Desktop PCs are not as portable as laptop computers, so they sit in the same spot gathering dust. With a weekly dusting, it is not always possible to clean the inside of the computer as well. Compressed air can be used for dust that is located inside the computer or in hard to reach places. However, this task should only be completed by someone who knows what they are doing.
You can start cleaning with compressed air by first turning off the computer and unplugging it from its power supply. Disconnect any equipment that is attached to the computer.
The next step would be to remove the computer case and ground yourself, to prevent any shocks or sparks.
Compressed air can be sprayed towards the areas with noticeable dust on them, being careful not to touch or disengage any connections.
A soft cloth can be used to wipe out the inside of the computer, as long as care is taken to work around the connections.
Afterwards, close the computer's case again, reconnect the equipment that was attached to it, turn on the electrical supply, and boot up your computer.
1. Laptop computers can still gather dust in their fans despite the fact that they are portable.
2. If you are not going to be touching the capacitors in a monitor or power supply unit, the main purpose of grounding yourself is to prevent electrostatic damage to sensitive components, not to prevent sparks. Much damage can occur without any perceptible shocks or sparks.
