I read that same thing too. I'm still learning when it comes to the different metals.My Ultem arcs but I figured that was typical of silver contacts but I'm new to this whole thing. I just clean with q tip and rubbing alcohol. But didn't know Ultem version had pure silver vs plated. I guess with pure the arcing is conductive I read earlier? Still I clean it regardless.
I don't want to put no ox id somewhere that close to a squonk bottle to help prevent arcing lol. Maybe I'm being paranoid but that sounds like cancer to me if I over did it like my clumsy ass usually does and some got its way into my vape.
