Remove the rust as completely as you can… electrolysis, evapo-rust, wire-wheel in a drill, etc… once you get it removed, give the part a good wipe down with a dilute phosphoric acid solution. You can find the stuff at the BORG pretty cheap… such as this: Klean-strip Prep-n-etch

I mix the above about 50/50 with distilled water. Remove the rust, and then give it a good wipe down with the acid solution. It will take care of any hidden stuff remaining. Then just before painting, I will usually give it a wipe down with acetone to remove any residual crap. As a benefit, with that method – you don’t need to prime first… just paint with a good oil based enamel and it will be fine. I have machines that I’ve restored that were severe rust buckets, and not a lick of rust has returned.
