Reconditioning prime agra???
Does anyone have a method of cleansing/purifying old prime agra so that it can be reused?
I have been soaking it in clorox and water for few days, then completely drying it in the sun, before baking it at 400 degrees for a few hours, to kill anything living, I hope.
Then I have been soaking it in magnesium sulfate---or another time, vinegar---trying to get out any dissolved minerals. Then soaking in fresh water for a few more days.
Anyone have a method with more "science" to it?
