thanks for the comments on thew Lemishine... I have lots of citric acid where I work... will likely use that...

anyone know if there is an acid level where the brass starts getting brittle ???

I think I had heard that ammonia will make the brass brittle ( specifically if polishing compond was used with corn cob media, there were several cases where they thought the brass became brittle ??? )
