I use corn cob media. I have 2 batches. One is for cleaning and the other is for polishing. To clean a load of dirty brass I run my tumbler about 1 hour. Polishing is a 3 hour run.
When the cleaning batch gets almost black I will wash it with a Tbsp of Dawn dish washing liquid. I will agitate it a couple of times over a 24 hr period to get the dirt to break loose. Then I will rinse it until the rinse water goes clear. Then I dry it in the sun on an old tee shirt.
Once the cleaned corn cob media has dried I add a tablespoon of car polish and that becomes my polish batch. The previous polish batch becomes the cleaning batch until it goes dark and I start the cleaning process.
My media is about 2 years old and I see it lasting a couple more years. I wash a batch of media about every 3 to 4 months. I am cleaning and loading about 10K of brass per year. Everybody has their routine. I got turned onto washing the corn cob media by one of the older guys at the range.
