Cleaning and disinfecting programs are key for the public to feel safe venturing out to shop, eat and relax. The same regime is being practiced at home too with certain disinfecting cleaners still in short supply. However there has been growing interest in using ultraviolet light as an eco-friendly cleaning product that is not in short supply. Marketers are selling UVC light wands as cleaning agent, claiming the UV-C waves destroy the virus. While you are aware of UVA and UVB waves anytime you've been out in the sun too long, UVC rays are blocked from the sun by our atmosphere. So while scientists say UVA and UVB light can damage and destroy a virus, it is a slow process. It remains to be seen if UVC light is an effective way to kill coronavirus. If you decide to use a UVC light wand for cleaning purpose, there are some very important safety facts to keep in mind. UVC can affect skin cells the same way UVA and UVB rays do, in that it can cause mutations and lead to skin cancer. Looking at UVC lights can cause irreversible blindness, too. Look for UVC devices that come with safety switches, such as an automatic “turn-off” buttons that halt the light emission as soon as you're at risk of direct exposure. Another thing to consider is the legitimacy of the product. Seeking out FDA-approved UVC devices are going to be a little more reputable because they're thoroughly examined. But most are tailored toward industrial and medical facilities. However just because a wand is FDA-approved doesn't mean that they aren't using UVC light. But you should make sure the product comes from a reputable company and has good reviews.
