Thanks for the tips, it was actually really easy to clean. I kind of did a halfway maintenance cleanup, got the threads polished up nice, wiped off the top of the ceramic bowl, and cleaned out the mouthpieces. Took a couple swabs of the bowl residue and put them back on top of the coil, not the tastiest but provided half a dozen more hits. Took 15 minutes, 2 q-tips, and a small dish of 90%+ isopropyl. What I realized is that concentrate will mostly move outwards from the coil, so there is no need to worry about iso somehow seeping in (if you do what I did and just clean the outer threading etc). Wipes clean without water.
I'll have to be more careful about overloading the Dabbler, I kind of wanted to see how far it could go. Even still that was really easy cleanup and I bet I could do a few more of those before having to actually clean the coil.
