Truck driver 2 is correct . this is what I do If I want factory looking brass, I do it in two stages one small vibratory tumbler with ground walnut shells I buy from the local pet store (used for bird bedding cheaper than gun brands of ground walnut shells) I will add a golf ball sized handfull of Bar Keepers Friend cleaner very fine scouring powder get it at walmart , RCBS also sells scouring powder in small packets does the same thing for a higher price. The down side this system leaves very fine scratches in the brass , but it also takes most tarnish off. I leave it run all night in the garage, the next step is to take commercial tumbling media from Hornady (ground corn cob) for a final polishing, all night again and it does polish out the very fine scratches from the first step. If it some picked up range brass and in really tarnished/ patina I will soak the brass in 50/50 white vinegar/distilled water solution over night let it dry and goto my first step and see if it comes out, sometimes yes and sometimes no, that tarnished you probably not going to use anyway. Another thing you can do is just use ground walnut shell polish with nothing in it and add a golfball size liquid Turtle wax and run it into ground walnut shell until it is dried into the walnut shells. I kind of makes the brass a little slicker/smoother good for semi-autos. if you put any liquids like turtle wax in tumbler and immediately put in the brass you end up with globs of turtle wax that get's into the casings and a mess to clean out. Got to run the liquid till it's dry before putting in any brass. One thing you never ever do is tumble or Vibratory any live ammo because it breaks down the powder inside and causes the powder to act differently i.e. possibly make it act like a hotter powder, just food for thought. Nothing ammonia based for cleaning ammo brass it reacts with the brass. If you have a spare 1/4 to 1/2 horse power electric motor laying around you can make a giant vibratory tumbler just find an old clothes washer or drier take the tub out, plug the holes , lay it flat, make a wooden or metal frame for the tub to sit on flat add a few heavy springs with bolts to secure the tub to the frame , then get a 1/4 x 2" by 6 " long piece of steel or whatever is on hand and drill a hole in one end to bolt it extra securely to the motor shaft and bolt the motor underneath the frame to make it shake out of balance causing the tumbler to vibrate. basically just like a normal vibratory tumbler just giant sized. I suppose you could just use an old 55 gal drum cut it in half and do the same thing. cleans a lot of brass real fast. This stuff is for people who have access to large amounts of brass maybe shooting ranges and alike.
