Ok so I have cleaned a few batches of both 300WM and 308 using stainless steel media. I am having a problem on about half of what I have done, but I believe I have gone through the same procedure on all. The brass comes out of the black water very shinny but very quickly tarnishes very quickly. I first rince the brass with cool to cold water until the water is clear and no more suds. I then run warm (almost hot) water over them to make sure all the chemicals are gone and then fill the bucket back up with cold water and dump the media out of the brass. By the time I have the brass all cleaned out in the drying trey it has changed color and looks tarnished. What an i doing wrong?
