Computer Hygiene

Cleaning Your COmputer

First, remove any media from the drives and turn off all connected devices and the computer. Then, disconnect all power sources such as batteries or power cords from electrical outlets and disconnect all cables that are connected to the computer.


Use only mild cleaning solutions (non-ammonia based and non-abrasive) and a damp lint-free, soft cloth to clean the painted surfaces of the computer.

  • Apply non-ammonia based cleaner onto the cloth.
  • Absorb the cleaner into a sponge or lint-free, soft cloth.
  • Squeeze out the excess liquid from the sponge or cloth.
  • Wipe the cover using a circular motion taking care not to let any excess liquid drip.
  • Wipe the surface to remove any left-over cleaner.
  • Rinse the sponge or cloth with clean running water and squeeze out any excess liquid.
  • Wipe the cover with the clean sponge or lint-free, soft cloth.
  • Wipe the surface again with a dry, lint-free, soft cloth.
  • Wait for the surface to dry completely and then remove any fibers left from the sponge or cloth.


  • Absorb some isopropyl alcohol on a lint-free, soft cloth.
  • Squeeze out excess liquid from the lint-free, soft cloth.
  • Wipe the keytop surface with the lint-free, soft cloth, ensuring no liquid drips on or between the keys.
  • Allow to dry.


  • Gently wipe the display with a dry, lint-free, soft cloth.
  • Wipe or dust the stain gently with a dry, soft cloth.
  • If a stain, smudge, or other blemish remains, moisten a lint-free, soft cloth with water or a 50-50 mixture of isopropyl alcohol and water (distilled or deionized).
  • Wring out as much of the liquid as you can from the lint-free, soft cloth.
  • Wipe the display again; do not let any liquid drip into the computer.
  • Allow the display to dry, then close the lid if the computer has one.


  • Anti-static LCD cleaning cloths, Kim Wipes, and some types of lens cleaning wipes are also acceptable alternatives for a lint-free, soft cloth.
  • Isopropyl alcohol is a flammable liquid. Do not use this cleaner near an exposed flame or when the system is on.
  • Never spray or pour any liquid cleaner directly on the LCD display or the keyboard.

Disinfecting your computer

Medical wipes and their chemical composition vary greatly. Depending on the chemicals, frequency, and duration of use, medical wipes may impact cosmetic appearance and system functionality. To minimize this risk, we recommend:

  • Hydrogen peroxide wipes (such as Virox Accel wipes with a maximum of 0.5% hydrogen peroxide)
  • Alcohol-based wipes (such as PDI Germicidal or B.Braun Meliseptol Wipes sensitive)
  • Do not use wipes containing sodium hypochlorite (bleach).
  • Wiping away residual solvent as soon as possible after the prescribed contact time and wiping the surface again with a dry, lint-free, soft cloth.

It is safe to use a disinfecting wipe designed for office/home use. Some disinfecting wipes designed for medical use may cause discoloration, harm surfaces, or even affect functionality of your device. To minimize symptoms, we recommend the following:

  • Squeeze out excess liquid from wipe or disinfecting cloth before using.
  • Gently wipe the system thoroughly, being careful to ensure no liquid drips into the computer. Do not wipe on connector pins.
  • After disinfecting, follow the cleaning procedure from the wipe supplier to minimize chemical buildup of disinfectant residue (i.e. wiping away any residual disinfectant after the prescribed contact time).
  • Always allow the computer to completely dry prior to any use.
