The following is from the CDC (Center for Disease Control) about how to use bleach to clean Coronavirus Disease 2019 (COVID-19).
Diluted household bleach solutions can be used if appropriate for the surface. Follow manufacturer’s instructions for application and proper ventilation. Check to ensure the product is not past its expiration date. Never mix household bleach with ammonia or any other cleanser. Unexpired household bleach will be effective against coronaviruses when properly diluted.
Prepare a bleach solution by mixing:
- 5 tablespoons (1/3rd cup) bleach per gallon of water or
- 4 teaspoons bleach per quart of water
