They have built up over a few years, the toe print in the photo could have been from when it was originally done, there it a back corner I could experiment with, and I am thinking of trying some of Johnson's wax on it

I have a copper shingle wall that is starting to show fingerprints. It has a brown to black patina on it. I did not do the original work so I do not know what was used for the patina. I am guessing the answer is no but does any one know of a way to clean the oil/finger prints off without striping the patina?

And what one could use to get a similar finish in case I do have to strip and re-patina?
