There is a balance between keeping the original patina and restoring. In most cases I favor leaving the patina where possible: however, I have a dilemma concerning the door plate.
The plate looks like it is probably brass. Over time it has become tarnished and is no longer legible. Also, there appears to be corrosion under the screw heads. Preventing further corrosion can be dealt with with by replacing the steel screws with stainless. But, I would like to see the details on the plate and have been considering polishing it.
Below is a picture in the current state and a couple of enhanced pictures to bring out the detail.
Please let me know what you think.
