Oy. What a sad thing to happen to a mod. I'd junk the
batteries personally, or at least tend to them lovingly while they charged, then maybe use the leafblower solution (it's on another thread, I forget) to fill your
tank with
juice and empty it out fast to be sure your batteries don't explode and that might be the FIRST way I'd clean the atty, also. Then, I'd clean the parts I can, maybe with some hydrogen peroxide or alcohol, and let it sit for a day. Then, I'd find a new driptip. If your mod is fine, I'd probably clean it off after reassembly with the same kind of stuff, like wipe it down with an alcohol pad (the exterior, at least), so that I could feel remotely okay about using it.
I understand your desire to not want to junk what you don't have to, regardless how horrific the situation.....
My kid dropped his phone in the toilet, we undertook similar measures (rice doesn't work, I'm a big fan of the blowdryer) and cleaned it off in a similar fashion, but thank God it was at *home*.
I wish you all the luck in the world with this, and if you can get over the ick factor and it's working? Well, good for you.
