- Do make sure your computer is turned off before you attempt to clean it.
- Don't use typical household cleaners for your computer's delicate screen. Ingredients like acetone, ammonia, and alcohol will break down a LCD screen.
- Do use a microfiber cloth, especially for the screen. Use light and rapid circular movements to clean without streaking.
- Don't use paper towels, even on your computer's exterior; the roughness can cause scratching.
- Do use compressed air, Q-tips, and a very small amount of cleaner to clean keyboards. Don't put them in the dishwasher. Yes, there are plenty of stories of dishwasher success, but usually only after a few days of drying. There's really no reason to subject your keyboard to that kind of force unless the manufacturer recommends it.
- Do seek out cleaners made specifically for electronics, but don't spend outrageous amounts of money on them. A mixture of white vinegar and distilled water will work fine, too.
