OK, some great info here.
I agree re: resin. I tried getting 91+% last night and the local pharm was sold out. I'll try again tonight. I did use the alcohol wipe included with the kit, but sounds like that's a no-go.
I don't have dental brushes yet. I had them in my hand, but put them back when I couldn't find the alcohol on the shelf. I'll buy those tonight too.
Tell me more about the screen position, since that was mentioned by a couple of different people. How is it supposed to lean? Like, if I'm looking at it with the LED towards me, is it left, right, front, or back higher?
I did pop it out when I cleaned the Pax.When I put it back I noticed it would not fit straight in, and basically poked it down with my pinkie finger and the oven lid. I don't know that it's leaning at this point so much as slightly bent up at each side, and may indeed be covering the hole.
That said, I was having draw issues before that, but they certainly didn't get better when I replaced. However, I can draw basically OK with the oven door off and no product in, though, which led me to believe that the screen, mouthpiece, draw tube, etc. was unlikely to be the issue.
It's also entirely possible the resistance isn't significantly worse, but that I'm just getting much less vapor. It was a pretty slow draw fresh out of the box, but the big clouds would have gone a long way towards reducing how much I noticed that.
I'll try another clean tonight with hi-test iso and dental brushes and we'll see how it goes.
