The filthiest part of you computer is probably its keyboard. It’s the part you touch the most, it’s the part you likely use to catch the debris from your lunch, and it’s the part that you probably never clean, because you don’t look at it enough to get grossed out. And these days, as doctors warn us to wash our hands constantly (and correctly) to avoid the coronavirus, you probably want to make sure that your keyboard is not just clean, but sanitized.

This is a fairly straightforward process, so let’s get started.

Your home is clean and sanitized. You wash and moisturize your hands regularly, and you haven’t left the house in days. By all measures, you’re pretty sure that your home is an oasis from the pandemic outside your door. But then the new MacBook Air, or that emergency delivery of tea leaves from Amazon, arrives. You have just accepted a potential COVID-19 virus carrier into your home. What do you do?

You sanitize it, that’s what. Just like you’ve sanitized the surfaces in your home.

With the COVID-19 virus spreading, you’ve probably never been more thorough about washing your hands. But you quickly defeat the purpose as soon as you touch that disgusting iPhone or Mac keyboard.

It’s true your devices host more germs than apps. So Apple recently updated its product cleaning page, offering peace of mind as we stress out about COVID-19.

Apple has a long support page of links and tips, dedicated to keeping your devices clean and shiny. But what about keeping them germ-free? Even if you only ever use your iMac’s keyboard at home, you probably transferred plenty of unwanted organisms onto it before you started washing your hands properly.

As for your iPhone, it’s probably dirtier than a music-festival toilet. And your AirPods, which you keep touching with your dirty hands all day long? I feel nauseated just thinking about it.

So, how do you keep all this stuff sanitary? It’s easy, even if your local store has run out of disinfectant wipes due to panic buying induced by fears about the COVID-19 virus.

The other day on the metro, I pulled out my AirPods and dropped one on the floor. It bounced over dried and dirty beer stains, and who knows what other filth and bacteria traipsed in on a million passengers’ shoes (and the odd hippie’s bare feet). I gave up on listening to anything on the trip home, and slipped the rescued AirPod back into its case.

Today we’re going to see how to clean AirPods (or any other earbuds). It’s not only hippie toe jam that we have to worry about, either. Because we’re always pushing these things deep into moist holes in our heads, they crust up with earwax and whatever bacteria we have living in our earholes. Happily, cleaning and disinfecting AirPods is not only easy. It’s just about as satisfying as digging a deep-seated booger out of your nose, or picking an almost-healed scab.

Did you know that setting modern materials like silicone down onto traditional furniture finishes like oil and wax, or lacquer, could leave a mark? Judging by the insane clamor on the internet, roughly half of the planet has just discovered this fact, and is blaming it on Apple.

Those HomePod ring marks are a result of the oils in the finish of the furniture being sucked into the silicon base of the HomePod. The good news is the fix is easy, but if you’d listened to your grandmother, you never would have had this problem in the first place.

If you want to clean up your contacts list so you can better utilize the power of keeping track of people’s contact info on your iPhone, you’ll need to clean it up.

My contacts list has always been a mess. I’ve kept a running list, saved to various services and such, since my first iPhone in 2007.

It’s annoying enough that I went looking for an app that will destroy all the crazy duplicates I have on my iPhone. When I found an app called Cleanup Duplicate Contacts, I took it for a spin and found out how easy it really is.

Here’s how it works.

My iPhone 5 camera has gotten some grime inside it, and my pictures are all yucky because of it. I’ve procrastinated taking it to the Apple Store to get cleaned out because, hey, I’m busy lazy.

Luckily, there’s a guy on YouTube whose buddy had the same problem, and he put up a video showing how to clean out the iPhone 5 with a tiny screwdriver, suction cup, can of air, and a plastic non-marring tool.

A quick disclaimer: if you choose to try this fairly simple iPhone 5 surgery, you’re responsible for any damage that might occur. Please don’t email us asking for a replacement iPhone.

It seems that there can be no corner of the niche product universe that can’t be mined and exploited with tasteless “luxury” versions of regular, plain ol’ tools. Today’s example: the Lynktec ArtCloths, which show your “appreciation” for great art in the same way that the tinny ringtone snippet belching from your cellphone shows your appreciation of music.

With iOS 5, iPhone and iPad users started noticing a new curious behavior: app icons that suddenly started “Cleaning…” themselves. Facebook does it. Instapaper does it. Even Twitter does it. But what the heck does it mean?
