I think your biggest issue won't be the ETOH, actually, but the stickiness of the yeast and sugars in beer. You did the right thing in removing the cartridge and letting it alone. I'd say wipe it down as best you can, and then either let it air dry if you are not living in a moist environment, or maybe even use a blowdryer on a low setting to make sure it's completely dry. The battery compartment should be sealed, so I'm doubtful that it's going to be a huge problem or blow up in your face, though that's never outside the realm of possibility. Is this a mod you can fire, or do you activate it by inhale only? I can't remember with the cartos as I don't use them. If you're able to fire the mod without having it near your face, I'd try that first. I am thinking that the worst that may happen is that your
device is toast.
With that said, I am a random person on the internet, and I don't own your
device. If you are truly hesitant about it, you could clean it up as best you can and bring it to a B&M with (hopefully) some knowledgeable employees who can take a look at it for you and note any warning signs. I simply say that because I understand your caution, and I too share it and I'd hate to recommend something definitively one way or another without knowing or seeing the
device, KWIM?
