Disinfection procedures for departments and electronics

The current health status has magnified the importance of cleaning and disinfection.  WSU’s custodial staff is focusing on high use areas and touchpoints.  This leaves some areas with minimal custodial services.  In these areas departments can take a few steps – including minimizing food in work spaces as much possible – to reduce potential exposure:

  1. Select a ready to use disinfectant, not a concentrated product that must be diluted with water.
    1. In Pullman: Ready to use Clorox, Lysol or 409 are effective examples, University Stores has products available to Departments.
    2. Other locations:  Departments would need to buy disinfection supplies from a non-university location.
  2. If disinfectants are not available use soapy water.  SARS-CoV-2 is an enveloped virus that is inactivated by soap and water and most disinfectants.
  3. Turn off all electronic devices.
  4. Clean dusty and dirty surfaces by wiping with soapy water.  Dirt and dust prevent disinfection.
  5. Spray (not stream) disinfectant onto all common touched surfaces such as desk tops, door knobs, file cabinets, chairs, etc.  If using bleach understand that cloth and other absorbent material may be damaged.
  6. If disinfecting electronics, dampen a paper towel with disinfectant and wipe down.  Disinfectant should not be dripping off paper towel, but wet enough to ensure disinfectant is present.
  7. Focus on keyboards, mice, and telephones, include the sides and bottom.
  8. Allow all surfaces to dry on their own.  Disinfectants must be allowed to act on the surface to be effective, wait 15 minutes.
  9. Remember to wash your hands with soap when you have finished.

One area of concern is electronics, specifically keyboards, mice, and telephones.  Disinfection is a little more complicate because disinfectant is most effectively applied in the liquid form which does not seem appropriate for electronics.  In these areas individuals should follow these steps before use and after use:

  1. Select a ready to use disinfectant, not a concentrated product that must be diluted with water.
    • In Pullman: Ready to use Clorox, Lysol or 409 are effective examples, University Stores has products available to departments.
    • Other locations:  Departments would need to buy disinfection supplies from a non-university location.
  2. If disinfectants are not available use soapy water.  SARS-CoV-2 is an enveloped virus that is inactivated by soap and water and most disinfectants.
  3. Although a disinfectant wipe is preferred, these items are not readily available.  Instead dampen a paper towel with disinfectant.  Disinfectant should not be dripping off paper towel, but wet enough to ensure disinfectant is present.
  4. Do not use aerosolized air to blow dust off of electronics.
  5. Wipe down all electronics with saturated paper towel.  Be sure to get all sides of a mouse and keyboard.  Throw paper towel in the garbage.
  6. Allow the surface to dry on their own.  Disinfectants must be allowed to act on the surface to be effective.  This should take only a few minutes.
  7. While waiting throw paper towel in the garbage and wash your hands with soap.
