Patina Everything! vinegar, white or apple cider salt, just regular old salt out of my shaker. For small items. I fill a quart yogurt container half full of vinegar, and sprinkle in some salt. (not measured, but guess 1 tsp.??) dump your keys, clips, hinges, watch parts, locks... any metal you want to 'age'. I leave them over night, just 'cause it is convenient. Seal if you touch items a lot
