You may use hand sanitizer and then wash your hands once you take off your clothes, but if you’re not disinfecting your phone as well, you most likely aren’t doing enough. A popular 2012 study out of University of Arizona has shown that cell phones often have ten times more bacteria than toilet seats. And that number is surely larger if you use you phone in the bathroom and then lay it somewhere close to the toilet as you flush the latter. In that case, you may get fecal bacteria on your phone too from your flushing, not just the Covid that you bring from outside.

You actually have thousands of bacteria on your mobile phone. A 2017 study regarding the phones of 27 high school students in Estonia found an average of 17,032 bacterial gene copies per phone, including E. faecalis.
With people living alone before Covid, dirty phones probably didn’t pose much of a problem, as our bodies are used to living with lots of bacteria, including many pathogens. But when your immune system is weakened, and you’re also exposed to Covid, contaminated phones pose a problem. They also pose a health risk to people you’re living with, who have different microbiomes in their bodies, because we touch our phones tens of times a day—and then go pick up something from the fridge, touching its handle, along with various other door handles along the way, for instance. Or you touch bottles and food wrappings. You get the gist.

So Today’s Tip is about a UVC smartphone sanitizer from Knizen, which looks to be one of the best on the market at a fraction of the cost of the more advertised ones—and it’s large enough to fit baby bottles as well! So you can easily disinfect keys, glasses, and various other objects besides phones.
A Word of Warning:
Please note that exposure to Ultraviolet C light is extremely damaging to the eyes, skin, and the body in general, so make sure you (or your baby or someone else) don’t open the box until it’s done sterilizing the items inside. It’s best to open the box after the box is done sterilizing AND you have unplugged it. (It’s a good thing this sterilizer doesn’t have a battery!)
This UV-C Light Sanitizer Box, currently selling at $69.98 (affiliate link), has passed a SGS sterilization test for professional-grade equipment. And it has a much larger capacity than the usual phone sanitizers on the market, at 9.5 x 7.7 x 5.9 inches. It’s a high-quality product that comes with a one-year warranty and lifetime customer service.
If you want to test if this Knizen device is germicidal enough, you can buy a UVC Light Test Card, such as the one below from Quantadose. Place it inside the sanitizer box, close the box, run a partial sanitizing cycle for 15 seconds, stop sterilization and unplug the box, and only then open the box. Of course, you don’t really need to test the Knizen machine, as it should work, but I guess you can happen to chance on a defective one, as with everything—which is partly why I advise you to always unplug the box before opening it.
Below is the UVC light tester. You can read more info about it on Amazon (affiliate link).
