First off let me say that I use both ways of cleaning my brass. Vib and Wet. I have also heard arguments from both sides saying theirs is best. I do one way or the other depending on how I feel that day.
My question is:
If you dry vib, do you add anything to the walnut shells?
BTW if you use walnut shells, go to your local pet store, not some big corporation box store. I have found that the smaller store 's walnut shells have a LOT LESS DUST!
