Simply place your cell phone in your PhoneSoap and close the lid. During a 10-minute cycle, a powerful UV-C light kills 99. 99% of household germs*. When the external blue indicator turns off, your cell phone is completely clean. With their DNA broken, bacteria can’t function or reproduce, and the organisms die. In the PhoneSoap’s controlled environment, UV-C light effectively and safely sanitizes your cell phone, as well as anything else that fits inside your PhoneSoap like remotes, keys, tablets, and more.
