How Often Should I Clean My PC?

To ensure that your PC runs smoothly and lasts longer, it is important to keep it clean. Generally, it is recommended that you clean the dust inside your case every three to six months and dust the surfaces every week.

However, if your PC is on the ground, near a window, or in a closet, it is more prone to dust buildup, so you should clean it every two months. If you have hairy pets like cats or dogs, pet dander and hair tend to accumulate on parts quickly, so it is advisable to clean your PC at least every two months. Or, if you live in a hot, dry area, you should be more careful about dust buildup to help prevent damage to your components.

Why Should I Clean My PC?

Keeping your PC clean is essential to ensure its longevity and optimal performance. Neglecting to clean your computer can lead to a buildup of dust and debris, which can cause various issues. Here are some reasons why you should make cleaning your PC a priority:

If you have a habit of eating at your computer, it’s easy to ingest these germs without realizing it. Regularly cleaning your PC can help lower the chance of getting sick and protect your health.

Cleaning your PC is crucial to ensure its longevity, optimal performance, and your health. It’s a simple task that can prevent various issues and save you time and money in the long run.

How To Clean Your PC

Proper cleaning of a PC is essential to keep it dust-free and improve its longevity. This section covers the internal parts of a PC and how to clean them. Peripherals are discussed in a separate section.

1. Preparation

Before starting the cleaning process, it is important to gather the necessary tools and supplies to avoid wasting time and making mistakes. The required tools include a can of compressed air or a piece of lint-free cloth, a brush, toothbrush, screwdriver, some cotton swabs, and rubbing alcohol.

It is important to turn off the PC and unplug the power cable from the rear and let the PC cool down. Disconnect all the cables and peripherals, making sure to note where each cable goes to avoid mistakes when reconnecting them. Press the power button multiple times to ensure no static electricity is lingering in the components.

Remove the side panels of the case, and if the front panel is detachable, remove it too. Keep the case near an open window or door to get fresh air while cleaning. Alternatively, move the case outside before removing the panels.

2. Getting Rid Of Dust

If the user is not tech-savvy, simply removing the dust from the case is enough. There is no need to clean the individual components. Use a lint-free cloth or can of compressed air to clean the dust from any dust filters and any obvious deposits in the base of the case. Do not blow the compressed air too close to the components as it may damage them. Also, make sure the fans do not spin while pushing air into the case, as the dust in the air can penetrate the fan bearings and ruin the fluid that allows the fans to spin.

Dip a toothbrush into rubbing alcohol and clean the fan blades gently. After cleaning, put the parts back together again if not planning on cleaning the components. Always wear a mask when opening the PC to avoid the fine grains of dust from getting into the lungs, causing irritation and allergic reactions.

3. Cleaning The Components

If the user wants to go all the way, it is time to clean the CPU, graphics card, and power supply unit.

Instead, ask a technician to clean them for you.

1. CPU

It is not necessary to clean the CPU itself, but the cooler and sockets should be cleaned. This step does not require removing the CPU from the case.

First, disconnect the cooler from the motherboard and take it out. Blow compressed air to clean the dust from the heatsink. Use a brush to remove the remaining dust from the fan and around the sockets. Use some rubbing alcohol and a piece of lint-free cloth to remove the old thermal paste on the CPU. Apply a dot of new thermal paste. Remember that less is more when it comes to using thermal paste. Put the cooler back on and tighten the screws.

2. Graphics Card

Take the graphics card out of the case to clean it thoroughly. Use compressed air and a brush gently to remove the dust. Make sure the fans do not spin to avoid dust entering their bearings. Hold the can upright so that none of the liquid air can escape. Do not shake the can.

3. Power Supply Unit (PSU)

Restricted airflow in the PSU causes overheating, potentially damaging some of the capacitors that already run very hot. Use a screwdriver to remove the screws that connect the PSU to the PC. The power supply has an intake and an exhaust: the fan is the intake, and the mesh grille is the exhaust. Both of these parts need to be cleaned.

Start cleaning with the intake. First, stop the fan from moving and then use the compressed air to blow dirt off this part. Blow into the fan until sure all the dust has been removed, and repeat this process for the mesh grille.

After completing the deep cleaning process, put all the parts back together again. The PC is now clean and ready to work at full performance.
