Wet tumbling with stainless steel media produces super clean brass, far cleaner than it is possible to achieve with dry tumbling methods. Even the primer pockets will be clean. It eliminates toxic dust that can be produced by dry tumbling. Since the media can be reused indefinitely, it's also far cheaper in the long run. Lyman stainless steel media pins are perfectly sized for the job and are supplied in a 5 pound package.
