Let’s see how to clean your mouse with isopropyl alcohol and other nifty tools.

What you will need:

  • Q-tips or a microfiber cloth: Microfiber clothing leaves no fibers behind. Q-tips are intended for cleaning narrow and difficult to access areas.
  • Toothpick: For even narrower areas where your Q-tip won’t reach.
  • Isopropylic alcohol: Alcohol to sanitize and disinfect your mouse against viruses and bacteria.
  • Dry and clean rags: To dust and dry your mouse before and after cleaning.

Mouse cleaning process

  1. Disconnect your mouse from your computer. If it is a wireless mouse, turn it off and remove the batteries to avoid damage.

  2. Clean with a pad all the cracks, curves and crevices that collect dirt and grime on your mouse. To do this, use a microfiber cloth and a cotton swab dipped in alcohol.

  3. Remember to clean your mouse sensor, otherwise it may cause tracking issues. Gently rub the sensor with your alcohol-soaked cotton swab.

  4. Now flip your mouse over, roll the scroll wheel to remove the dirt accumulated around it, and wipe that area with your microfiber cloth.

  5. Finally, use the toothpick to remove unwanted dirt, grime, and grime from areas that your Q-tip couldn’t reach the first time around. Flip the mouse over and clean up any dirty areas you may have missed.

Disassemble your mouse

Once you have cleaned your mouse from the outside, we need to clean it from the inside, so that it not only looks new, but also looks like a new mouse.

This may vary depending on your mouse design, but it should be pretty straightforward. If in doubt, search YouTube for your mouse and watch some teardown videos.

  1. Take a fresh cotton swab and apply alcohol to its tip as before.

  2. Clean any areas where you see a buildup of dust. You may need to use more than one Q-tip here, as the dust build-up inside your mouse is usually greater than outside on the surface of your mouse.

  3. Look for dirt on the scroll wheel and circuit board. Be very careful, as this area is very sensitive and you may damage something otherwise. You can use tweezers here if needed.

  4. Wait until everything is dry, then go back up. Alcohol usually dries out fairly quickly, so you might only need to wait a minute or so.

Here is! You should now have a shiny new mouse like you bought it on day one.
