How to clean gunk off of an optical computer mouse
Gather your equipment.
To clean your optical mouse, you will need the following items :
Q-tip or microfiber cloth-for cleaning gunk off of the mouse. If possible, use a microfiber cloth since it won't leave behind fibers like a q-tip will.
Isopropyl alcohol-for cleaning and sanitizing. Do not use a different cleaning agent (e.g., windex)-if you don't have isopropyl alcohol, use water.
