how to clean bearings?

i got a brand new dv888 and after about an hour of play it went really responsive so i think the bearing needs to be clean. what do you use to clean them?

You can use a cleaner such as mineral spirits or lighter fluid to break down the gunk in the yoyo. There is this handy dandy guide on how to clean it from there.

Mod Edit: Please do not refer to other store sites for info.
We have plenty of the same type of info here.
