Face masks should be cared for with vigilance and consistency. The CDC recommends that a face mask be washed or sanitized after every use. Frequent washing may wear out the elastic or fibers; therefore, certain precautions should be taken. When machine washing, it is best to use mild detergent and cold to warm water. Avoid intense chemical soaps, extreme heat, and twisting or stressing the fabric. Depending on the materials used, hand-washing may be recommended. For example, silk or jacquard masks or embellished masks will require hand-washing because of the delicate fibers used. We recommend that you hang your masks up to dry, rather than using a dryer. Proper mask care is crucial to prevent contamination from any particles that may exist on the outside of the mask.
