Since you're going to start Reloading and you have a ton of old Brass , buy a high capacity vibratory Tumbler and get started . Buy some Commercial Tumbling Media , add some Commercial Cleaner devoid of any Ammonia like Midways and/or something like Soft Scrub from your local Grocery Store and in 1-2 hours ...maybe a little longer , and I think you will have nice shiny Brass . The previous Post about annealing old Brass was good , but that's a whole nuther story .
