I use citric acid, in the form of a product available at Wal-Mart called "Lemi-Shine." It takes around 20-30 minutes in warm water to clean up normally soiled / tarnished cases. Cases should be deprimed first. Extremely bad corrosion will probably have to be dealt with using steel wool. Avoid any brass cleaner containing ammonia, as it weakens the brass.
If you want factory-shiny cases, tumble (I use the vibratory kind I've had forever) in corncobs. I use a product called NuFinish (available at finer auto supply stores everywhere) to do the polishing. Not necessary, but it produces a pretty case.

Just do not use any brass cleaning products or auto polish. Most of them contain pumicite, ground up pumice stone (the stone you use to remove skin on feet). Very abrasive.

The way I clean cases is so in depth that most folks wouldn't spend the time that I do.
But for me, it's just what I do. A clean case is a happy case...(easier to spot defects as well)
And I agree with being careful on what you use, as stated, some chemicals can weaken brass to the point that it could be dangerous.

I do a similar thing but with some variations. I don't use the acid. That removes oxidation which I don't mind. My objective is clean cases, not ones looking like they were made yesterday. I use hot water because it cleans better and I add the detergent as needed. I first rinse in hot water to warm the cases, drain that, and then wash and rinse twice with hot soapy water. My well-water has lots of minerals so I do a final rinse in distilled water from a dehumidifier. I guess rain or melted snow might work too. My dehumidifier also blows warm dry air over my cases to finish quickly. I sometimes use a hair-drier if I'm impatient. I inspect primer pockets and some interiors with a light to make sure no drop remains. I've been doing this since I started shooting in a sandy location. Sand gets into ejected cases. Even a ground-sheet gets contaminated with the stuff from coming and going. The hot water and detergent gets rid of my oily case-lube too. I too clean cases before resizing to be sure to remove sand and after resizing to remove oil and primer-residue. Cleanliness is next to doing things right.
