Now the computer is an indispensable tool in our daily life. All machines need careful maintenance, so your computer also needs regular cleaning no matter its components or the storage space. For some users who have never cleaned their computers, this job might make them a little unsettled because they don’t know how to set about doing it. Therefore, we make a guide to help you clean your PC.

How often do you need to clean your PC?

Usually, you need to clean your PC once a year, but it depends on where you use it.

For users who have pets, you might need to clean your PC more often, like 3 months at once since the pet fur will entangle in the fans and block more dust and other shards in the computer. While users who smoke, keep the habit of cleaning computers once every half year.

Meanwhile, placing your computer on the floor makes it easier for dust, hair, skin cells, and carpet particles to enter. Particles are less likely to enter your computer if it is elevated off the floor, such as on your desk.

Clean the case of your PC with PC cleaning kit

▶ Part 1. Tool preparation

You’ll need to buy some basic tools to clean your PC.

We strongly advise against using a vacuum to remove dust from your computer components. This can cause static electricity to build up and potentially destroy crucial electrical components on your motherboard, video card, and elsewhere. It's simply a horrible idea, all you need is a compressed air can.

And there are some other tools you might need:

• Screwdrivers
• Zip ties
• Scissors
• Cotton swabs

You can use anything you need during the cleaning work.

▶ Part 2. Clean your PC

Now we can clean the computer. Please shut down your PC, and remove all peripheral devices like mouse, keyboard, external drives, etc.

Step 1. Open the case or the cover of your laptop with screwdrivers. If you've never opened yours before and are having difficulty, examine your computer's handbook or try searching online for information unique to your model.

Step 2. Please remove any components that may be readily removed so that you can clean them more completely. You can remove RAM sticks, video cards, and hard drives from most desktop computers. You may, however, keep everything installed, if you don’t know how to install it back.

Step 3. We do not suggest removing your CPU since the thermal paste used to transmit heat from the processor's top to the fan must be replenished every time the fan is removed.

Step 4. Use compressed air to blow the dust area. If you remove RAM, you can clean the RAM slot with air.

And you can clean the CPU fans in the same way. Please use a pen or pencil to prevent the fans from spinning.

Step 5. Use a damp (not wet) cloth to wipe the bottom of the case, and then use the compressed are to blow the dust away.

Then you can install all removed components back, close the case and boot your PC.

Clean disks with PC cleaning tools

After we clean the dust in the computer, now we move to the next stage to clean the disk and system junk files. Unfortunately, it’s impossible to find all the junk files that hide deep in your system and disks by yourself. There are numerous data files and folders on your disk and you’ll never know which the crucial files are for all programs you installed.

The outdated temp files, cache files, and program files can spread in every corner of your storage capacity and store the needed files, you could only use the PC clean tool to filter them and clean them.

Just like you use PC cleaning kits to clean dusk, you can use AOMEI Partition Assistant Standard to clean the junk files on your disk. It’s a free disk and partition management tool for Windows 11/10/8/8.1/7/XP users. The “PC Cleaner” function can scan your disks and system to find junk files and after the scan, users can easily clean their computers with one click.

Step 5. When you see a correct symbol displayed in the interface, you can click "Back" to leave the function.

Now, the junk files are cleaned. If you need, you can try “Delete Large Files” to filter large files that may no need for your OS, and remove them to release more available space on the disk.
