How to Clean Your Computer Inside and Out

Computer Stuff, How To Articles

Computers have become an essential part of our daily lives. We rely on them for work, communication, and entertainment. However, as we use them daily, they tend to accumulate dust, dirt, and grime, which can slow down their performance and affect their lifespan. Therefore, it is essential to clean your computer regularly, both inside and out, to ensure that it functions at its best. In this article, we will provide a comprehensive guide on how to clean your computer thoroughly.


Cleaning the Outside of Your Computer

Cleaning the exterior of your computer is an easy task that you can accomplish with a few simple tools. Here are the steps:

Step 1: Turn off your computer and unplug all the cables. This is an important safety precaution to prevent any electrical hazards while cleaning your computer.

Step 2: Use a microfiber cloth or a soft-bristled brush to gently wipe down the exterior of your computer. Be sure to clean the top, sides, and bottom of the case. This step will remove any visible dirt, smudges, and fingerprints.

Step 3: For stubborn stains or smudges, use a small amount of rubbing alcohol or a specialized computer cleaning solution on a microfiber cloth. This step will help remove any tough dirt that won’t come off with a simple wipe.

Step 4: Don’t forget to clean the keyboard and mouse. You can use a can of compressed air to blow away any debris between the keys. You can also use a soft-bristled brush to remove any visible dirt.

Cleaning the Inside of Your Computer

The inside of your computer is where the critical components reside, such as the CPU, motherboard, and power supply. Over time, these components can accumulate dust, hair, and other debris, which can affect the cooling system and cause your computer to overheat. Therefore, it’s essential to clean the inside of your computer regularly. Here are the steps:

Step 1: Turn off your computer and unplug all the cables. Again, this is an important safety precaution.

Step 2: Open the case of your computer. The process of opening the case may vary depending on the type of computer you have, so refer to the manufacturer’s instructions.

Step 3: Use a can of compressed air to blow away any dust or debris from the internal components, such as the CPU, motherboard, and power supply. Make sure you hold the can upright and use short bursts of air to prevent any liquid from coming out.

Step 4: Use a soft-bristled brush to gently remove any remaining dust or debris. This step will help remove any dirt that the compressed air couldn’t remove.

Step 5: If the fans inside your computer are clogged with dust, use a cotton swab or a toothbrush to remove the dust. Make sure the fans are completely clean, and their blades are not obstructed. Clean fans will help improve the airflow inside your computer and keep the components cool.

Step 6: Carefully reattach the case of your computer, making sure all the screws are in place. This step will help prevent any debris from entering your computer.

Additional Tips for Cleaning Your Computer

Use a Vacuum Cleaner: If you want to remove the dust and debris that has accumulated in the crevices of your computer, you can use a vacuum cleaner. However, be careful when using a vacuum cleaner as it can generate static electricity, which can damage the sensitive electronic components in your computer. To prevent this, make sure to use a vacuum cleaner with a static-free hose.

Use Isopropyl Alcohol: Isopropyl alcohol is a great way to remove stubborn stains and smudges from your computer’s exterior. Simply mix equal parts of isopropyl alcohol and water and use a microfiber cloth to wipe down the affected area. Make sure to wring out the cloth well to avoid any liquid from seeping into the computer.

Schedule Regular Cleaning: Regular cleaning is essential to keep your computer in good condition. Set a schedule for cleaning your computer, depending on how frequently you use it. For example, if you use your computer every day, you might want to clean it every two to three months.

Keep Your Computer in a Clean Environment: The environment in which your computer is situated can affect how quickly it gets dirty. Try to keep your computer in a clean environment and avoid placing it on the floor or near an open window.

Consider Upgrading Your Components: If you find that your computer is still running slowly, even after cleaning it, consider upgrading your components, such as your hard drive or RAM. These upgrades can help improve your computer’s performance and extend its lifespan.


In conclusion, cleaning your computer regularly, both inside and out, is essential to ensure that it runs smoothly and lasts longer. By following the simple steps outlined in this article, you can keep your computer in good condition and prevent any damage from occurring. Remember to be gentle when cleaning your computer, avoid using harsh chemicals, and always follow the manufacturer’s instructions. A clean computer not only performs better, but it also looks better, and it can help you get the most out of your investment.
