According to the CDC, you can make a DIY cleaning spray by mixing 4 teaspoons bleach per quart of water.
For disinfection, diluted household bleach solutions, alcohol solutions with at least 70% alcohol, and most common EPA-registered household disinfectants should be effective.
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
