I came across a wireless charger that cleans cell phones with uv light. Also advertised that it cleaned credit cards, key fobs and even pacifiers. Is it possible to clean germs with lights? I don’t understand this sorcery
In: Chemistry
UV light at sufficient levels scrambles germ’s DNA, interfering with reproduction. A small number of pathogens is unlikely to produce enough toxins or otherwise do serious harm, it’s the multiplication into colonies that does the damage.
