Like many others I no longer use the pins. I tumble using a half teaspoon of citric acid and good squirt morning fresh lemon dishwasher (I’ve tried all the Brands and this works best) Also you must use HOT water. I tumble in a Frankfort Arsenal tumbler for between 15-30 min & then rinse clean and dry by putting in a towel sock before putting on trays in the sun.
Works a great
