In the military we polish brass that we wear not shoot. Brasso does a good job on it but isn't used on any brass that goes into a weapon.
There's plenty of polishes out there that don't contain ammonia.

The ammonia contact is bad for brass over time. We had a member who polished a bunch of ammo on machinegun belts with Brasso that he had on the wall of his room as a teenager. It was all put in a trunk when he left home, and he didn't see it again for 20 years when he pulled the trunk out for a look at his old things. He said the cases were badly corroded and enough were eaten through that powder was spilled all over.
The type of damage caused is the same as what is called "season cracking". The Wikipedia article on the subject describes it well enough.
Other brass, like buckles, don't have a problem because it isn't under great stress. You'll note season cracking usually starts at a case mouth and neck, and that's because of the stress from being stretched over a bullet. But if the brass is work-hardened, like the lower part of a case, eventually that stress will crack the brass, too, if it has been weakened by ammonia.

A long time ago when I first started reloading I used brasso on my brass. Never did any harm to cases I fired over the season as by the end of this season I'd throw them away.
Now, brass that I loaded and stored was another story. When I tried shooting the stored ammo every one of them had neck cracks.
I won't use anything ammonia on cases anymore. Couple years ago I had a group tell me I was nuts and that they use it all the time. To each his own, but I won't use it.

One capful of "NU Finish" automotive polish added to your media will do the job.
