How to Safely Clean a Laptop Screen

By Melissa Rae

Laptop screens tend to collect dirt, dust and smudges from everyday use. Laptop manufacturers advise against using regular window cleaner on your screen, because the ammonia and other chemicals can ruin the screen's finish. Safely clean your laptop screen with an LCD screen cleaner or a homemade solution of alcohol and distilled water.

Things You'll Need

  • Isopropyl alcohol
  • Distilled water
  • Spray bottle
  • LCD cleaner
  • Soft cloth, preferably microfiber

Step 1

Add 1 part isopropyl alcohol and 1 part distilled water to an empty spray bottle. Close the bottle and shake it to combine the ingredients.

Step 2

Turn off the laptop. It's easier to see the dust and smudges when the screen is dark.

Step 3

Spray a lint-free cloth with the homemade cleaning solution or LCD cleaner.

Step 4

Wipe the laptop screen thoroughly with the cloth to remove any dust or fingerprints. Clean in one direction to prevent streaks.

Tips & Warnings

  • Avoid spraying the cleaning solution directly onto the laptop screen to keep it from running down into the keyboard.
  • Always use distilled water instead of tap if you make your own cleaner. Tap water contains minerals that can discolor your laptop screen.
