FWIW, I use Lemishine by the hour without a problem. My brass are mostly Starline, with some Winchesters in a few calibers. Recently ran out of LemiShine and switched to a strong teaspoon of Wood Bleach (oxalic acid). Never got the reddish brass.
I am absolutely certain that you have MUCH more experience than I when it come to cleaning brass with a wet tumbler (I have only had one for a few months) and my conclusions about the lemishine are preliminary. I have done quite a bit of online research on using the wet tumbler and have found anecdotal evidence such as yours that lemishine works great. That is why I bought some. I have also seen MANY anecdotal reports that it draws out zinc and turns brass reddish. Of course there are MANY variables, such as how much lemishine is used, haw much brass is being tumbled per load, what else is used with the lemishine and, of course, cleaning smokeless shells is not wxacley the same thing as cleaning black powder shells. My conclusions (so far) about lemishine is based on very limited tests and I may try out again but my last batch of BP brass without lemishine came out MUCH brighter and shinier and yellower than the previous batch done the same but with the addition of lemishine. Jury is still out for me but the testing will continue. Thanks for sharing your experience with lemishine.
