Frankford Arsenal Treated Walnut Hull Brass Cleaning Media – 5 lbs

If you reload, your brass is your most expensive component—and it deserves care. The Frankford Arsenal Treated Walnut Hull Brass Cleaning Media is a 5-pound batch of tumbling media designed to restore dirty, fired cases to like-new condition in a vibratory tumbler. Walnut-based media works by abrading away powder residue, primer residue, and carbon buildup without the mess or cost of wet cleaning, and the treated composition is engineered specifically for this job.

Why clean brass at all? Because what's on the outside of your cases doesn't stay there. Grit and fouling trapped on case bodies get dragged into your sizing dies during processing, gradually scratching and damaging their inner surfaces—which then marks every case that follows. Over time, that accelerates die wear and costs you accuracy and consistency. The same debris, if it makes it into your firearm, speeds wear in the chamber and feed system. A tumbler load of this media takes minutes of your time and eliminates all that downstream trouble.

Frankford Arsenal's treated walnut media is formulated to work in standard vibratory tumblers—the economical, hands-off approach most serious reloaders use. One 5-pound batch will handle multiple cleaning cycles before it needs replacement. It's the smart first step in the brass prep sequence, whether you're prepping pistol brass for a progressive press or rifle cases for precision long-range work.

Frequently Asked Questions

What tumbler does this media work with?

This treated walnut media is designed for vibratory case tumblers—the rotary-motion machines that are standard in most reloading shops.

How long will 5 pounds of media last?

That depends on volume and how dirty your brass is. One 5-pound batch will handle multiple cleaning runs before it becomes too fine or contaminated to be effective. Keep it in a sealed container between uses.

Will this media damage my brass?

No. Treated walnut is specifically formulated for safe brass cleaning. The abrading action is gentle enough to polish cases without pitting or excessive wear—far gentler than the environment of firing in a chamber.

Can I use this for both rifle and pistol brass?

Yes. This media works on any fired brass cases you run through a vibratory tumbler, whether pistol or rifle.
