Can someone please help me understand why a load of brass that I tumbled turned out copper colored? I have attached pictures.
I have washed thousands of pieces of brass. my recipe is dawn dish soap, lemi-shine and water. Wet tumble for 2-3 hours.
You can see the difference between two sets of washed brass and a closeup of the dis-colored brass. It actually looks like the brass is copper.
