How to Fix a Computer Mouse if It Gets Wet

By Brendan O'Brien

Your computer mouse is like any other electronic device in that moisture spells trouble. In general, if you spill a drink on your mouse or any other electronic, you need to move quickly. Irreversible damage can occur quickly. Also, you may ultimately need to purchase a new mouse since your efforts may not be warranted for the amount of money that you can spend on a mouse these days.

Step 1

Unplug the mouse from the computer. This is extremely important because liquid and electricity is a dangerous mix. It also makes it easier to work on your mouse when it is unplugged.

Step 2

Wipe it dry with a rag or towel. Do this as quickly as possible. You may be able to save much of the moisture from creeping inside of the device if you move quickly.

Step 3

Take the mouse apart with a Phillips screwdriver. The object is to expose the inside of the device to air.

Step 4

Turn on a fan and lay the mouse next to it. Air drying devices is a good solution. Let the fan run for several hours.

Step 5

Check to see if there has been any blue or green powder substance forming around any of the circuitry. If so, that means the device has started to corrode.

Step 6

Re-assemble the mouse and plug the mouse back in to the computer to test it.
