Every time you wear a reusable cloth mask, it needs to be washed. After wearing for even a short amount of time, the fabric will absorb bacteria and contaminants from the air. Dermatologists are even treating cases of “maskne” where an unclean mask has rubbed the skin. Washing a mask is as easy as throwing it in with other laundry, drying at high heat or air drying in the sunshine. Stay safe and thanks for masking up.
