Today I took my Pi out of it's case and saw that the A/V jack on my Raspberry Pi 2 has turned black. It looks like it has been oxidated or something. What could be the reason, and has anyone else experienced this?

I can’t really tell from the photo, but if you are wondering why the metal finger is discolored: try rubbing it with a cotton swab dampened with alcohol. If something dark transfers to the cotton swab, then that finger was probably exposed to water at some point.
