Cleaning your computer from inside and outside may improve its performance. When too much dust starts to accumulate on the fans, vents and components, it becomes more difficult for the machine to keep its cool. If the temperature at which the computer runs is higher than such a device can tolerate, it affects  performance. In a word, it starts to go more slowly. Sometimes this can have more serious impact on the machine. In particular, some parts may stop working, which means you will have to replace them with new ones. As you probably don’t want to go that far, we suggest you start cleaning right away!

Desktop Computer

If your PC doesn’t look good or you cannot see much of it due to the dust that has accumulated, then it’s time to give it a nice clean.

Here we will give you some tips to cleaning a desktop computer, including the keyboard and mouse. Grab some cleaning products and tools and get it started.

How to clean your PC

Before you proceed to cleaning, don’t forget to unplug the machine. Make sure it is turned off. If you have recently used it, wait for at least half an hour before you start cleaning. Apart from the fact that the components need to cool down completely, this will also lower the risk of electric shock that may damage the computer or injure you.


Use a vacuum cleaner to remove the dust from the vents and other parts of the machine. Be careful not to catch on some gentle parts and damage them.

Use a cloth or rag (slightly damped or dry) to wipe down the entire surface.

Keyboard, monitor and mouse

With a microfiber cloth, wipe down the monitor. You can use a cleaning product here but make sure it is appropriate to use with computers.

Wipe down the mouse and keyboard. Don’t push too hard on the keys or screen. Be sure to remove all particles and dirt that may have stored in these components. In addition, you can vacuum the keys to remove the dust, other bits and food particles from the inside of the keys.


Now that you have done the easy task, proceed to the more serious one: cleaning the interior. It’s time to open the machine and clean what’s inside.

In order to clean the inside of the computer, you need some technical skills. The tools you are going to use are: cleaning rags and cloths, soft brushes (paint brushes or make-up brushes also make do), a can of compressed air and a vacuum cleaner. A switch cleaner may also be required. This is a spray that removes dust.

Start by removing the side panel. If there are screws, take them out. You can now vacuum the interior. It can be wise to remove any memory chips, cards for port extensions, networks, audio, video and add-on in order to obtain better results but this isn’t necessary.

Do not surprise if you encounter spider webs inside. It is amazing how much dust and dirt a PC can hold.

Use a brush and can of compressed air to dust off the interior. Be careful wen using compressed air. Use it only in short bursts. When you are done with that, you can use rags or cloths to wipe down the surface.

When the clean is over, put all part back in their place. Reassemble everything you took out of the computer. Be careful when placing the chips and cards. They need to be sealed well so that they can work. Have a check of all the components to ensure they are all right where they belong. When you’re done with this step, wait for another half an hour before you start using the machine again.
