Oil for TT bearing - any advise?

How about some opinions on how to clean out the bearing housing before adding new oil, assuming one is restoring an old idler or direct-drive type. Would you use a solvent to remove dried residue, for example? If so, what solvent is safe? Thanks.

Thanks for the "tip"on Q-tips. I've got bushels of them in the house, but I would imagine that it's very important NOT to leave any stray strands of cotton behind. I would first try wipes meant for microscope and camera lenses; those papers are made not to shred during use and are at least somewhat absorbent. I did a search on Vinyl Asylum, and for my Technics SP10 MkII, synthetic motor oil in either 5W50 or 5W40 was recommended by two persons, and no one objected vigorously. Pure ethanol would seem to be a good choice as a solvent for removing any residue when cleaning the bearing housing of old tt's, so thanks for that, too. As for detergent-based motor oils, I would tend to avoid them in a tt bearing. The detergent action is not needed anyway.
