Most Mac computer screens are glass-coated and can be cleaned and left streak-free more easily than most LCD screen products just by using glass cleaners like Windex or a cloth lightly sprayed with a small amount of rubbing alcohol.

Cleaning Tips for Computer Screens


  • Always turn off and unplug your computer and monitor before cleaning.
  • Avoid using excess moisture, especially when cleaning around plugs and ports.
  • Use soft, lint-free microfiber cloths and nothing rough or abrasive like sponges.
  • Never spray any cleaner directly onto your screen! Spray it onto a cloth, and use the cloth to wipe down the screen.
  • Do not ever use bleach to clean any of your electronics!
  • Make sure you know the type of screen you have, and refer to any manufacturer guidelines for cleaning if you have any doubts.
  • Wipe down the surface of your keys and your mouse when you’re cleaning your screen since many germs are also on those surfaces.
  • Use a clean, dry microfiber cloth when it comes to removing dust so that you don’t risk scratching the screen.

Since your keyboard is the part of your laptop you’re touching most, you might be wondering if you should use disinfectants on this surface as well. Apple recommends using 70% isopropyl alcohol wipes or Clorox Disinfecting Wipes to gently wipe the surfaces like displays, keyboards, and exterior surfaces. Don’t be afraid to wipe down your keyboard with a wipe after you clean your laptop’s screen.




Despite recommendations, keyboards are made with plastic keys that are non-porous and will be okay if you’re careful in ensuring excess liquid isn’t seeping between and beneath the keys. For disinfecting and sanitizing tips, check out what the CDC has to say. Just like when you clean your screen, you’ll want to make sure your computer or keyboard is off. You can hold your laptop at a 75° angle and use a can of compressed air to blow away any loose debris that’s become lodged between keys before wiping it down. Using a clean microfiber cloth or cotton swab dipped in rubbing alcohol is recommended by HP,  go over each of the keys to clean and sanitize them.


There are different types of screens, and your cleaning options will vary based on the surface. If you do it wrong, the cleaning agents could affect the display of sensitive crystals or cause permanent streaks and scratches. Always follow the manufacturer’s cleaning advice, especially if your device is still under warranty. Cleaning your laptop screen usually comes down to whether or not it has a glass covering. For Macs, this is usually the case, but PC models may not have glass over their LCD screens. When in doubt, refer to your user’s manual, or reach out to your laptop’s manufacturer online via email or on-site support chats to learn more.
