Once upon a time I belonged to a car site. The dreaded thread there was brands of oil. A mere mention would be biblical....40 days and 40 nights of comments! Anyway, here's my brass cleaning hint and any comments would be helpful. I'm a real stickler for clean brass. My local range is insistent on the shooters picking up spent brass. It's usually swept up and left in buckets and I frequently come home with it 4 inches deep in my range bag. After years and multiple trials using different cleaners, I've found that after washing in the usual water/dish detergent to remove the surface crud, a soak in a very mild solution of Klean Strip Concrete and Metal Prep and water leaves the brass mirror-shiny! If I've deprimed first, the pockets, as well as the insides are also clean. I buy this solution from Home Depot for about $13 per gallon and one lasts over a year. The diluted solution is reusable multiple times. Klean Strip contains phosphoric acid so the usual cautions should be observed. Anyone have a better idea or found another cleaner?
