🔧 How to Use (Best Practices):

1. Fill your tumbler with pins and brass, leaving space for proper tumbling.

2. Add clean, hot water (cold works, but hot improves cleaning speed).

3. Use ½ tablespoon of dish soap (like Dawn) per 1 lb of brass.

4. Tumble for 30–120 minutes, checking every 15 minutes initially.

5. Optional: Add dishwasher detergent powder (with citric acid) for extra shine.

6. Rinse and separate brass immediately after the cycle to prevent residue sticking.

For best drying results, towel off the brass, then air dry on trays for several days.

Whether you’re reloading spent casings or polishing small metal parts, this media delivers consistent, high-luster results every time.
