Cleaning Your Computer

It's important to keep your computer clean, not just because it looks nice, but also because things like dust, dirt, and crumbs can affect your computer's performance. However, there is a right way and a wrong way to clean your equipment. This guide will show you the safe and effective methods for cleaning your computer case, monitor, mouse, and keyboard.

Safety First: Before You Clean

Before you clean any part of your computer, always turn it off and unplug it from the power outlet. This is for your safety and to protect the equipment from damage. If you are cleaning an older keyboard or mouse with a round PS/2 connector, make sure the computer is fully shut down before you unplug and plug it back in.

Cleaning the Keyboard

Keyboards can easily collect dust, crumbs, and other debris between the keys.

  • General Debris: Turn the keyboard upside down and gently shake it to dislodge any loose particles.
  • Deep Cleaning: For a more thorough cleaning, you can use a can of compressed air to blow dust and dirt out from between the keys.
  • Surface Cleaning: To clean the surface of the keys, use a soft cotton cloth or paper towel lightly moistened with rubbing alcohol. Never pour alcohol or any other liquid directly onto the keyboard.

What to Do If You Spill Something:

  • Immediately shut down your computer and disconnect the keyboard.
  • Turn the keyboard upside down to let as much liquid as possible drain out.
  • If the spill was something sticky (like soda), you can try rinsing the keyboard under running water. After rinsing, let it drain upside down for at least two full days to ensure it is completely dry before you try to use it again.
  • The best way to avoid this problem is to keep all drinks away from your computer area.

Cleaning the Mouse

Optical Mouse (most common): These mice don't have moving parts and require very little cleaning. The only thing to check is the small light sensor on the bottom. If a piece of dust or hair gets stuck over it, the mouse pointer may jump or not move smoothly. Simply wipe the area with a soft cloth.

Mechanical Mouse (older type): If you have an older mouse with a tracking ball on the bottom, you can clean it by twisting the circular cover counter-clockwise to remove the ball. Wipe the ball with a cloth and rubbing alcohol and gently scrape any dust off the small rollers inside the mouse.

Cleaning the Monitor

Your monitor is sensitive, so it requires gentle care.

What NOT to Do:

  • Never spray water, cleaner, or any liquid directly onto the screen. It can leak into the monitor's casing and damage the electronic components inside.
  • Never use glass cleaner (like Windex). The chemicals can damage the special anti-glare coating on many modern screens.

The Safe Method:

  • Make sure the monitor is turned off and unplugged.
  • Use a soft, lint-free cloth (a microfiber cloth is perfect) and moisten it slightly with water.
  • Gently wipe the screen. Do not press hard.

Cleaning the Computer Case and Workspace

The case that holds your computer's components can get dusty, which can block air vents and cause it to overheat.

  • The Case: Wipe the outside of the computer case with a lint-free or microfiber cloth.
  • Vents and Fans: If you see a lot of dust buildup in the ventilation fans on the back of the case, you can use a can of compressed air to blow the dust out. This helps keep your computer running cool.
  • Maintain Airflow: Make sure there is nothing blocking the fans on your computer case. Don't stack books or papers against the vents. Good airflow is essential for keeping your computer from overheating.

By cleaning your equipment regularly and using the right methods, you can keep your computer looking good and running healthy for years to come.
