Brasso is a fine polish, but it does contain ammonia. Some folks really hate the idea of using ammonia based polish on brass cases.
The stories of embrittlement of brass in an ammonia-rich environment is called "season cracking" and has to do with the storage of brass-cased ammuniton above stables in wet weather in India during the late-19th and early-20th Centuries.

If you consult the MSDS on Brasso, you will see that the concentrration of ammonia is not the same as a 19th Century British stable during a summer during the Raj, nor is the time of exposure in any way comparable (i.e. minutes versus months).
