According to Digital Trends, a California-based Kickstarter-backed company is trying to change the way we clean things. ESN Tech has developed a new sterilizer that uses ultraviolet light to eradicate 99.9 percent of bacteria on stuff we use every day. The "Klistem" system can be used to disinfect baby bottles, reusable water bottles, toothbrushes, earbuds, and more.
