For years I used my wife's dishwasher (with careful planning.) to wash my brass in small mesh bags . It cleaned but the brass was still ugly and needed extra attention to assure there was no residual water. Not ideal at all.
Then 20 or so years ago, I started reloading enough to warrent a better solution. After some research I bought a house brand vibrator from Midway. I've played around with different medias and polish's in that time (mostly due to availability) but have long since settled on crushed walnut shells and NuFinish 2000 polish. ( Throwing in a dryer sheet every now and then if range brass is especially raunchy.) Every batch comes out clean and shiny with little effort. Can't see any reason to "upgrade".
