If you feel you have to remove the lube, you might have used too much but...
using a bit too much is far safer than not using enough, if/when you get a case stuck, you'll err on the "too much" side afterwards.
Now to get it off just put a cap full or two of mineral spirits in the corncob and vibrate the loaded rounds for 15 or 20 minutes. They'll come out clean, shiny and dry.
