Cleaning your Desktop PC

  • PrintPrint
This document pertains to all HP and Compaq Desktop PCs.
This document tells you how to clean your PC, monitor, keyboard, and mouse. Dust, pet hair, and other particles can accumulate on or inside your desktop PC. These particles can scratch hardware components and they can build up, shortening the product life by causing overheating. Cleaning your desktop PC can make it last longer by getting rid of this potentially damaging buildup. It is recommended to inspect your system for cleanliness once a month as part of a regular maintenance program.

Before You Begin

WARNING:Before cleaning the PC and components, perform these steps to reduce the risk of electrical shock:
  1. Turn off the PC and monitor.
  2. Unplug the power cord from the PC and monitor.

Cleaning the PC

Periodically check the PC case for dirt and dust. Make sure to check the cooling vents and I/O ports for dust buildup. Use the following sections to clean your PC case.

Cleaning the PC Case

If the computer case has accumulated dust and buildup, follow these steps to clean:
  1. Use a clean, dry cloth to dust the PC case.

  2. Use a clean cloth dampened with warm water to wipe it clean.

    If sticker residue is present, use isopropyl alcohol or rubbing alcohol and a lint-free cloth to remove the residue.

  3. Use a clean cloth to dry.

Cleaning the Cooling Vents

The cooling vents allow air to flow through your PC and help keep it cool. Buildup inside these vents impedes the cooling process. Use a battery-powered vacuum to remove dust and buildup from the vents.

Cleaning I/O Ports

The computer has a series of ports, usually in the back. Dust and debris can collect in these ports, reducing connectivity and performance. Use a battery-powered vacuum to remove any debris that has accumulated in and around these ports.

Cleaning the Monitor

Periodically check the monitor for dirt and dust. Make sure to check the monitor vents and screen for dust buildup. Use the following sections to clean your monitor.

Cleaning the Monitor Case

If the monitor case has accumulated dust and buildup, follow these steps to clean:
  1. Use a cloth dampened with warm water to wipe the monitor case clean. If sticker residue is present, use isopropyl alcohol or rubbing alcohol and a lint-free cloth to remove the residue.

  2. Use a dry, clean cloth to dry.

Cleaning the Monitor Vents

Your monitor vents allow air to flow through your monitor and help keep it cool. Buildup inside these vents impedes the cooling process. Use a battery-powered vacuum to remove dust and buildup from the vents.

Cleaning the Monitor Screen

Use a clean, dry cloth to clean the monitor screen. For more thorough cleaning, use an antistatic screen cleaner and a clean cloth. Anti-static screen cleaning wipes can be purchased from many computer supply stores online at minimal cost.

Cleaning the Keyboard and Mouse

It is recommended to clean the keyboard and mouse whenever you clean the computer and monitor.

Cleaning the Keyboard

Debris particles can accumulate between and beneath the keys of your keyboard. Gently use a battery-powered vacuum to remove debris particles that get between and beneath the keyboard keys. Use a low setting to avoid removing key caps and springs.
