How to keep your phone clean and rid of germs and viruses

You spend all day with your phone, setting it down on tables, chairs, public benches, bathroom counters, and even more unsightly places. And you can't always see the germs, dirt, grime, and potentially even viruses, your phone is allowing to call home. As we deal with COVID-19, keeping our phones clean and sanitized is of greater importance than ever before. But thankfully getting them clean again can be easy, if you know what to use.

What NOT to use when cleaning your phone

Lysol or Clorox wipes might seem like an easy way to clean grime off a phone, and the perfect way to fend off COVID-19. But fight this instinct with every phone-loving fiber of your being. Bleach, vinegar, alcohol, and most harsh disinfectant chemicals can clean the sides and back of an Android phone or iPhone, but those chemicals need to stay far away from the glass front of your phone (and glass back if you have one), as they will eat away at the oleophobic coating that your phone uses to help fight fingerprint smudges.

What if my oleophobic coating is already gone? Or I don't care about it? The oleophobic coating wears down naturally over time, so if yours is already gone, then feel free to go to town with some Lysol wipes, just be careful as you do. Make sure you don't let the liquid from the wipe seep into any ports or pinhole mics, and make sure you let the solution dry completely from the phone before you re-apply your case. These chemicals don't play nice with the interior components of your phone, and if they seep in far enough to trip the water damage sensor most phones have these days, you might not be covered for a warranty replacement if something shorts out.

Compressed air can be useful since it blows dust out of hard-to-reach places. However, you need to be very, very careful when using it with a phone as compressed air can damage pinhole mics and other components quite easily with their precise, pressurized air blasts.

How to clean your phone by hand

t
1. Take your phone out of its case. If it's made of safe-to-wash materials like TPU/silicone and hard plastic, give the case a good rinse in warm water and let it air dry.
   Note: If your case is made of leather or other luxury materials, try looking for cleaners specific to your material. The maker of your case will likely have cleaning guidelines on their website or in the box the case came in.
t
2. Using the cloth and polyurethane foam-tipped swabs in the Phone Cleaning Kit (or Q-Tips, if you've got the time to whittle the tips to points) to gently swab around the earpiece, speaker grills, and various ports on your phone.
t
3. Be extra careful when swabbing the USB-C/Lightning port not to leave any fibers behind or dislodge any pieces inside the port. If one of the larger swabs doesn't fit in your USB-C/Lightning port, use one of the mini brushes included in the Phone Cleaning Kit instead (or a small, soft toothbrush).
t
4. Take a Zeiss Mobile Screen Wipe and wipe down the screen and body of the phone. While the Zeiss Wipe doesn't have the harsh chemicals Lysol or Clorox wipes will, its evaporative pre-moistened solution should still be enough to remove the top layer of grime and germs from your phone.
t
5. If any streaks remain after using the Zeiss wipe, use a microfiber cloth (or a clean, non-embroidered kitchen towel) to wipe the screen clear of streaks.
t
6. Once the phone and case are both completely dry, re-apply your case to your phone.

If you don't regularly use your headphone port - or just tend to acquire more dirt and lint in your ports than normal - consider investing in a set of dust plugs to help keep your port clear and clean when not charging. Also, if you'd like to cut down on grime accumulated on your screen/case when you use your phone, put your phone down for a few minutes and go wash your grimy hands or apply some hand sanitizer before getting back to browsing Reddit. Or try not to use the phone at all while running errands, using wireless earbuds if you need to answer a call and checking messages by glancing at a smartwatch instead, for example. When you get home, don't take it out of your pocket or purse until you've had the chance to thoroughly wash your hands.

Seriously, clean your hands, ya filthy animal!

The easiest way to disinfect your phone

There are solutions you can make by diluting isopropyl alcohol that can disinfect a phone, but again, you generally want to avoid alcohol and vinegar as they'll eat through your oleophobic coating. If not that, what's a girl to disinfect with instead? UV! Ultraviolet lights can kill bacteria and disinfect your phone with just a few minutes inside a doll-sized tanning bed.

There are a few versions of these UV phone baths out there. The HoMedics UV-Clean Phone Sanitizer is a neat option worth considering. It uses UV-C LED sanitizing and patented pop-up technology to sanitize both sides of your phone in about a minute, and it doesn't use any mercury or chemicals. Designed to kill 99.9% of bacteria on your phone, it even collapses flat and fits in a case so you can bring it with you. The rechargeable LEDS last for thousands of uses. If you have a super-sized phone like the Galaxy S20 Ultra, you'll want to opt for one like the F7F9 UV Smart Phone Sterilizer Box to ensure your phone fits. It also has an aromatherapy mode to add a nice, fresh scent to your phone!

I like to bathe my phone and case separately so that no grime can hide under the cracks and crevices of the case, but you can stick your phone in the case and kill all of the surface bacteria on your phone. Consider investing in one of these sanitizing devices and running your phone through it at least once a week, or whenever you head out to run errands.
