Guidance for Cleaning and Disinfecting

To ensure the cleanliness of our own spaces and to minimize the possibility of exposure to infectious agents, we encourage you to use disinfectant (provided by Facilities) to clean and disinfect your immediate area before, during and after use, and as often as you deem necessary.   

  • Facilities will perform cleaning and disinfecting of public spaces, workplaces, classrooms and other facilities, as needed

  • Building systems will be closely monitored.  Domestic water lines will be adequately flushed before buildings are opened; air filters in HVAC systems will be replaced

  • General services in office and other spaces will continue as before.  Additional cleaning and increased frequencies will be needed in high-traffic and common spaces.  A special cleaning team will be assembled for cleaning when a confirmed case has been determined.

  • Employees and students will sanitize their own spaces in between regularly scheduled cleanings. Supplies, including an informational fact sheet on the proper use of the cleaner, will be available at various locations.

 Guidance for cleaning and disinfecting

Follow These Safety Precautions

  • Keep this cleaner in the designated spray bottle with the appropriate label.  DO NOT remove the label or transfer the cleaner to another unlabeled container.
  • For additional bottles or to obtain a refill contact the Facilities Services front office at extension 4286, or at
    Because of the limited supply of disinfectants, a single spray bottle is appropriate for a department office space, a lunchroom, a foyer, a classroom, a residential suite, restroom, or similar occupied space.
  • Read the label if you have any concerns regarding the use of this disinfectant.  
  • Store and use this disinfectant in a responsible and appropriate manner according to the label. 
  • Do not mix bleach or other cleaning and disinfection products with this cleaner.  
  • This cleaner is similar to traditional household cleaners and is safe to use without personal protective equipment (PPE) if common sense and general use precautions are followed.
  • This product is intended for hard, nonporous inanimate surfaces; do not spray on skin or fabrics.
  • When using this product, do not eat, drink, or smoke, and wash your hands after use.
  • Additional information about this disinfectant and the Safety Data Sheet can be obtained from the Health & Safety office at extension 8287 or at

Disinfectant Application Guidelines

This product is intended for cleaning and disinfecting high-touch areas including your workplace, office, desktop, keyboard, mouse, doorknobs, light switches, refrigerator handles, exterior of microwave ovens, dining tables, phones, and other frequently touched surfaces. This product is safe to use without gloves if common sense and general use precautions are followed.

  • Spray a small amount on a paper towel and wipe the area until it is wet.  Wipe down with a clean cloth or paper towel, or allow to dry.
  • Wash your hands after use, discard the paper towel in the green bin (compost) and return the spray bottle to its storage location.
  • Do not spray directly on and into keyboards, mice or other sensitive electronics.   Instead, wipe the surfaces with a dampened paper towel.

Important Reminders about Coronavirus and Reducing the Risk of Exposure

  • Coronaviruses on surfaces and objects naturally die within hours to days. Warmer temperatures and exposure to sunlight will reduce the time the virus survives on surfaces and objects.
  • Normal routine cleaning with soap and water removes germs and dirt from surfaces. It lowers the risk of spreading COVID-19 infection.
  • Disinfectants kill germs on surfaces. By killing germs on a surface after cleaning, you can further lower the risk of spreading infection.  Disinfectants are an important part of reducing the risk of exposure to COVID-19.
  • Store and use disinfectants in a responsible and appropriate manner according to the label. Do not mix bleach or other cleaning and disinfection products together--this can cause fumes that may be very dangerous to breathe in. Keep all disinfectants out of the reach of children.
  • Do not overuse or stockpile disinfectants or other supplies. This can result in shortages of appropriate products for others to use in critical situations.
  • Practice social distancing, wear facial coverings, and follow proper prevention hygiene, such as washing your hands frequently and using hand sanitizer when soap and water are not available.

How to Determine What Needs to be Cleaned

Some surfaces only need to be cleaned with soap and water. For example, surfaces and objects that are not frequently touched should be cleaned and do not require additional disinfection. 

If the Area is Outdoors

Outdoor areas generally require normal routine cleaning and do not require disinfection. Spraying disinfectant on sidewalks and in parks is not an efficient use of disinfectant supplies and has not been proven to reduce the risk of COVID-19 to the public. You should maintain existing cleaning and hygiene practices for outdoor areas.  The targeted use of disinfectants can be done effectively, efficiently and safely on outdoor hard surfaces and objects frequently touched by multiple people.

If the Area has Been Unoccupied for the Last 7 days

If your workplace or building has been unoccupied for 7 days or more, it will only need your normal routine cleaning to reopen the area. This is because the virus that causes COVID-19 has not been shown to survive on surfaces longer than this time.


How to Determine What Needs Disinfecting

Only hard and non-porous material or items like glass, metal, or plastic should be disinfected.  Examples of frequently touched surfaces and objects that will need routine disinfection:

• Tables and chairs
• Doorknobs
• Light switches
• Countertops
• Handles
• Desks
• Keyboards
• Toilets
• Faucets and sinks
• Phones
• Touch screens

Each workspace, department or facility will have different surfaces and objects that are frequently touched by multiple people.  Be empowered to appropriately disinfect these surfaces and objects, as needed. Soft and porous materials are generally not as easy to disinfect as hard and non-porous surfaces. Soft and porous materials that are not frequently touched should only be cleaned or laundered.  In this case, please contact the Health & Safety department (link) to have our janitorial service clean or launder these items. 

Maintain safe behavioral practices

When the campus opens, we will need to continue these general practices:

  • Social distance, maintain a 6 foot distance from others whenever possible. 
  • Frequently wash hands and use hand sanitizer when soap and water are not available.
  • Wearing cloth face coverings both indoors and outdoors, unless you are actively eating or in your own bedroom.
  • Avoid touching eyes, nose, and mouth with unwashed hands.
  • Stay home when sick or not feeling well.
  • Clean and disinfect frequently touched objects and surfaces.

It’s important to continue to follow these guidelines for reopening the campus. Continuously check campus resources for updates on COVID-19.
