Many people struggle with a dirty mouse. Accumulating dirt and grime on your mouse can affect its functionality. Therefore, you may not be able to use your system properly. You must learn how to clean computer mouse properly to prevent the risk of further damage.
To clean mouse, you must avoid using excessive water or cleaning solution, harsh chemicals or alcohol-based cleaners. These often tend to damage the internal components and coating, which can prevent you from using it properly. This article guides you on how to clean your computer mouse properly without any damage to it.
Part 1: How Does a Computer Mouse Get Dirty?
While you may not think of it much, a computer mouse can get dirty for a wide range of reasons. It is crucial to clean mouse frequently. Some of the common reasons why a computer mouse gets dirty so often include the following:
- Dirty desk surface
It’s the surface your mouse sits on. Therefore, it is essential to clean the dirty desk surface frequently. If the desk surface is messy, it can clog up the underside where the optical sensors are located. Therefore, it will hamper the functioning of your mouse.
- Grease
Grease is one of the most common issues that leads to the computer mouse being dirty too often. Many people prefer eating snacks at their desks. The sticky residues, grease, and crumbs from the food can transfer to the mouse surface. If you don’t clean your hands and start using your mouse, it creates an unpleasant and sticky surface.

- Bacteria and Dust
Bacteria and dust affect the mouse more often. For example, you sneeze into your hands and then start working. This leads to excessive germ transfer, which will stick to your mouse’s surface for far too long. Now, if you share the computer with others, the germs will stick. Always prefer using a mouse with clean hands to avoid damaging it.
- Sweat
Long telephone calls and hot weather can cause your hands to sweat. Moreover, if you use the mouse for too long, sweat builds up and accumulates in the crevices of the buttons. The moist surface can then attract a lot of dirt, affecting the functioning of your mouse. It creates a sticky surface.
Part 2: How Often Should You Clean Your Mouse?
You should clean the computer mouse regularly. Therefore, cleaning it once a month should be fine. However, if you share your computer and others are using it too, you may prefer cleaning once a week. Otherwise, you can schedule the cleaning based on usage.
Part 3: How to Clean a Computer Mouse?
It is essential to follow a detailed, step-by-step procedure thoroughly to clean the computer mouse. Here’s how you can clean the computer mouse without damaging it:
Unplug From the Computer
Disconnect the mouse from the computer. If it is a wired mouse, you can remove the wire before beginning to clean. On the other hand, if it is a battery-powered mouse, you can remove the batteries. This is done to prevent the risk of accidental clicks while you’re cleaning the mouse.
Exterior Cleaning
You have to be very prompt about exterior cleaning of the mouse. To avoid damaging it, use a lint-free, preferably a microfiber cloth, to clean the mouse. As for the cleaning solution, you can use 70% isopropyl alcohol.

Dip the microfiber cloth in the cleaning solution and gently wipe the surface of the mouse. You will also need to clean the buttons and scroll wheels. If there are any textured areas on the mouse, make sure to clean it as well. If there’s stubborn dirt, you may use a cotton swab or toothpick. This dirt is usually located around buttons and crevices. Therefore, make sure to remove it carefully.
Remove Stubborn Dirt
Stubborn dirt, if not removed in time, can damage your entire mouse. It is extremely crucial to remove the stubborn dirt using a toothpick or cotton swab. You need to remove the grime from the top of your mouse. After that, you can use the toothpaste to clean mouse crevices and buttons.
Compressed Air
Compressed air cleaning is one of the safest ways to clean a computer mouse. You must ensure that you’re holding the computer mouse properly, preferably upside down. Then, you can fire short bursts of compressed air to remove dust and debris.

Compressed air cleaning is most effective in areas that are difficult to clean, such as the small spaces beside buttons or the scroll wheel. You have to be extra careful while using compressed air. Therefore, you must not blow the air directly into the sensor area. Doing so may increase the risk of the mouse being thoroughly damaged.
Sensor Cleaning
Sensor cleaning has to be one of the most sensitive aspects of cleaning the mouse. If you’re using an optical mouse, you need to be extra careful while cleaning the sensor lens. It is advisable to clean the sensor lens with a dry cotton swab to prevent the risk of permanent damage.

As for cleaning solutions, you must avoid using extra liquid or pressure. An excessive amount of these things can put additional pressure on the mouse, leading to permanent damage.
Once all these are done, you must leave the mouse to dry for some time. Use a dry cloth to wipe the mouse multiple times and remove any extra moisture or cleaning solution. After the mouse is completely dried, you can connect it to your system. Then, turn on your mouse and check if it is working correctly.
Conclusion
Now that you have learnt how to clean a computer mouse, make sure to do it properly. Your computer’s mouse is one of the key components of its functioning. You wouldn’t want the mouse to be damaged anytime soon. It is advisable to clean the mouse frequently to prevent excessive dirt and grime from damaging it.
