The “L” in LCD stands for “liquid,” and what holds this liquid in is not a glass plate like you remember having on your big, heavy CRT or television. It’s soft plastic, and you’ve got to treat it very delicately.
So, first of all, let’s decide what we don’t use to clean it:
- Anything containing bleach or ammonia, such as Windex. That will react with the plastic and make the plastic screen become cloudy and discolored.
- Anything sharp, pointy or abrasive.
Your easiest choice is one of those LCD cleaning solutions they sell in places where they sell computers. But they’re expensive, and why bother when you can make your own solution for next to nothing?
What you’ll need:
- Distilled water (available at your supermarket; tap water leaves streaks and minerals).
- White vinegar (you may substitute isopropyl alcohol; either way, make sure these substances are diluted before they come near your screen).
- A clean, soft cloth (never use any kind of paper product).
- A spray bottle.
- In the spray bottle, mix the distilled water and alcohol/vinegar, in a 1:1 ratio.
- Turn off the LCD display.
- Spray the mixture onto the cloth, never directly onto the screen.
- Wipe gently – oh, so gently – from top to bottom. Do it horizontally, too, if you think that leaves a cleaner result.
- Let the screen dry before turning it back on.
Fingers leave dirt and oil smudges that must be cleaned off. Also, every time you touch the screen you risk doing damage to those tiny creatures inside that hold the colored flashlights. Keep your fingers to yourself.
