I had to clean a hundred of them every quarter for a couple of years (work study was in the computer lab).
Since the build up was oils from people’s hands you needed the right cleaners.
The balls got tossed into hot soapy water. Soak them for 10 minutes and they came out clean.
The rollers inside the mice were the worst. They required a Q-tip with some acetone or rubbing alcohol. For the really stubborn ones, I pulled out the naptha.
