I recently acquired an old 4" Prentiss bench vise. It works perfectly, except that I can't remove the pin in the top that allows the fixed jaw to swivel. It has a wonderful patina (I know, that just doesn't sound manly does it?), with only the slightest of surface rust in a few spots. I don't know if these vises were ever painted from the factory, but I would like to preserve the patina (there's that word again) so I need some advice on what to use to clean it with. I have wiped it down with WD-40, but would like to give it a good once over with something to remove some of the caked-on grease. In other words, I need to use a cleaning agent that isn't abrasive enough to get down to the bare metal. Also, can someone recommend a good lubricant/grease to use? Thanks!
