CleanWave Sanitizing Wand
What the what?! A magic wand for fighting germs? Using the same technology employed to sanitize hospital equipment for the past three decades, this ultraviolet light–emitting tool is said to kill bacteria on all sorts of hard surfaces. It works without chemicals, so it’s safe on electronic devices, like keyboards, remotes, and phones, as well as countertops and doorknobs. (But, no, not on germy humans and pets. We were wondering, too.)
