I just got really confused. I was sorting some brass I had laying around and I noticed about %10 had this funny color. I looked almost like rust spots. This brass was resized and tumbled at some point and then it sat for about 2 months in an Akrobin in my garage. I have no idea if it looked this bad before. It is present on both S&B and Win brass. Others from the same bin are fine. Is this just some crud that the tumbler didnt clean? Is the brass no really brass and can actually rust? I have seen little green spots once in a while (and discarded) but this is new.
Any idea where this stuff is coming from? What is it? I hope the picture shows it clear enough.
