Phone Soap: Charge and Clean Your Phone 

You may charge your phone every day, but do you clean your phone as much? Whatever your hands touch, your phones touch. It has been discovered that some phones have 18 times more bacteria and viruses than any surface in a public restroom. So it probably won't surprise you that a 2011 University of London study found that one in six of our phones have bacteria and viruses on them--specifically, the bacteria called E. coli. 

The research on bacteria and viruses led to the invention of Phone Soap. It is not actually liquid like dishwasher soap. It is a phone charger that uses the electromagnetic radiation used in hospitals to kill 99.9 percent of bacteria and viruses, cleaning your phone while it charges. 

"There are really certain types of bacteria and viruses that we should not be in touch with, and they are really on our phones," says Wes Barnes, the Phone Soap co-founder. It all started while his cousin and co-founder, Dan LaPorte, was in his cancer research lab at college. "He realized he got the idea of getting rid of bacteria and viruses on the phones," said Barnes. "In the lab they used UV-C light for destroying them. He realized this would be the fastest, most powerful way to kill any bacteria and viruses living on electronic machines." 

Phone Soap looks like a little metal suitcase. Your phone rests in to charge and get cleaned at the same time. Instead of plugging your phone into the wall, you'd plug it into the Phone Soap charger box. The process only takes a few minutes but, Barnes says, "The idea is that you can leave it in there overnight if you want to keep charging. Reflective paint keeps the light completely around the phone so it cleans the phone fully." 

The co-founders spent 2013 finding the right companies and they started shipping the product in late November. By last week's International Consumer Electronics Show in Las Vegas, Phone Soap was all grown-up. Both co-founders have left their previous jobs and are selling Phone Soap nonstop. "We're shipping almost more than we can handle each day," Barnes says. "It's been a great adventure." (End of story)
