Brass does not NEED to be washed (except with blackpowder cartridges!) and drying it thoroughly is a hassle and/or a waste of time. If you insist on pretty, shiny brass, then you leave it in the tumbler longer, and add a little Nu Finish car polish to the medium. Otherwise, when the outsides are clean, the brass is done, and is ready immediately to be deprimed, resized, and reloaded.Tumblers are fairly cheap, work well, and just don't have significant downsides. Why are we trying to reinvent the wheel?
Firstly, have we made the point strongly enough that washing brass is a waste of time & energy?? Get a tumbler and be done with it. Secondly, why deprime before cleaning?? It adds another step to an already necessary-but-no-fun process. You tumble the brass clean. Then you resize/deprime. Then you proceed from there. End of story.I hear that you should deprime before washing.
Go to Pets-Mart and buy a bag of "Lizard litter", its ground walnut shells, then go to an auto store and buy some Turtle Wax polishing compound. Pour your tumbler bowl about 1/2 full of ground shell, turn the tumbler on, and squirt about 3-4 tablespoons of the polishing compound in and let it tumble for about 10 min, make sure its blended in with the shells, toss your cases in and let'er rip! Then get a small paper clip to maybe clean the primer pocket and primer hole clear. Makes the cases look a lot better than factory!
