Does your naked pillow bear a couple stains? Perhaps even a yellowish ring or two? Yeah, it’s time for a pillow bath. With all the sweat, drool, and bacteria that can be harbored in your cushion, it’s relieving to know that you could keep it fresh with a laundry cycle. Pillow cleaning is a task that is often overlooked, and should be done at least twice a year to remove mold and odors.
