Yeah, I think there are a few saying that. Very nice s/u you have there. What is the topper on there, matches very well.

You could always try a WTB in the classies to get another Poldi.
Now I gotta go look that Gem RTA up.![]()
I went a little crazy when they went on sale. I just couldn't pass them up especially since early on during the sale they came with all three battery tubes. I believe later on during the sale it was for just single battery sizes. I bought the four models i wanted and then after adding up the price of all the spare parts i wanted, i found it a better deal to just buy four back ups. So yeah, i have 8 Poldis now and don't regret it at all. Four have only been opened for inspection and put away. If i ever decide to part with them i'll give you guys a heads up first.
That black discoloration is oxidation from the air. Oxidation begins again from the moment you cease polishing.
Poldiac owner's manual recommends baking soda for the contacts. Rice pins and screws in full button body assembly.
You answered your own questionBut, if it's oxidation, how come it's only in one thin little ring instead of the entire pin? And that ring seems to be right where it makes contact with the end screws.

The whole pin does oxidise. It's removable from the plastic button part (the trigger). You'll notice a black buildup on the plastic if your housing is beige. But oxidation buildup is more where the business ends of the rice pin are exposed, and completing the electrical circuit
Isn't Clabber Girl baking powder? It prolly wouldn't hurt it. Baking soda is like a few cents at the dollar store.Okay, I guess that makes sense, although I do notice it's only on one end of the pin, and that end is always the one that makes contact with the bottom of the switch, and it's always a distinct and very thin black ring. I've been quite curious about this. It seems to me it has to do with current at the point of contact. I take the pins out of the button housing and clean them with alcohol, but maybe the baking soda is a better way. Can I use Clabber Girl, or must it be Arm & Hammer?

It took me, seriously--half a day to dismantle and clean those mods. Not the assembly--just scrubbing them down. My Poldiacs still work, tho.
I would maybe not use chloroform to clean your contacts. Fumes are toxic.
