How to Clean a Mouse Scroll Wheel [Easiest Methods]

A computer mouse tends to get dirty very quickly, and the buildup of debris can cause it to become less responsive or even stop working. Whether you use your mouse for work or for gaming purposes, a clean scroll wheel is essential for a seamless experience.

Why should I clean the mouse scroll wheel?

There are not one but many reasons why you should consider cleaning your mouse scroll wheel regularly. Some of the obvious ones are: 

• Cleaning your mouse screen wheel preserves the life of your computer mouse and keeps it working properly. 
• Food particles and dead skin cells clogged in the scroll wheel can damage the internal mechanisms of the mouse. 
• A dirty mouse scroll wheel makes it difficult to scroll the web pages and affects your productivity. 

Now that you know why keeping a mouse scroll wheel clean is necessary, let’s proceed to the different methods to clean the mouse scroll wheel without investing much time and effort.

How do I clean a mouse scroll wheel? 

1. Things you need 

1. Compressed air can – To blow away the dust or debris stuck on and around the scroll wheel
2. Q-tip/Cotton swab – To clean the scroll wheel with disinfectant. 
3. Jeweler’s screwdriver – To loosen the small screws that hold the mouse panels together 
4. Isopropyl alcohol – To disinfect the scroll wheel and clean the oil buildup.
5. Microfibre cloth – To wipe and dry the scroll wheel and internal circuit of the mouse

2. Cleaning Process 

1. Unplug the mouse and remove the batteries if it is a battery-powered wireless mouse.
2. Turn over the mouse such that its bottom faces upwards. Identify the screws that hold the panels together and use a jeweler’s screwdriver to loosen and remove them, keeping them in a safe place. Some models have a central screw instead of several screws. 
3. Gently lift the top panel upward to remove it and reveal the scroll wheel and internal circuit. Remove the wheel and both attached springs by pulling the plastic assembly upward.
4. Hold the can of compressed air about four inches above the wheel and the internal circuit. Now blow short bursts of air on each side of the wheel to remove all trapped dust and debris particles. Repeat the process until the mouse looks completely clean.
5. Dip the Q-tip or cotton swab in isopropyl alcohol and gently wipe the tip around the wheel’s circumference to clean away any oily buildup and dirt. 
6. Use the microfibre cloth to dry the scroll wheel and internal circuit, and maintain extreme caution. 
7. Once the internals of the mouse is completely dry, place the wheel back and reposition the assembly in the center. A small click sound will ensure that the wheel is well seated in its correct position. 
8. Now fit the top panel back in place, flip over the mouse to replace the screws, and tighten them using the screwdriver. 
9. Test your mouse to make sure it works flawlessly.
