I was waxing my HS today and remembered I had a set of new, unused PINBALLIFE's Premium Ultra-Gloss Pinballs, figured now was a good time to put them in the pin (3 months in storage). I kept them in the individual ziplocks in the bigger ziplock in a pin and when I got them out they had lite surface rust in spots...damn it! Now they are in my tumbler with crushed walnut shell and NO additives (flitz or polish). What is the best way to store pinballs? What is the best way to refurbish pinballs? Any and all advice is welcomed, Thanks, Bill
