Gordon,
I'd suggest something a bit differently than using a grinder to clean up the insert posts. I'd use some 400 grit wet/dry sandpaper preferably with a pad sander. Why that? Because a grinder tends to make a surface that is not smoothly flat. True it will get the rust and old paint off really fast - but what you really want is highly smooth surfaces - even if only surface smooth and not all the way down to the metal. IMO you want a non friction prepared surface so sandblasting would also be rougher.
Then when you apply whatever lubricant you decide on - its acting off of smoothness and not a textured surface like a grinder can give. Will 400 grit take a long time? No - because "clean" is not your goal - "smooth" is the goal imo.
P.S. and sand length-ways - not sideways. Also maybe consider a "polymer spray" rather than a petroleum based spray for the lubricant.
