  • Diluted household bleach solutions may also be used if appropriate for the surface. Check to ensure the product is not past its expiration date. Unexpired household bleach will be effective against coronaviruses when properly diluted.

For electronics, such as tablets, touch screens, keyboards, remote controls, and ATM machines

  • Consider putting a wipeable cover on electronics.
  • Follow manufacturer’s instruction for cleaning and dinfecting.
  • If no guidance, use alcohol-based wipes or sprays containing at least 70% alcohol. Dry surface thoroughly.

  • Do not shake dirty laundry.

  • Remove gloves, and wash hands right away.

Cleaning and disinfecting your building or facility if someone is sick

  • Close off areas used by the person who is sick.
  • Open outside doors and windows to increase air circulation in the area. Wait 24 hours before you clean or disinfect. If 24 hours is not feasible, wait as long as possible.
  • Clean and disinfect all areas used by the person who is sick, such as offices, bathrooms, common areas, shared electronic equipment like tablets, touch screens, keyboards, remote controls, and ATM machines.
  • If more than 7 days since the person who is sick visited or used the facility, additional cleaning and disinfection is not necessary.
  • Continue routing cleaning and disinfection.

When Cleaning

  • Wear disposable gloves and gowns for all tasks in the cleaning process, including handling trash.
  • Additional personal protective equipment (PPE) might be required based on the cleaning/disinfectant products being used and whether there is a risk of splash.
  • Gloves and gowns should be removed carefully to avoid contamination of the wearer and the surrounding area.
  • Wash your hands often with soap and water for 20 seconds.
  • Always wash immediately after removing gloves and after contact with a person who is sick.
  • Hand sanitizer: If soap and water are not available and hands are not visibly dirty, an alcohol-based hand sanitizer that contains at least 60% alcohol may be used. However, if hands are visibly dirty, always wash hands with soap and water.

Additional key times to wash hands include:

  • After blowing one’s nose, coughing, or sneezing.
  • After using the restroom.
  • Before eating or preparing food.
  • After contact with animals or pets.
  • Before and after providing routine care for another person who needs assistance (e.g., a child).

Additional Considerations for Employers

  • Educate workers performing cleaning, laundry, and trash pick-up to recognize the symptoms of COVID-19.
  • Provide instructions on what to do if they develop symptoms within 14 daysafter their last possible exposure to the virus.
  • Develop policies for worker protection and provide training to all cleaning staff on site prior to providing cleaning tasks.
  • Training should include when to use PPE, what PPE is necessary, how to properly don (put on), use, and doff (take off) PPE, and how to properly dispose of PPE.
