OK, lots of home made recipes to clean the outside of the necks to remove carbon etc before media cleaning. I've used Flitz and steel wool for years depending on my mood. So I was cleaning brass today and had both Flitz and steel wool on bench, Eureka! Now I know where Reeses PB Cup came from! I dropped a very small dab of Flitz on the steel wool and HOLY COW did it clean and polish at same time and instantly! I use a small Skil driver with a Lee shell holder to spin case while applying the steel wool and Flitz. No muss or fuss just brilliant shine! Now off to media cleaner to finish!
