Cleaning vintage Tins?
I have a question about a new collectable I have suddenly developed an interest in, vintage tins. I have aquired a few and now I am wondering how to clean them? Some I would like to use, storage of trinkets, etc. but some I will use only for display. What is the best way to clean them? A few are grimey, in and out so I imagine I need some type of non abrasive agent/cleaner with a soft cloth to remove surface dirt. For the ones I will be using only for display can I give them a light buff with some J&J wax, or the like? These are NOT advertising tins, just decorative. Some need nothing at all, but some are in sad, but savagable shape.
Any advice would be greatly appreciated.
