If you are going to go the route of wet cleaning use white vinegar, and dish soap. Put some in a large gatorade bottle with the brass, shake for a bit then let is soak for a few minutes, dump it out, put in fresh water. Recap shake, dump water. You may have to rinse more than one time. Then let the brass dry. You are good to go. I you want super shiny brass after loading use a Lee shell holder, and drill and some 0000 steel wool it will shine it up in a couple of seconds. The wipe off with a dry clean patch. Voila.

Or you can use a tumbler with some newfinish car polish and walnut media. I run mine till it is clean, does not have to be super shiny. Rifle brass gets another run in the tumbler to remove case lube it usualy comes out pretty shiny after that.
