Dillon Brass Polish 290 | 8 oz

Rapid Polish 290 makes your tumbling media work harder. A few capfuls poured into the media cuts through fouling and powder residue, leaving brass bright, dry, and ready to run straight into the press — no rinsing required. It's formulated to clean without weakening case structure, and cleaner brass means less abrasive buildup in your dies and machine. Works with Dillon walnut or corn cob media, or most any dry media you've already got.
