BUFF7MM

I’m wondering what those of you who wet tumble do with your nickel cases. The reason I ask is I just started wet tumbling with SS pins, Lemi Shine, and Dawn dish liquid, and use a Thumblers Tumbler Model B. I ran some 10mm cases of both brass and nickel together for about an hour and a half, when I took the cases out they looked dirty and dull. Now when I ran just brass cases I didn’t get the dull and dirty problem the cases looked like perfect new cases.
I can take a rag and the nickel cases will polish back to shiny but the brass cases remain dull but clean. Does anybody have an idea what might be happening? It seems that different headstamp nickel cases came out differently also, the Sig cases were bright, Federal and Winchester were so so, and the Speer cases were the dullest and dirtiest. I know it won’t make a bit of difference in loading them but I’m pretty sure I’ll stay away from wet tumbling the Nickel cases unless I can figure out how to keep them from tarnishing.
On the left are the repolished cases, the right are just tumbled.
