Don: there's one fly in this ointment. Air. When you use the valve dropper, air returns in, leaving a mixture of air and the suspected offender around the valve of the spout. I suspect you might wait a long time to see anything happen in the jar. Is there a way to expose the pins to air -- such as taping them near the top of the inside of the jar, then opening the lid a couple times a week to introduce the air that is necessary for oxidation?
