If you reload rifle or handgun ammunition, keeping your brass clean is one of the simplest investments you can make in die longevity and round consistency. Frankford Arsenal Treated Walnut Media is a 5-pound polishing media designed to work in your brass tumbler, removing primer residue, carbon, and tarnish from spent casings before you begin the sizing and reloading process. Walnut-based media works by gentle abrasion, and this treated version includes built-in brass polish to enhance the cleaning action—your cases come out visibly brighter and ready for the next reload cycle.
Why does clean brass matter? Grit and carbon trapped in uncleaned casings get pressed into your sizing dies, gradually scratching and degrading their surfaces. Over time, that wear translates into dimensional inconsistency in your finished rounds. The same contamination also accelerates wear on your firearm's chamber and feed system. A few minutes tumbling your brass—whether fired once or a dozen times—costs far less than replacing reloading dies or dealing with chamber erosion.
Treated walnut media strikes a practical balance: walnut cleans more aggressively than corn media, so you spend less time per batch, and the integrated polish gives you a professional finish without a separate polishing step. This is the economical, efficient first step in any reloading sequence for shooters who demand clean, consistent ammunition.

| Category | Case Cleaning & Preparation |
Walnut media cleans more aggressively than corn, so you need less tumbling time to remove carbon and primer residue. Corn media polishes brass more effectively but requires longer run times to achieve similar cleaning results. This treated walnut formula combines both benefits—faster cleaning with built-in polish.
No. The same media can be used multiple times. Over many cycles, it will gradually break down and lose effectiveness, but 5 pounds will handle many batches of brass before replacement becomes necessary.
This 5-pound package is designed for standard brass tumblers. Check your tumbler's capacity to ensure it can accommodate this volume—most popular rotary tumblers accept it, but verify your specific model's guidelines.
This product is formulated for dry tumbling. Always follow the tumbler and media manufacturer's instructions for your specific cleaning setup.
