Step 1: Precautions to Take Before Cleaning

How to Clean Laser Mouse
If you have a wireless laser mouse, you can usually find a switch off button on the bottom side. If not, just remove the batteries.
  1. If you are using a wired laser mouse, power off your computer and unplug the mouse from the USB port. It’s necessary to do so before the cleaning process so that you don’t get any electrical shock.
  2. If you are using a wireless laser mouse, just remove the batteries.
  3. Your wireless laser mouse may also have a power button. You can usually find this on the mouse’s bottom along with the section for batteries. Turn it off to stop the mouse from transmitting and making use of the battery.

Step 2: The Basic Cleaning Process:

Dirt on the mouse
Dirt accumulated on the pads can hinder the performance and comfort by increasing friction.
  1. Hold the mouse in your hands and look over the pads on the four corners at the bottom. There could be dust, lint, hair, and other particles accumulating over there.
  2. Clean them with a dry paper towel or soft lint-free cloth and remove the lint and unwanted particles by utilizing a toothpick. If dirt is still left, you can remove them with your fingernail.
  3. If the dirt is remaining and not removable with your fingernail or toothpick you can make use of a paper towel or soft cloth that is made slightly wet with water. You can do this by spraying few drops of water on a paper towel or soft cloth with a spray bottle.
  4. Dry the pads with another paper towel.
  5. Use a toothpick to gently reach the tiny hard to reach areas on the top and bottom of the mouse. This includes the crevices around the buttons and the scrolling wheel. It will help to bring out filthy or sticky particles that may be difficult to remove.
  6. You must ensure not to use the toothpick on the mouse’s sensor.
  7. If you have a compressed canned air you can use it to bring out the remaining dirt. This can be done by blowing air into the corners and tiny spots slowly so that the smaller particles and dust that may have settled between the corners are removed.

Step 3: Thorough Cleaning and Disinfecting Process

Slightly dampen a lint-free cloth (with water) and use it to clean your mouse gently and thoroughly to remove dirt all over.

Then use an alcohol wipe to clean and disinfect the body of the laser mouse thoroughly. Alternatively, you can use a lint-free cloth sparsely dampened in rubbing alcohol or a mixture of mild dish detergent and warm water for cleaning and disinfection.

The cloth should not be too much dampened otherwise it may introduce moisture in the mouse. You should not use wipes or cloth in the battery section in the case of a wireless laser mouse.

Use a Q-tip to remove the dust around the laser sensor. Do this gently and don’t press it very hard.

Dry the mouse’s body with a dry soft cloth or paper towel. Also, give the mouse some time to dry completely.

Step 4: The Post Cleaning Process

  1. When you are sure that the laser mouse has dried and there is no moisture or liquid left, reconnect to the USB port in case of a wired one.
  2. For a wireless variant, insert the batteries and turn the power button on. Then turn the computer on.
  3. Resume using your clean laser mouse.

Why Clean Your Laser Mouse Regularly?

Hence cleaning your peripherals is not just neat but critical for your hygiene.

Essentially, if you make a habit of cleaning peripherals like the laser mouse, it would ensure that they remain in good working condition and lead to an increase in their lifespan.

We like to point out that dirt, dust, grime, or other particles especially in the sensor area of the laser mouse could lead to unsmooth and erratic pointer movement on the screen.

This could badly affect your computer usage and lead to annoyances. You can clean the area around the sensor as described above and see if the pointer problem is fixed.
