Thanks very much, I was gonna start upping it a notch on each bowl this evening, but that's saved me some bud.
Working very well on that with a little fine tuning on the airports to be done.
ISO isn't actually that great at cleaning if it's really bad or gunked up in my experience, get one of those white 'magic sponges' used for cleaning, stuff that into the bowl
after you've cleaned it with ISO, you'll be amazed at how much crap is still in it.
If mine ends up really gunked, or has a whiff that won't go away, it gets a quick scrub and clean in ISO to get the easy stuff off, then dunked and left in a jar of sugar soap, leave it in that for 30 mins, I can see the brown stuff floating about that's been lifted off the metalware when I go back to it....
Thin bottle brushes and those magic sponges or a cheap alternative, they'll bring it all back up to an amazing shine with sugar soap, or like mine, it shows up every single tiny scratch and mark....

Spent more time with the 2 this evening, using low strength meds....
Starting to find a spot with the settings where I've reduced the irritation a bit when using the stem.
The head is open a crack, and the stem is open at the small notch, and a little of the bigger hole too. Brenyo suggested 340c° using the glass adapter, so I ran it till auto shut off, all of this worked really well.
Feeling happier about the stem now.
