New year's resolution: A clean Mac

It’s that time again when Mac users make their New Year’s resolutions. How about a simple pledge to keep your computer clean? I’m not talking about deleting cache files or removing old apps you no longer use. I’m talking about your Mac’s screen and keyboard, or its dusty, grungy innards. It’s not difficult to do, but keeping a clean Mac can help it run smoother, and keep you from getting sick as well. Here are a few ways you can keep your Mac looking new and fresh.

Clean that keyboard

It’s fair to say that the dirtiest part of your Mac is its keyboard. Even if you wash your hands every time you sit down to type, the keyboard collects the germs and sweat from your fingers, and the dust in your room or office. This can make for sticky keys and transfer cold viruses, or worse.
First, unplug your keyboard from your computer or, in the case of a wireless keyboard, remove its batteries. (If you’re cleaning a laptop keyboard, shut down the computer and unplug the power adapter.) Blow out the dust and, if necessary, vacuum the space between the keys (or under them, depending on the type of keyboard you have).
If the keys themselves look dirty, put a drop of standard dishwashing detergent in a glass of water. Soak a soft cloth in this concoction and then wring it out until it’s barely damp. Now wipe the cloth over the keys to get rid of the grime. Rinse the detergent out of your cloth, wring it out, and then finish up by wiping your keyboard off again. Be very careful not to get water under the keys. You should do this regularly, to make sure that no germs fester under your fingers.
You might prefer using alcohol wipes. Since the alcohol evaporates, there’s no risk of liquid damaging the keyboard, and it’s a better disinfectant than soap. (Note: if you want to disinfect a keyboard or input device that many people use, Apple has instructions here.)

Prevent the keyboard from getting dirty

The iSkin ProTouch keyboard protector is easy to wash and you can choose from multiple colors. (There's even a glow-in-the-dark version.)
If cleaning your keyboard proves a mighty chore, or if you have a new one you want to protect from pet hair, cookie crumbs, and the like, you might want to use a keyboard protector, such as the iSkin Pro Touch, a silicone keyboard protector that’s easy to wash, starting at $25. You can get one for your desktop keyboard and for your laptop, so when you’re out in a coffee shop, you can make sure that no stray liquids get under your keys.
An even thinner option is the $25 Moshi Clearguard CS for an Apple Keyboard or $30 ClearGuard FS for the Apple Keyboard with Numeric Keypad. Moshi also offers a line of Clearguard protectors for laptop users.

Get rid of dust

While most Macs today are designed so you can’t open them, the Mac Pro remains the one model that’s easy to get inside. Unfortunately, because of the way it’s designed, it also collects a lot of dust. I had one for several years, and found I had to clean it every few months. If you open the Mac Pro—after turning it off, of course—you can use a vacuum cleaner to remove dust from some parts of it, notably the CPU and RAM areas. If you slide out the hard drives, you can get further inside the Mac Pro and get dust out of the nooks and crannies. A can of compressed air can help get dust out of the tightest corners, but if you use this, you should take the Mac outdoors.
Dirty card
Without regular cleaning, the inside of your Mac can get dusty and stop working properly.
Other Macs are harder to de-dust. The iMac, for example, has inputs below the display and a large exhaust at the top, behind the display. If you have a powerful vacuum cleaner, you can suck some dust out of the bottom, but it’s not easy, and probably won’t help much.
The current Mac mini doesn’t seem to collect a lot of dust, but you can open the round bottom cover and check inside to see if there’s an accumulation of dust, pet hair or anything else that your vacuum can remove.
Note: If you’re worried about static electricity from the vacuum zapping your Mac’s insides, use a battery-powered vacuum or just haul the computer outside and use a can of compressed air to blow the dust out.

Clean the screen

I keep a microfiber cloth—the kind you use to clean eyeglasses—handy to clean my Apple display. Sometimes I see little spots on the screen; I just breathe on them, the way I do with my glasses, and use that cloth to wipe away the offending grime. Apple recommends that you use a soft, slightly damp, lint-free cloth to clean screens more thoroughly.
I’ve never used any special monitor cleaning solutions on my Macs, though if you spill something on your laptop, for example, and get something really icky on its screen, you may need to go that route. You can buy many kinds of monitor wipes, pre-treated with appropriate cleaning solutions, and these are probably good to have just in case of a disaster. Check iKlear and RadTech for options.

Clean behind the screen

I had an iMac that went for service a few months ago, and when it returned, I thought it had a dead pixel. Looking closely, though, I realized that there was a bit of dust behind the screen; actually, between the display’s plastic cover and the actual display. To my surprise, it was easy to remove the front cover to clean this out.
Find a suction cup, at least a couple of inches wide. Press it onto the black bezel near the top of the display. (Don’t worry if it covers the visible part of the display; you can clean off any marks it leaves later.) Pull gently, and you’ll find that the plastic cover of the display comes right off; it’s held onto your Mac or your display by magnets. (This is the case for Apple’s current and recent iMacs and displays that have black bezels around them.) Clean off the inside of this cover, with a soft cloth, and put it back in place starting from the bottom edge, then let the magnets do their work. You can watch a helpful video of this process here.)
While you don't need to be obsessive about cleaning your Mac, these simple tips can help you spruce it up regularly—that’s an especially good idea if you have a laptop that you tote around wherever you go.
