Hand Washing Techniques for Delicate Materials

When machine washing isn’t suitable for your pillow’s delicate materials, hand washing becomes the safest cleaning method.

To air dry properly, place the pillow in a well-ventilated area where you can maintain shape while avoiding direct sunlight that degrades delicate materials.

Pillow Lifespan and Replacement Guidelines

While proper maintenance and odor removal techniques can greatly extend your pillows’ usability, they won’t last forever regardless of how well you care for them.
