Studies have found that computer keyboards have more germs on them than the average toilet seat. Yuck! And that’s just the keyboard. But what about devices like laptops where everything is connected?

When you’re working on your laptop, and you sneeze without covering your nose, some of those particles are going to end up sprayed across your monitor, whether you can see them or not. Or, if your nose is running, and you wipe it with your hand and then use that hand to type, you may have just transferred germs to your keyboard. (This can occur even if you use a tissue.)

Even if you aren't sick, there are many things you probably do while using your laptop that can promote germ and bacterial growth without even realizing it—like eating in front of your computer. When you snack in front of your computer, small particles fall off, lodging themselves in your keyboard and other areas. These can be breeding grounds for germs and bacteria.

While it’s a good idea to clean anything you touch regularly, it is particularly important to clean your laptop and other frequently used technology devices. However, because of the sensitive nature of electronics, you can’t just clean your laptop with any only cleanser you have lying around. Doing so can cause damage and may render your laptop unusable.

In order to properly clean your laptop, you’re going to have to gather a few things. But don’t worry, you probably have most of these items already.

Supplies Needed

  • 70% isopropyl alcohol (not rubbing alcohol)
  • Canned air
  • Cotton swabs
  • Electronics vacuum (optional)
  • Microfiber dusting cloth
  • Spray bottle

Cleaning a Laptop Keyboard

Not only do keyboards have lots of crevices and small unseen areas where crumbs, dirt, bacteria, and other nasties live, but it’s also one of the most touched parts of the laptop. And, because we touch the keyboard with our fingers, we often transfer those germs to our environment, and our person, without realizing it.

Luckily, cleaning your keyboard isn’t too difficult.

  1. Turn your laptop off, and then gather the canned air, cleaning cloths, cotton swabs, isopropyl alcohol, empty spray bottle, and the electronics vacuum (optional).
  2. If you have an electronics vacuum, use it first to suck up any large particles and crumbs on the surface of the keyboard. Note, if you don’t have an electronics vacuum, skip to the next step.
  3. If your laptop is particularly dirty, you may want to take it outside for this next step. Turn your laptop on its side, and carefully spray the keyboard with the canned air, making sure to get all the cracks and crevices.
  4. At this point, you will probably see some large particles coming from your keyboard, especially if it’s never been cleaned before. Continue spraying with air until all the crumbs, hairs, and other particles cease to pour out of the keyboard.
  5. Once it’s cleaned of large chunks, it’s time to actually clean the keyboard. Make a mix of 50% water, 50% isopropyl alcohol in your spray bottle. Mix it together, then spray your cleaning cloth. You want your cloth damp but not dripping wet.
  6. Wipe down your entire keyboard, focusing on any heavily soiled spots. Don’t forget to clean any visible spaces between rows. Wipe down the rest of the keyboard area too, including areas without keys and the trackpad and its buttons.
  7. For stubborn dirt, take some cotton swabs, and dip them in the isopropyl alcohol. Make sure they are damp but not dripping wet. Use the cotton swab to gently scrub any dark spots or difficult dirt areas.
  8. Continue cleaning until your keyboard is clean and spot-free. If it was really dirty, you may be surprised what clean actually looks like.

Cleaning a Laptop Monitor

Once your keyboard is clean, it’s time to move up and focus on the monitor. It is important to only use cleaners that are made specifically for monitors, as some cleaners could mess up your display.

You can pick up LCD cleaner at any electronics or computer store, or make your own. To make some at home, either use a mix of distilled water and white vinegar, or use the 50/50 solution of water and isopropyl that was mixed to clean the keyboard.

First, wipe your monitor with a clean, dry microfiber cloth. This will remove any smudges, like finger prints. Then, spray your cleaning mixture onto the cloth. It should be damp, but not dripping.

While it doesn't really matter how you wipe down your monitor, it’s best to do it systematically to avoid streaks. Try wiping it vertically, moving from top to bottom, left to right, until the entire display is clean. Then, wipe it horizontally, moving from left to right, top to bottom, until you have wiped the entire surface.

If you have stubborn spots, you may want to re-spray a corner of your cloth, and gently work at the spots with the damp corner. Even if you’re cleaning a stubborn area, remember to be gentle as it is easy to damage and scratch LCD's.

Continue spraying the cloth, wiping, and cleaning until your monitor is sparkly and streak-free. Remember to wipe down the plastic surrounding the screen too.

Cleaning the Rest of Your Laptop Case

Once the keyboard and monitor are cleaned, it’s time to clean the outside of the laptop.

Close the lid of the laptop. With your canned air, spray any vents, crevices, or other areas where dust or other large particles can hide. Then, gently wipe down the entire outside with a clean, dry microfiber cloth.

If you have any stubborn spots, spray the cloth with the 50/50 water isopropyl alcohol mixture. For truly stuck on items, dip a cotton swab into the isopropyl alcohol (it shouldn’t be dripping wet), and hold the swab against the stubborn spot for a minute or two. Then scrub at it with the microfiber cloth. It should come up no problem. If not, hold the cotton swab on the spot for a bit longer before scrubbing.

Remember to be careful with how much pressure you put on your laptop while cleaning. You do not want to put so much pressure that you scratch the surface, or worse, crack the case or damage any of the components inside.

Once the outside case is cleaned, you’re done. You can now plug your laptop back in, turn it back on, and begin using it again.

Create a Cleaning Schedule

By now, you've probably realized that cleaning your laptop doesn't take that long. In as little as 15 minutes or less, you could have a sparkling, germ-free laptop that looks almost as good as new.

So why not create a regular cleaning schedule to ensure your laptop always looks its best? Put it on your monthly calendar, and you’ll never have to deal with a dirty, germ-ridden laptop again. And, with regular cleanings, studies may find that your particular laptop is actually cleaner than the average toilet seat.

tebo from New Zealand on February 26, 2013:

I recently bought some electronic wipes which are good. I don't know if you can get canned air in this part of the world but I'm going to look for it. Sounds great. Great hub with lots of good suggestions.

Thelma Alberts from Germany on February 26, 2013:

Congratulation on the HOTD! Thanks for sharing this knowledge. It came handy to me as it´s time again for cleaning my laptop. Voted up and more;-)

JP Carlos from Quezon CIty, Phlippines on February 26, 2013:

Unfortunately I don't type with my toilet seat. So I'm forced to clean my computer especially the keyboard. Great job on this very important task that most people fail to do. Voted Up!

Stephanie Henkel from USA on February 26, 2013:

Everyone in my family has their own laptop and seems to be on it constantly. It hard to imagine how many germs are hiding in the keyboards and other little crevasses. I'm just getting over a bug, and will be sure to use your suggestions for cleaning up my laptop. I especially appreciate knowing how to make my own solution for cleaning the monitor as I'm always afraid of damaging it. Great hub and well deserved HOTD!

Joanne M Olivieri on February 26, 2013:

Thank you, Thank you. I was just thinking the other day about how I need to clean my laptop keyboard and was actually going to Google how to clean it today. Now I will just follow your instructions. Voted up!

JulieStrier (author) from Apopka, FL on February 26, 2013:

Yup, spray those vents out with canned air. I would take it outside before you do if it's really dusty. You could also use an electronics vacuum if you don't have canned air. Or you could wipe them down with a clean, dry microfiber cloth, but that probably won't be as effective as the methods mentioned. Just make sure your laptop is off before you do any cleaning of this type.

Kristen Haynie from Scotia, CA on February 26, 2013:

I've only had my laptop for just over a year, but it's filthy. I use it for work and for play, so I'm pretty much in front of it all day (this includes many meal times). I've been wondering how to clean it, and I couldn't have come across this hub at a better time! Would you happen to know how to clean the vents for the cooling fan? Judging by the amount of dog hair that was lodged in my keyboard, I can imagine the vents are pretty clogged. Would I use the canned air for that, too?

Marites Mabugat-Simbajon from Toronto, Ontario on February 26, 2013:

My laptop is maintained clean with the use of gentle bristled paint brush. Congratulations on Hub of the Day!

JulieStrier (author) from Apopka, FL on February 26, 2013:

Absolutely the electronic vacuum can help with that. If it's stubborn hair, or there's a TON of it, you can also try canned air. Thanks for reading.

Aldene Fredenburg from Southwestern New Hampshire on February 26, 2013:

Great advice! My biggest issue is cat hair, and I am assuming that the little electronic vacuum will help with that.

Robyn Evans on February 26, 2013:

Comfort Babatola from Bonaire, GA, USA on February 26, 2013:

Thanks for your hub serving as a reminder that I need to clean the keyboards and monitors to all of our computers. I usually use the battery powered air brush for the keyboards, but it's been a while since I've done that.

Great hub, and congrats on winning the HOTD award.

JulieStrier (author) from Apopka, FL on February 26, 2013:

Vinegar can be a great screen cleaner when mixed with a little bit of water. Just remember not to spray anything directly on your laptop, and to make sure your cloth / q-tips aren't soaking wet, and you should be fine.

Rose Clearfield from Milwaukee, Wisconsin on February 26, 2013:

Great overview of this important topic! I love how you broke down all of the information in easy to follow steps. Well deserved HOTD.

L.L. Woodard from Oklahoma City on February 26, 2013:

Appreciate these useful tips and easy-to-follow directions for the best ways to clean a laptop. It can be a little frightening to try to do it on my own without such direction.

Great hub; voted up and Shared.

Great hub! It's easy to forget hidden germs on an item like a PC which is used so frequently.

Cynthia B Turner from Georgia on February 26, 2013:

I use vinegar instead of the alcohol to clean my laptop. I hope I'm not damaging anything by using the vinegar.

Very good tips.

KenWu from Malaysia on February 26, 2013:

Chace from Charlotte, NC on February 16, 2013:

I LOVE this hub. Not only am I a cleaner, I'm also constantly on my computer so it bothers me if there is anything weird on my laptop. Some folks don't mind a loaf of bread or two hiding in between their keys but it drives me crazy, lol. I'll remember these tips!
