Cleaning a Mouse Wheel
Cleaning a scroll wheel might seem a complex task, but it’s not as complicated as it looks. This step-to-step troubleshooting guide will save you a lot of time and effort and allow you to get all the dirt and debris out of the wheel.
Now that you are aware of the reasons to clean the scroll wheel, it is time to reveal the three methods to clean the mouse wheel.
Method #1: Using a Q-Tip or Tooth-Pick
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:
- First, keep the mouse under a direct light source and gently spin the wheel to spot any dirt or grime.
- Bring out a Q-tip and dip it in alcohol; rub it all over the wheel to remove grime.
- 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.
Step #4: Remove the Wheel and Springs
Next, get hold of the plastic assembly. You will now be able to spot two springs arising from either side of the scroll wheel. Pull the assembly upward to remove the wheel and both attached springs.

Step #5: Clean the Wheel Using a Can of Compressed Air
Hold the can of compressed air around four inches above the wheel and panel. Fire short bursts of air on each side of the wheel and blow away all the dust and debris particles. Repeat the procedure till the mouse looks completely clean.
Step #6: Reassemble the Mouse
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.
Method #3: Cleaning Without Taking the Mouse Apart
If you are not a big fan of disassembling and reassembling the mouse, this method will work best. This is what you need to do to clean the mouse wheel without taking the mouse apart:
- Unplug the mouse from your PC or computer or take the battery out if you use a wireless mouse.
- Next, hold a compressed air can around four inches above the wheel and spray short bursts of air through it.
- Clean off the mouse using a soft microfiber cloth.
Once you are done cleaning, plug the mouse back into the computer. Surprisingly this method doesn’t require much effort. You can use this method to clean the scroll now and then.
