I had a pistol match last month and came home with about 300-400 rounds of mud coated brass for me to reload.. Looking at this mess, decided to water and soap clean them first. So, I threw all the brass in a bucket hosed it down to get rid of the mud and grass. Then let them soak in the water with some dawn dishwashing soap and every once in a while for the next 3 days, I swirled the mixture with my hands. I then rinsed the brass off and dried them. I was pretty surprised to find the brass all clean and shiney and thought they looked better then I ever saw coming out of my case cleaner filled with walnut shells. But I threw them in there any ways because Im old and this is what I have been doing for the past almost 40 years.. Took them out of the case cleaner and they look dull and almost dirty and this is with almost new media ? I think Im done with the dry media and will just use my bucket with dish soap from now on unless some out there can convince me otherwise..
