Apparently paper towel + Windex is a no-no when it comes to cleaning your computer or television's LCD screen. Apple's official guidelines for proper cleaning are as follows:
- Turn off the computer or display. You may need to turn off the computer in order to turn off some Apple displays.
- Dampen a clean, soft, lint-free cloth or paper with water only.
- Wipe the screen. Do not spray liquid directly on the screen.
Easy enough. BUT, if you find you're out of paper towels and don't want to splurge on a special lint-free cloth, coffee filters will do the trick, as well.
"It turns out that those little rippled cones of blotting paper that filter your morning brew are perfect for clearing the dust from your television screen or computer monitor.
They'll catch the dust and cut static on the screen, all without leaving behind any fibers like paper towels would."
