I use a ultra sonic denture claener to clean and lube my bearings you would be surprised how much fine powderey black material is come out of the bearings. They spin very freely. In the old days I would clean the bearing and soak them in TRI flow and bake them at 150* for 2 hours to give them a teflon coating they would spin like crazy. Now I'm lazy I just clean them every 3-4 race days or before a big race!
