Contrary to what people usually believe, it’s not hard to sweep the scroll wheel. However, you need to be a bit cautious while doing it. Here are the steps to follow to clean the mouse wheel using a Q-tip or toothpick: 

  1. First, keep the mouse under a direct light source and gently spin the wheel to spot any dirt or grime. 
  2. Bring out a Q-tip and dip it in alcohol; rub it all over the wheel to remove grime
  3. Next, take out a toothpick and slide it along the ridges of the mouse wheel. 

Slide the toothpick gently to ensure that it doesn’t break. Wipe away any fall on the outside of the mouse. 

Method #2: Using a Can of Compressed Air 

Another method of sweeping the scroll wheel is using a can of compressed air. This is done to thoroughly clean the wheel from all the corners so that no dirt is left. Follow the steps below for this: 

Step #1: Unplug the Mouse 

First, remove the mouse from the computer. Take out the batteries if you use a wireless mouse that runs on battery power. 

Step #2: Flip the Mouse and Loose Screws 

Flip the mouse over and locate small screws holding the panels together. Some models feature only one screw, while others have multiple screws. Use a jeweler’s screwdriver to loosen and remove the screws. Keep them aside in a safe place and flip the device back over. 

Step #3: Pull the Panels Apart 

To pull the panels apart, lift the top panel upward to remove it gently. You will now be able to spot the scroll wheel and the internal circuit. Notice how the scroll wheel is present on the plastic panel as you have to assemble the panels as is lately.

Now, place the wheel back and replace the assembly in the center. You will hear a small click once the wheel is placed correctly. Fit the top panel back to its place, flip over the mouse to replace the screw, and tighten them. 


Plug the mouse back into the computer and test to ensure it’s working properly now.
