How to Clean Your CPU (PC)

To keep the CPU and case of your PC clean and in top operating condition, it’s a good idea to clean it regularly. This will get rid of dirt, dust, residue, and any other nasty bits and pieces that tend to stay on the surface or inside of your monitor screen.

Can I Clean My CPU and Case By Myself for Free?

There is a cheap and simple way to clean a computer screen which is free, environmentally safe, and will not ruin your CPU and case if you follow the manufacturer recommendations for that purpose. Here are some tips on how to clean your computer monitor screen. Make sure that you read your computer screen manufacturer guidelines so that you don’t undo what they tell you about cleaning your machine.

Let’s begin to clean but hold on safety first!

To be on the safe side read and follow the guidelines of your PC CPU manufacturer for cleaning and disinfection.

Your CPU Cleaning Kit

You will need the following 10 tools and products to clean your CPU at home. Tools will facilitate you in cleaning and the cleaning products will actually remove dir, dist, and residue from your PC CP and it’s case.

1. Cleaning fluid (for computers)
2. Wipes (for PCs)

4. Compressed air can

CPU and It’s Case Cleaning Procedure

The surface cleaning of the computer CPU or tower case is straightforward. With the help of a vacuum cleaner (with a pointy nozzle and brush attached) extract all the dust, hair, and other particles from the vents of the tower case. This will allow cool air circulation tot he motherboard, hard disk, and other internal electronic components of the PC and will ease the cooling burden on the computer fan and heatsink. Don’t use the compressed air can as the air blast will push the dust and particles inside the CPU. Don’t use water or any other liquid for the CPU cleaning as it can cause a short circuit. With the help of a cotton bud and cleaning brush gently clean the computer fan. Using a vacuum cleaner extract all the dist and particles from the fan. Make sure that the air extraction doesn’t pull the fan or spin it as it can easily damage the fan.


You can achieve almost the same cleaning results as a professional will do. The trick is to take your time and use quality products when cleaning your CPU. When you clean your CPU or it’s case the 2nd and 3rd time by yourself, the experience with time will give you better results. Save money by cleaning it your self!


As a best practice, you should clean your CPU regularly to increase its performance and extend its lifespan. Perform surface cleaning every single day and deep cleaning once in a week if possible. Keep your CPU away from food and drinks.
