  You know your laptop is filthy. You can see the dirt and grime on your
keyboard. You can see that circle of skin oils on the middle of the trackpad. So
when’s the last time you cleaned it?
          Using a freshly cleaned laptop is almost as satisfying as getting a brand
new one. The keys are clean, the screen is free of smudges and you fall in love
with that three-year-old MacBook all over again. It’s also a useful skill if you
buy or sell used laptops, since the previous owner doesn’t always leave them in
pristine condition.
          Gather Your Supplies
          “You don’t need much to clean a computer,” said Jolie Kerr, New York Times
contributor, cleaning expert and host of the podcast “Ask a Clean Person.” “I
use exactly four things to keep my laptop clean: Rubbing alcohol, microfiber
cloths, cotton swabs and canned air.” Ninety percent or higher isopropyl alcohol
is ideal, since it won’t damage the internal components. And if you have some
particularly tough grime or oil, a Mr. Clean Magic Eraser (or other melamine
sponge) can also work wonders, though it should be a last resort since it’s
          “清洁电脑不需要太多东西,”《纽约时报》的撰稿人、清洁专家、播客“请教干净人”(Ask a Clean Person)的主持人乔莉.克尔(Jolie
          Don’t bother with specialty cleaners you see at big box electronics stores
— they’ll work fine, but they’re probably overpriced compared with what you have
at home. “Some people like having them, or they feel better about using an
Officially Sanctioned Product,” Ms. Kerr said. “That is fine! They also make
nice add-on gifts for people who are getting a new computer/tablet/phone for a
special occasion.” But don’t feel like you need them.
          Start With the Inside
          Once you’ve gathered your tools, it’s time to start cleaning the inside of
the computer. Tackling that grime on the keyboard may be tempting, but Ms. Kerr
said you should start with the less glamorous internals: “Canned air will blow
crumbs and cat hair and what-have-you everywhere, so if you’ve already cleaned
the screen and bezel, you’ll just end up having to clean them again after you’ve
used canned air.” Start by blowing out the dust, then move on to the
          Provided you’ve maintained your laptop well, you shouldn’t have to open it
up for this step. Just turn off the laptop, unplug the power cable and remove
the battery (if it’s easily removable). Grab your compressed air, give it a
quick burst away from the laptop to get rid of any condensation, then start
blowing air into any cracks and crevices: the keyboard, the vents and even the
USB ports. Blow in short bursts, since longer sprays can cause moisture to
accumulate inside your computer and can damage the fans by making them spin too
          If you’re lucky, you probably won’t see a big change after doing this. The
goal is to prevent dust buildup over time, which can cause your laptop to
overheat. If there are visible dust bunnies in the vents, you’ve let it go far
too long without a cleaning. In that case, you may want to open it up (if you’re
comfortable doing so) or take it to a repair shop for an in-depth cleaning.
Smokers and pet owners should take special care to clean the inside often, since
you’re likely to experience much quicker buildup of dust, smoke, hair and other
          Wipe Down the Outside
          Next comes the fun part: making that laptop shine again. “The most critical
thing when cleaning a laptop or desktop computer is to apply the cleaning
product to the tool you’re using to clean, never ever directly onto the
computer,” Ms. Kerr said. So grab your microfiber cloth, pour a few drops of
alcohol onto it, wring it out so it isn’t dripping wet, and go to town on the
surface. You may want to use cotton swabs and alcohol for the keyboard keys and
the small spaces between them. (If there are marks that won’t come off, you can
try rubbing them with a Mr. Clean Magic Eraser very lightly, but again, they’re
mildly abrasive and this can alter the finish of the surface.)
          It may take a few passes to get all that grime off, but once you do, you
should notice a dramatic difference. If your laptop is particularly old, you may
not be able to get rid of the shine on the keys; some of us may type like the
Incredible Hulk and have worn down the top layer of plastic. There’s not much
you can do about that.
          The screen is a slightly different matter. You should be able to wipe
fingerprints off with a dry microfiber cloth, but if you need a bit more
cleaning power, a little bit of water — again, poured onto the cloth and wrung
out first — can go a long way. Some manufacturers, including Dell and Lenovo,
even say you can use a 50:50 mixture of isopropyl alcohol and water, if need be.
Just avoid household cleaners with harsh chemicals like ammonia or alkaline on
the screen. (That means no Windex, as tempting as it might be!)
          Get Rid of Nasty Smells
          Let’s say you have a particularly terrible case of gross laptop, and even
after the above steps, your laptop still carries the stench of … whatever you’ve
subjected it to. I’ve seen more than my share of laptops that smelled like smoke
(cigarettes and otherwise), and getting rid of that is a challenge. Cleaning the
surface can help, but a lot of those smells may also be inside the computer. For
that, you can turn to the world’s best natural deodorizer: charcoal.
          You don’t have to go digging through your grill for briquettes, though. Ms.
Kerr recommends kitty litter: “Because most kitty litter formulas have active
charcoal in them to neutralize litter box smells, it’s a great odor eliminator.
Seal the laptop up in a bag or closable bin with a cup or so of the litter and
leave it for 24 to 48 hours.” If you don’t have a cat, I’ve also had good luck
with diaper pail deodorizers, which are neat little packets of charcoal you can
throw away when you’re done. The longer you leave the computer in the bin, the
          If you’re comfortable taking your computer apart, you can also open it up
and clean off the board with isopropyl alcohol. But in my experience, this isn’t
usually necessary — it just speeds up the process a little bit.
