We recommend that you wash your mask before your first use, and after each wear.
Your cloth mask should be machine-washed with COLD WATER ONLY as 100% cotton masks may shrink when washed with warm or hot water. Temperature does not matter when disinfecting your mask in the wash as long as your mask is washed with soap.
Tumble dry on low or hang mask to dry after washing. Ensure the mask is completely dry before storing and store in a clean bag or container between uses.
