Computers, like any other object in your home, will collect dust, hair and other debris which can get stuck in it. Plus, any time you or your family touches the computer you will leave germs on its surface. However, if you clean your computer regularly with a few simple tools you can keep it from getting too dirty.
A cloth is a good tool for cleaning a computer because, unlike paper towels, they shouldn't leave lint or other paper debris after you wipe down your computer. The cloth should be lint free and will be good for wiping down any surface of your computer.
A can of compressed air will help you remove any packed in dust from your computer's fan and any other hard to reach crevices. All you have to do is blow the air into the crevice to loosen the particles from your computer.
For computer cleaning you can use either pure isopropyl alcohol or 90 percent to 70 percent isopropyl alcohol. Just make sure not to use an ethanol based alcohol. The alcohol will help clean germs from your computer.
Cotton swabs are handy for cleaning in hard to reach places on your computer. Just dip the cotton swabs into the isopropyl alcohol and use them to clean areas where the cloth won't reach.
A low powered vacuum is great for sucking out the dust and other debris that can get inside of your computer. You can use the vacuum to clean out the computer's vent or the inside of the computer. However, it is dangerous to use your regular vacuum because it generates static electricity which can harm your computer.
