I have found that if they are really dirty and tarnished to soak them in vinegar for about a half hour. I then rinse and dry under a fan before I put them in the tumbler. After an hour in the tumbler with some Nufinish they are like new inside and out. Even the primer pocket is shiney. Just make sure to get all the vinegar off. I put a batch in the tumbler still wet and it turned the brass black.
