A travel neck pillow needs to be cleaned regularly by hand-washing it using a mild detergent and lukewarm water. After washing, it should be hung up to dry in a cool and well-ventilated area. Avoid direct heat and sunlight when drying the pillow. To prevent the filling from shifting, it is recommended to shake the pillow after it has been dried. Additionally, it is important to inspect the pillow for any signs of wear and tear and to replace it if necessary.
