How Do I Clean My Computer?

You know you shouldn't, but admit it, sometimes you eat and drink near your computer. Maybe you have kids who like to poke at your screen or you just take your computer with you everywhere. No matter how you treat your computer, it's bound to need a good cleaning sooner or later. Smears on the screen, gunk on the trackpad or mouse, stuff under the keyboard, all kinds of things can make your computer not only look gross, but also affect its functionality.

The first thing I generally recommend is to give it a good spray down with some canned air. You can buy canned air from most electronic stores or departments (picture below), and it really is just pressurized air in a can. Keep the can upright, aim at the keyboard and/or heat vents and spray. This will kick up a lot of the small things hiding out below your keys or in the vents that keep your computer from working smoothly. Note: Do NOT hold the can upside down! Canned air contains small amounts of liquid nitrogen that can freeze items on contact. This can be dangerous not only to your computer, but to yourself as well.



To clean the body of the computer you have more options. There are numerous sprays, wipes and other things sold that you can apply to the outside of your computer to get stuck on gunk off.  Make sure you verify that it's safe to use on your kind of computer and the parts of the computer you're looking to clean. For example, Macs are made out of an aluminum alloy that may smear when cleaned with some products (I've had good luck with iClear on my Macbook Pro), and even on PCs, some cleaners aren't designed to work on the screen of the computer and can discolor or smear as well.

If you're looking for something cheaper than actual computer cleaner, a common item held in my electronic-cleaning arsenal is good old denatured alcohol and a microfiber cloth. Microfiber clothes are inexpensive and don't leave any small fibers when used for cleaning unlike paper towels, cotton balls or dish rags. Put a small amount of alcohol on the cloth (NOT on the computer directly) and wipe the area that needs cleaning. The added benefit of using alcohol is that it also works as an anti-microbial, killing any germs that may be lingering on your precious device. This is also the way I recommend cleaning a computer monitor, or any electronic screen for that matter.

Practical Tip of the Day: NEVER EVER ever use water to clean your computer! Remember, water is bad for electronics, so keep it far away. Most computer cleaners are made to be used sparingly, and if you use alcohol to clean your computer, make sure the cloth is damp, but not dripping. Even a small amount of liquid can cause irreparable damage to your computer!

Why is Water Bad for Electronics?

It's happened to more Americans than not. An electronic device- iPods, radios, phones, hopefully not toasters- falls into or is otherwise in contact with water. Sometimes it's not water. I've lost count of how many times I've met people who've spilled soda on their laptops, put an iPod through the washing machine, dropped their phone in the pool, and the list goes on and on. This inevitably leads to a frantic Internet search on how to save their device, but the most potential damage is done within the first few seconds. So, exactly why are liquids bad for electronics?

It's all simple science. Electricity moves through matter- be it solid, liquid or gas. Some things conduct electricity better than others, and water is a very good conductor. The way modern electronics are made, electricity travels around the device through tiny wires that connect all the different parts. When water gets introduced to device, the electricity can spread and go to parts that aren't supposed to get electricity, and give more electricity to parts than they're designed to handle. This essentially electrocutes the device. This is the point where the most potential damage happens.

Now, if your device is turned off when it gets wet it's less likely to suffer major damage, but since few portable devices ever turn off completely there's usually at least a small current of electricity going through them. As far as other problems with getting your electronics wet, you also need to account for material other than water in the liquid. For example, if you spill a soda, the acid can corrode parts as well as make it sticky. Pools have plenty of chemicals, as so washing machines, and I won't even go into the additional problems when you drop a device in the commode!

So what can you do to prevent or minimize the damage of liquid to your electronics? The easiest thing is to keep them away if possible. Don't take your iPod to the beach, or drink your wine next to your laptop. Secondly, if your device does get wet, turn it off right away if it's on- this will turn off the electrical current going through those wires and hopefully minimize further damage. Lastly, once it's off, keep it off for at least 24-48 hours, preferably in a room with low humidity. There are other suggestions on the Internet, but none that have been proven to work.

Practical Tip of the Day:
If you need to take your electronics to a place with potential moisture, there are lots of things you can do to protect it. If you're going to the beach, put your electronics in a baggie. This will help protect against both water and sand. If you canoe, kayak or even scuba dive, they make water-proof cases for most cell phones and MP3 players. They even make water-proof headphones! For your laptop, a simple plastic cover over the keyboard helps cover the easiest point of access for spills of all kinds. This also helps keep crumbs, dust and other matter out of your keyboard as well.
