How to properly clean a bearing so it will ast for a long time

i have recently acquired some new yoyo bearings and within a few days they are already making my yoyos responsive and have either gotten louder or quieter. i have cleaned my yoyo bearings with mineral spirits before and it helps for a few days and it happens again, how do i get them to work great for long periods of time?

When I oiled mine, they became responsive and loud for a few weeks. Breaking it in by use is better than lube for me.

If you want to oil the bearing, I suggest YYJ thin lube. Just 3 or 4 drops in the bearing.
