Wow, had I had your experience I would have sold it and gone back to dry tumbling! My experience was simple: a 2 sec. squirt of Dawn, a .45 acp case full of lemishine in luke warm water. Four hours later bling. I use a media separator, rinsed once in cold water, and laid it in a beach towel on the floor....rolled it back and forth in the towel....stuck it in the kitchen oven at 120 degrees for 30 minutes....and that's it. I did NOT use vinegar....that's what the lemishine's for, and too much lemishine means pink brass. Picture in my first post was the result of my effort. Sorry you had such an ordeal.

No I did not INTENTIONALLY use vinegar, I followed the recipe, the vinegar was for initial cleaning out of the hot/cold water dispenser, as my water is ridiculously hard. There was just enough residual in it after i cleaned it to cause my problem. I am going to run another jug (5 gallons) through it before I use it again. LOL

Up there in post #3, I posted what I did copying others who supposedly "perfected" the process. I used cold water and no pre-clean with vinegar. Just a .45 case of Lemishine....more than than turns the brass pink....leaches copper. Lots of Dawn to handle hard water and that's it! I collated, then roll-dried the brass in a beach towel....then 30 minutes in a 120-degree oven....and I got nothing but bling....no spots at all. If I had had all the trouble you had, I'd have sold the thing and returned to corncob. You have a lot of patience....more than me.

And now...the rest of the story! I am no longer seeking a patent on the "penny coloring", as I tumbled the red brass in fine corn cob media the red coloring was nearly gone in about a half hour. There was just a hint of color left, but I couldn't differentiate between unfired, new factory brass that has been in the storage locker for a year or so, so that's not going to work. GWS Just to clear things up, I did not pre-clean the brass with Vinegar. I pre-cleaned the water cooler with it per the manufacturers instructions. I have extremely hard water, and no running water in my barn, therefore I purchased a hot/cold bottled water dispenser. Now that the vinegar has been completely flushed through the dispenser, and a little tweaking of the Dawn/Lemi-shine ratios, the brass is coming out looking like the above pictures, and overall I am very pleased with this system.
