Old colt cleanup the grip medallions

[Rubberduckie]

I inherited my grandfathers colt revolver he carried while on Detroit police department. The medallions on the grips have a green oxidization on them. How can I clean them up without hurting the grips? I can post a picture later today if that helps.

I believe that the medallions can be removed after you remove the grips from the pistol. Use a metal polish or brasso to polish them.
