 Disgusting! The unpleasant side of touchscreens. We love our phones and we love our tablets. We love our touchscreen devices. We don't love smudgy fingerprints on our screens. Microfiber cloths work well to wipe away prints. But microfiber cloths do not sanitize the screen. And germs love touchscreens. Those germs can cause colds, pink eye and diarrhea. Apple tells us that alcohol and cleaning chemicals can damage our touchscreens and they recommend not using them. So how do we get rid of all of those germs on our touchscreens? One way to kill bacteria without damaging the screen is to use an ultraviolet sanitizing light. Simply hold the wand a few centimeters above the screen for several seconds. Of course, it's always a good idea to wash your hands before and after using your touchscreen. After all, who wants to get sick from using their technology?
