Computers and other electronics comprise a good portion of our office configurations, and since they are used so frequently, often become the dirtiest items in the room. Wipe computer screens gently with a soft microfiber cloth. Blow computer keyboards out with compressed air. Next, clean the entire keyboard by dipping cotton swabs into rubbing alcohol and detailing on and around all of the keys. This process will clean and disinfect the keyboard, and help to halt the spread of germs. Dust the tops of printers and computer towers, fax machines and telephones with microfiber cloths and detail any parts with the cotton swab and alcohol that don't come into direct contact with the electric components.
