Clean and Disinfect Against Coronavirus Disease COVID-19

Current evidence suggests the novel coronavirus (COVID-19) may be viable for hours or even days on surfaces depending on the materials. Cleaning of visibly dirty surfaces followed by disinfection is a “best practice” for prevention of COVID-19 and other viral respiratory illnesses in households and community settings.

Let’s start with a few definitions:

  • Cleaning refers to the removal of germs, dirt, and impurities from surfaces. Cleaning does not kill germs, but by removing them, it lowers their numbers and the risk of spreading infection.
  • Disinfecting refers to using chemicals to kill germs on surfaces. This process does not necessarily clean dirty surfaces or remove germs, but by killing germs on a surface after cleaning, it can further lower the risk of spreading infection.

How to clean and disinfect:

Surfaces

  • Wear disposable gloves when cleaning and disinfecting surfaces. Gloves should be discarded after each cleaning. If reusable gloves are used, those gloves should be dedicated for cleaning and disinfection of surfaces for COVID-19 and should not be used for other purposes. Consult the manufacturer’s instructions for cleaning and disinfection products used. Clean hands immediately after gloves are removed.
  • If surfaces are dirty, they should be cleaned using a detergent or soap and water prior to disinfection.
  • 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. 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
    • Products with EPA-approved emerging viral pathogens claims are expected to be effective against COVID-19 based on data for harder to kill viruses. Follow the manufacturer’s instructions for all cleaning and disinfection products.
  • For soft (porous) surfaces such as carpeted floor, rugs, and drapes, remove visible contamination if present and clean with appropriate cleaners indicated for use on these surfaces. After cleaning:
    • Launder items as appropriate in accordance with the manufacturer’s instructions. If possible, launder items using the warmest appropriate water setting for the items and dry items completely, or
    • Use products with the EPA-approved emerging viral pathogens claims suitable for porous surfaces.

Clothing, towels, linens, and other items that go in the laundry

  • Wear disposable gloves when handling dirty laundry from an ill person and then discard after each use. If using reusable gloves, those gloves should be dedicated for cleaning and disinfection of surfaces for COVID-19 and should not be used for other household purposes. Clean hands immediately after gloves are removed.
    • If no gloves are used when handling dirty laundry, be sure to wash hands afterwards.
    • If possible, do not shake dirty laundry. This will minimize the possibility of dispersing virus through the air.
    • Launder items as appropriate in accordance with the manufacturer’s instructions. If possible, launder items using the warmest appropriate water setting for the items and dry items completely. Dirty laundry from an ill person can be washed with other people’s items.
    • Clean and disinfect clothes hampers according to guidance above for surfaces.
