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! It took way too long to manually unclog the pockets so THAT got tossed. too.
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.
