The red is jewelers rouge, iron oxide, AKA rusted iron. Once it is used and dirty, no.
Just for the heck of it I added a sort of light jeweler's/silverware polish some time back. I really couldn't say if it improved things but my brass came out with a matte finish! I was annoyed by that. But when I would resize the cases the matte finish would turn shiny. Hmmm. But it was intermittent and I tossed that mix.
I also tried some larger grit walnut shells and they worked but the larger grit clogged the primer pocket!

Now I'm using corn cob but I have some used lapidary ceramic polishing stones (rounded from wear...) and I might try dropping a couple of them in to see what happens.
