Well, you don’t know everything even though you like to claim you do. By the way, if you actually thought about it instead of spouting off to hear yourself, greasing after you use it, is before you use it the next time. Try greasing a machine at -20f that has sat overnight and then try greasing it after it has been run for a while. Huge difference in how well it takes grease. Also when everything is warmed up from working, you will push out more of the contaminates that have worked their way in during use.
