So I cleaned some brass for the first time in a ultrasonic cleaner. This unit also has a heater so I turned up the heat. I used the Hornady solution at 1/2 oz per 20 ounces of water. Now this was my first time using the ultrasonic so I was pleasantly surprised by how nice it turned out. What puzzled me though was a few pieces of the brass (.223 stuff) looks pink! Anyone ever get pink brass after using a ultrasonic? IS it defective? Besides the Hornady one shot juice, what is everyone else using? Thanks!
