Ok, so before my grandma passed away she gave me her wedding cake topper from her wedding back in '49. It is incredibly meaningful to me to use this as my wedding cake topper. However, it is metal. Pretty tarnished/dirty/ect which ever you choose to describe it. It is in great condition, but really needs restoring/polishing. Does anyone have any ideas/suggestions on where I can take this to be restored or how I can do this?
