I also decap at the range and put the cases in soapy water, everybody seems to like Dawn, but I'm not sure there is a significant difference between dish soaps. When I get home, and it's an hour or more drive, so they get agitated somewhat, I pour off the water and rinse. They then go into my tumbler with 2mm ceramic beads, water, and more soap. After about an hour or two there I pull them out. They are clean, but not pretty. If I want them pretty, I tumble them in walnut media until pretty.
