Vintage Coach, deoxidizing?

[rosacalifornica]

I'm looking to buy a vintage Coach bag from an online seller, but this picture of the zipper (attached) worries me. The threads have gone green from what I believe is the brass oxidizing. Is there any way of repairing this without taking out the zipper entirely?

Thanks so much for your help!

The technical name for that green color formed by oxidized brass is "verdigris" and it's a common problem on vintage Coaches.

Interesting I have some Coach vintage bags and none of them have that

I have had luck with removing verdigris with Tarnex, available inmost grocery stores. It's great to use on brass zippers because it does not stain the zipper cloth. I think it is there because some one used a brass cleaner on it and it left the residue. You can also try ammonia.
