Using UV-C light to clean sounds futuristic but it has been used to sanitize surfaces since 1878. The 1903 Nobel Prize in Physiology was awarded for the use of UV light to kill and prevent tuberculosis. It's currently used in medical, food preparation, and water sanitation services, but now the technology has shrunk enough that you can have your own UV sanitizer at home. These handy devices are used to clean everyday objects like phones, wallets, and bags (and consequentially, they make a great cheap Christmas gift).
So how do UV sterilizers work? In order to understand that, we should first talk about what UV light is. We're exposed to ultraviolet light from the sun all the time. Our sunblock protects us from UV-A and UV-B light which can cause sunburns and skin cancer. UV-C light, the kind created by these sterilizer devices, is generally deflected by our ozone layer and never reaches us. UV-C bulbs are not the same as those black light bulbs you find everywhere around Halloween. These are powerful bulbs.
When UV-C light hits microbes, the light disrupts the bonds that hold their DNA together. Without working DNA, bacteria and viruses can't replicate themselves or even perform normal cell functions and say the colony dies off. Which is pretty brutal if you think about it, but also awesome because a light bulb can kill all the bacteria on your bathroom counter.
For more information, this article from Scientific American really spells out things in detail.
How does a UV sanitizing wand work?
First and foremost, follow the instructions that came with the wand because they are all a bit different. If you somehow obtained a wand with no instructions here is what you need to know.
Keep it straight. These wands work best in a flat, horizontal, and downward position. Many have safety features that shut off the lamp if it's turned upright to protect your eyes. If you need to use it on something like a wall or mirror, it can be used vertically, just be sure to keep it aimed directly at the surface so you don't trigger the safety shut off.
Do not shine it on people, animals, or near anyone's eyes. It won't kill you like it will bacteria but your eyes can be severely damaged according to this article from Prevent Blindness.
These wands are most effective on flat smooth surfaces, so they are mainly meant for counter surfaces, manicure tools, and other smooth objects. These wands can kill over 90 percent of all microbes.
It takes at least 10 seconds to be effective. Think of it like ironing--if you pass it over at lightning speed, it won't work. Go slow, work in sections.
Between a half-inch and an inch is the sweet spot for how high off the surface you want to hold your wand. Any closer and it's going to take you a lot longer to cover the area and any higher and the effectiveness goes down.
UV wands can also be handy to travel with, as you can use them to ensure your hotel linens are clean and sterile.
Bacteria and viruses don't stand a chance against a UV sterilizer. Get one to keep your phones, glasses, baby bottles, and other personal items safe and 99.9% germ free.
