Two years ago or something like that I wanted to try trackball. Got me an ELECOM HUGE. Had read in a review that it only became a smooth roller after some use and of course that you have to clean it regularly. Did clean - maybe not that often -, but smooth wasn't in its dictionary.
Now, I'm not very fond of having fats and oils on plastic parts I interact with - like kb, mouse, remotes, trackballs. But, today I thought what the heck and put silicone oil on my trackballs bearings. Should have done that years ago!!
So, I don't know, if silicone oil is the best choice, but if your trackball doesn't agree with you, oil up that sucker.
