If your mouse suddenly starts malfunctioning, it might be due to dirt build up inside.

The good news is they are easy to clean. It requires few tools and just a couple minutes of your time to get your mouse running again.

What You Need to Know About Cleaning a Computer Mouse

This isn’t something you need to be tech savvy to do.

Matter of fact, anybody can do this simple task, no matter how much experience you have with computers and their components.

Supplies You’ll Need for Cleaning a Computer Mouse

  • Microfiber cloth or cotton swab- This is for cleaning out the inner parts of the mouse. You’ll want to make sure the cloth is lint free and when using the cotton swab, be sure not to leave pieces of it inside the mouse
  • 70% alcohol- Used for sanitizing and cleaning the mouse. Don’t use other cleaners as they can damage the mouse. If your alcohol is stronger than 70%, dilute it with some water before using it.
  • Clean, lint free rags- You’ll be using these to dust and dry the mouse when you’re done
  • Toothpicks- These will be used to get into the tiny crevices of the mouse so you can dig out all of the gunk build up
  • Screwdriver (optional)- This is only if you need it to remove the top of the mouse to clean it thoroughly.

How to Clean a Computer Mouse (5 Steps)

Step 1: Gather Supplies and Unplug the Mouse

Gather everything you need to clean your mouse, so you have it handy.

If your mouse plugs into the computer, make sure to unplug it so you don’t get shocked when cleaning it.

If your mouse is wireless, simply turn it off and remove the batteries before you begin cleaning.

Step 2: Outer Cleaning

Take the dry cloth and wipe the outside of the mouse down. You can use a touch of alcohol on the cloth if your mouse is sticky.

Next, you’ll take the toothpick and work it through the crevices of the mouse.

Be sure to get under the buttons of the mouse, especially if clicking was a problem.

This will help remove excess buildup that might interfere with the function of the buttons.

Step 3: Clean with Cotton Swab and Alcohol

Turn the mouse over and spray some alcohol on your cotton swab. It shouldn’t be dripping since liquid inside the mouse can cause you even more problems!

It should be damp enough to clean but not drip.

Using the cotton swab, clean all the areas of the mouse you used the toothpick on then work on all other areas of the mouse.

When you are ready to clean the sensor of the mouse, use a clean part of the cotton swab or a corner of the microfiber cloth.

Lightly brush the cotton swab or cloth across the sensor so you don’t damage it.

Let the alcohol dry.

Step 4: Remove the Top

If you want to clean the inside of your mouse, you can remove the top of it (if it is removeable) to reach some of the inner parts of the mouse.

Some just slide off while others require a screwdriver to remove. Follow the manufacturer’s instructions on removing the top of your mouse.

Use a cotton swab to clean the inside of the buttons and remove any excess gunk that might have become trapped in the mouse.

You might be surprised what can make its way in there!

Step 5: Reassemble

Once you’ve cleaned the mouse thoroughly, let it dry.

After the alcohol is dry, you can begin putting your mouse back together.

Then, you can plug it in (or turn it on) and test out your newly cleaned mouse!
