Eli, you're 100% right about Rich referring to the steam wand cleaner, but I think you're a bit confused on the teflon bit. The Vetrano (and all insulated steam wands) channel the steam inside the teflon tubing, which the tip actually seals around. So the inside of the steam want (the SS part) never gets exposed to steam or milk that is siphoned up into the wand if the pitcher isn't removed quickly after steaming milk and shutting off the steam—only the inside of the teflon tube would be exposed to this, so it's what you'd want to clean.
Which brings us to the gist of Rich's question, which is what the inner diameter of the teflon tubing in the Vetrano is. I honestly don't know, Rich, but having owned a Vetrano I can say from my vague recollection that I don't think it's anywhere near 7 mm, maybe more like 3-4 mm. Maybe a helpful Vetrano owner can confirm this? If you got it from Chris Coffee, you can probably call them and get a tech on the phone... takes all of 2 minutes for a guy with a set of calipers to check.
More generally, Rich, I would ask why you want a Steamy Wanda for the insulated wand? In any of the espresso machines I've owned I've never experienced the siphoning effect unless done on purpose with water. You really have to leave the pitcher there for a bit or actively cool the wand with a rag to get it to start sucking milk up there. Teflon is even less likely to do this, because it's so insulated and because it's... Teflon. I imagine it's a lot less likely to let scalded milk burn onto it.
