Christopher,
If they were my doors I would remove just the patination by buffing and
using cutting compounds. Buff entire surface with a rouge, wax and polish.
Rewax two coats of Microcrystalline Wax yearly. Or apply hot patinas to get
an even blue/green and then wax.
If they were a client's doors I would recommend they contact a
conservator that does historic bronze doors all the time and can suggest a
myriad of options, finishes and annual maintenance required, including
estimates of cost. One such person is Franicis Miller of ConservArt LLC. A
new member of The Guild of Fine Craftsmen and Artisans: 203-248-2530
Best,
Leland
