CDC GGuide on how to clean and disinfect a household

Purpose

This guidance provides recommendations on the cleaning and disinfection of households where persons under investigation (PUI) or those with confirmed COVID-19 reside or may be in self- isolation. It is aimed at limiting the survival of the virus in the environments. These recommendations will be updated if additional information becomes available.

These guidelines are focused on household settings and are meant for the general public.

  • Cleaning refers to the removal of germs, dirt, and impurities from surfaces. It does not kill germs, but by removing them, it lowers their numbers and the risk of spreading infection.
  • Disinfecting refers to using chemicals, for example, EPA-registered disinfectants, 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.

Hard (Non-porous) 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, most common EPA-registered household disinfectants should be effective.
    • A list of products that are EPA-approved for use against the virus that causes COVID-19 is available hereexternal icon. Follow manufacturer’s instructions for all cleaning and disinfection products for (concentration, application method and contact time, etc.)

Always read and follow the directions on the label to ensure safe and effective use.

  • Wear skin protection and consider eye protection for potential splash hazards
  • Ensure adequate ventilation
  • Use no more than the amount recommended on the label
  • Use water at room temperature for dilution (unless stated otherwise on the label)
  • Avoid mixing chemical products
  • Label diluted cleaning solutions
  • Store and use chemicals out of the reach of children and pets

You should never eat, drink, breathe or inject these products into your body or apply directly to your skin as they can cause serious harm. Do not wipe or bathe pets with these products or any other products that are not approved for animal use.

Special considerations should be made for people with asthma and they should not be present when cleaning and disinfecting is happening as this can trigger asthma exacerbations. To learn more about reducing asthma triggers: https://www.cdc.gov/asthma/reduce_triggers.html

    • Additionally, diluted household bleach solutions (at least 1000ppm sodium hypochlorite, or concentration of 5%–6%) can be used if appropriate for the surface. Follow manufacturer’s instructions for application, ensuring a contact time of at least 1 minute, and allowing proper ventilation during and after application. 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 room temperature water or
    • 4 teaspoons bleach per quart of room temperature water
  • Bleach solutions will be effective for disinfection up to 24 hours.

Soft (Porous) Surfaces

  • 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:

Electronics

  • For electronics such as cell phones, tablets, touch screens, remote controls, and keyboards, remove visible contamination if present.
    • Follow the manufacturer’s instructions for all cleaning and disinfection products.
    • Consider use of wipeable covers for electronics.
    • If no manufacturer guidance is available, consider the use of alcohol-based wipes or sprays containing at least 70% alcohol to disinfect touch screens. Dry surfaces thoroughly to avoid pooling of liquids.

Linens, clothing, 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. If possible, consider placing a bag liner that is either disposable (can be thrown away) or can be laundered.
