Keeping electronic devices healthy extends their lives; too much dust on electronics makes them unhealthy. It settles and thickens, and can clog their important components, like their fans and even their motherboards. When the fan on your laptop stops working, the computer might overheat and get fried. Regular dusting is the best way to prevent damage to your home entertainment systems and other electronics. Some of these tips come from About.com, and the rest I’ve made up and tried out successfully.
Using a compressed air cleaning duster on electronic devices is one way to go, but these can be pricey, and if they’re not used properly, you can actually push dust and debris farther into the device. For dusting screens, an ammonia free glass cleaner or isopropyl alcohol spray is a safe bet, and cheaper than commercial screen cleaners. Or make your own glass and screen cleaner with 3/4 distilled water, 1 teaspoon of castile soap, 1/2 cup vinegar, 1/2 vodka cup or gin, and 10 drops of an essential oil (like vanilla) to mask the smell, if you choose-this spray works well on mirrors and windshields too. Don’t spray directly onto the electronic screen, because it’s easy to spray too much liquid, which drips inside the machine. Spray a clean cloth first (cotton or microfiber are best), and wipe the screen with circular motions. It’s a good idea to test a small area of the screen with a new cleaner first, to make sure they’re a match. Never use paper towels on screens (or on your glasses); they’re rougher than they look, and can scratch the surface.
For a quick touch up of screens and intake areas of electronics (especially TVs and DVD players), gently brush them over with a dryer sheet. Besides cleaning the electronics, the anti-static elements of dryer sheets keep dust and hair away, for a while. Another low budget dusting trick: use a Q-tip to gently clean the extended tray of your DVD player or laptop. A minute amount of water on the tip will wick up dust nicely. You can also run a Q-tip around your laptop’s keyboard to pick up dust and hair that’s settled in between keys.
