swapped midweek for a fresh one, and both can be washed together with the sheets at the end of the week.

Laundry tips

Following these tips can help optimize the washing process and keep pillowcases clean:

• Check the care label for instructions
• Wash cotton pillowcases in warm water with high-quality detergent
• If you have sensitive skin, choose a detergent without dyes or fragrances
• Wash silk pillowcases with a gentle detergent in cold water, as this material requires delicate care
• Air-dry pillowcases instead of using a dryer
• Avoid fabric softeners, as they can leave residues and reduce breathability
