Best way to clean & lube trackball bearings?

[markrvp]

I have an older Betson Imperial 3" trackball that is dirty on the inside.  There is some dirt and grime on the rollers and bearings.  Could somebody please tell me the best way to clean the bearings and rollers?  Also what is the best lubricant to use and how should I apply it?

I usually use denatured alcohol.
It cleans well, and then flashes off--leaving no residue.
As long as it doesn't leave residue, pretty much anything will work.

Also what is the best lubricant to use and how should I apply it?

3-in-1 oil, and very lightly.
