- Of course your bearings will eventually need to be replaced, but many people would like to know the proper maintenance process to prolong a bearings life. There are several ways to do it, an ultra-sonic cleaner is the best, but you can also soak the bearings in the citrus cleaner. You may need to shake the bearings around a little to loosen up some of the debris and then let soak, remove bearings and clean the citrus cleaner off right away with water. Your bearings should now be clean and ready for lubrication that will need to take place right after cleaning. We suggest using J&T's Verde Grease or Advantage Bearing Oil for the best results.
