What are the guidelines for cleaning and reusing cloth face coverings used in public settings?

The CDC recommends washing cloth face coverings after each use. Cloth face coverings may be washed at the end of the day as long as the cloth face covering was removed and stored following ASU guidelines.

Cloth face coverings may be washed by hand or in a washing machine. Make sure to completely dry cloth face covering after washing. The CDC provides the instructions listed below.

Washing machine

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

Washing by hand

1. Prepare a bleach solution by mixing:
   1. 5 tablespoons (1/3 cup) household bleach per gallon of room-temperature water or
   2. 4 teaspoons household bleach per quart of room-temperature water
2. 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. Ensure the bleach product is not past its expiration date. Never mix household bleach with ammonia or any other cleanser.
3. Soak the face covering in the bleach solution for 5 minutes.
4. Rinse thoroughly with cool or room-temperature water.
5. Dry:
   1. Dryer: Use the highest heat setting and leave in the dryer until completely dry.
   2. Air dry: Lay flat and allow to completely dry. If possible, place the cloth face covering in direct sunlight.
