Looking for recommendations for removing rust from a Pre Model 10. It was possibly a Police Issue. Most of the bluing is worn off one side of the cylinder after being holstered. Externally there is very little if any surface rust (light). However after removing the grips the inside of the frame has what appears to be surface rust (no observably pitting). Prefer not to try and remove the sideplate. I have read that soaking the entire revolver in ATF or Kroll Oil will dissolve the surface rust. I assume if this indeed works that it would then require spraying with something like Gun Scrubber and then oiled with something like Rem Oil. I would love to hear your ideas especially real world experience.

Thank you,
