How to Clean Your Household Gadgets

LED TV screens are fragile, so don't let harsh paper towels or chemicals anywhere near them. Use a lint-free, microfiber cloth to gently wipe down the screen. If a stubborn mark persists, pour a 50/50 solution of water and rubbing alcohol into a spray bottle, spritz on the cloth and wipe down again. Don't apply the solution directly to the TV and don't press down on the screen, which could cause pixels to burn out.

Since your smartphone goes everywhere with you, pack individually wrapped tech-cleaning wipes in your purse or car. Make sure the wipes are specifically designed to clean screens and electronics and have antibacterial properties.

When a dusty cooling fan is a computer's problem, look to the laundry room. Dryer sheets work double duty to safely clean a computer's parts without interfering with its electrical system. As for a keyboard — that's seen its share of mess. Use a can of compressed air or a small brush to knock crumbs out of those nooks and crannies.

Check your device's manufacturer's instructions, as many companies advise against using any sort of chemical on a touch screen. A 50/50 water-to-alcohol solution can be used with a microfiber cloth on the back of the tablet. To be safe, opt for a water-only damp (not wet!) cloth on the screen.
