Iosso Case Polish - 32 oz (1 quart)

Iosso Case Polish brings your brass back to life with a straightforward tumble-media additive that cleans and restores fired casings to a high shine. Whether you're prepping brass for a precision reload or just want your ammunition to look as clean as it performs, this 32 oz bottle treats enough media to handle serious batch work. It removes powder fouling, oxidation, and tarnish in one step—and keeps your cases from discoloring again between sessions.

The formula is built on USDA-certified bio-based ingredients with no petroleum distillates, no harsh odor, and no volatile organic compounds (VOCs). That means you can work in your reloading space without the chemical headache or lingering fumes that come with older polishing compounds. It works equally well on untreated media or media you've already processed with Iosso Case Cleaner, making it flexible enough to fit your existing brass-prep routine.

Application is simple: add two tablespoons per pound of untreated media, or one tablespoon per pound of pretreated media, then tumble for about an hour. Heavily tarnished or dirty brass may need more time in the tumbler, but the chemistry does the work for you. A single quart covers substantial case volumes, so it's economical for handloaders who process brass regularly.
