How to Clean Rifle Brass Cases

Brass has become the overwhelming choice as the material to use for rifle cartridges. Brass is strong, durable, capable of withstanding reloads, and relatively cost effective to produce and sell. During the firing process, powder and bullet residue may accumulate on the neck and interior of the brass rifle casing. It is important to thoroughly clean as much residue as possible from the casing to prevent possible problems during or following the reloading process. Cleaning the brass can be accomplished by hand cleaning, chemical process, tumbling, and even in a washing machine.

Instructions

    • 1

      Visually inspect the brass prior to cleaning. Make sure there are no cracks in the neck or body of the brass. Also look for dents and misconfiguration to the shell casing which may interfere or affect the reload.

    • 2

      Completely submerge a number of casings in hot soapy water. Use a detergent such as Dawn or other similar detergent which features stain and grease lifting action. Allow the casings to soak for a period of time allowing the soap and hot water to loosen any residue.

    • 3

      Remove the casings one at a time and run the neck cleaning brush into the neck and body of the casing. The neck brush will typically feature a cone shaped spiral of stiff metal bristles. Insert the brush straight in and pull out at least two times to ensure the majority of the residue is removed.

    • 4

      Polish the outside of the casing with Magic Wading, a Scotchbrite pad, or fine steel wool. The polishing process not only helps improve the appearance of casings but also removes residue which may inhibit the reloading process. It is important for the casing to fit smoothly into the reloading die.

    • 5

      Thoroughly rinse the casing inside and out to remove all loosened debris or residue. Place the casing on a towel or slightly elevated metal grid to allow air to circulate around and into the casing for further drying. Repeat the steps for all brass casings to be cleaned.
