How to clean your computer/phone/tablet without damaging it


  • Shut off the device and unplug it from the power adapter before cleaning
  • Use a soft, lint-free cloth
  • Spray cleaning product on cloth until slightly damp (1-2 sprays)

Recommended Products:

  • Microfiber cloth (or a cloth as gentle as one you would use to clean eyewear) to avoid scratching the screen
  • Non-ammonia based glass cleaner or isopropyl alcohol to avoid warping the screen
  • Multipurpose cleaner in a spray bottle or Clorox wipes for areas other than the screen


  • Spray cleaning product directly onto the computer
  • Put too much pressure on the screen or keys
  • Expose the device to excessive moisture
  • Use products that contain ammonia on the screen

Products to avoid:

  • Most Windex products, acetone, ethyl alcohol, or Clorox wipes for the screen
  • Paper towels, toilet paper, tissue paper, and non-cotton fabric
  • Water
