Hi all. I wanted to hear your experiences with using Brasso to clean brass in a tumbler. An old timer who has been commercially reloading for decades taught me to do that, and it does make brass look great and knocks down some dust. I have read about ammonia damaging the brass, but I wonder if it is a real concern considering the brass doesn't last forever anyway.

I'm not trying to stir up a controversy, but I just want to hear about experiences to decide whether to continue using it. Can anyone share an experience where they have personally witnessed Brasso shortening the life of their brass or making it crack or something?

Thanks,
Greg
