I clean my brass by tumbling in an old rock tumbler with plain uncooked (not instant) medium grain white rice, and a tiny flick of Mother’s Mag & Aluminum polish. It does a really good job of cleaning the outsides of my cases, but it leaves the insides of my fired brass pretty much uncleaned. I keep my flash holes clean, and I have some .38 special cases that have been reloaded 10+ times with no “obvious” effects to rice cleaning. Is it necessary or advisable to clean the inside the cases?
