How to Clean a Cloth Mask

Masks are way to help slow the spread of COVID-19 when combined with every day preventive actions and social distancing in public settings. Masks should be washed regularly. Also note that it is important to always remove masks correctly (handle by the ear loops or ties) and wash hands after touching a used mask.


Washing machine

  • You can include your mask with your normal laundry. Use regular laundry detergent and the warmest appropriate water setting for the cloth used to make the mask.

Washing by hand

  • Check the label to see if your bleach is intended for disinfection. Some bleach products, such as those designed for safe use on colored clothing, may not be suitable for disinfection.
  • Use bleach containing 5.25%-8.25% sodium hypochlorite. Do not use a bleach product if the percentage is not specified.
  • Ensure the bleach product is not past its expiration date.
  • Never mix household bleach with ammonia or any other cleanser and ensure adequate ventilation when using
  • Prepare a bleach solution by mixing five tablespoons of 5.25%-8.25% bleach per gallon of room-temperature water or four teaspoons of 5.25%-8.25% bleach per quart of room temperature water.
  • Soak the mask in the bleach solution for five minutes.
  • Discard the bleach solution down the drain and rinse the mask thoroughly with cool or room-temperature water.


Use the highest heat setting in the dryer and leave in the dryer until completely dry. Or, air-dry by laying the mask flat and allow to completely dry. If possible, place the mask in direct sunlight.
