Brass oxidizes, and the surface will look black. The oxidation wipes off with a tissue due to the mild abrasive nature of paper. If what comes off has a green hue to it, it's an oxide of copper (present in brass) and possibly of zinc, also part of the brass alloy.

If I had juice turning black on my battery threads, I'd be questioning my use of that juice.

Just ask anyone that has gold plated brass jewellry about the greenish black that appears on the skin
