I've been using isopropyl alcohol and it works great and dries off very fast. Many here do not seem to recommend it, but I'm comfortable with it. I've read the MSDS, seen it used in the medical industry, and used it for a multitude of things my entire life. Whatever molecules remain in my wick after air drying to completion do not concern me. It's much cheaper than vodka, dries more quickly, cleans all flavor out of the device, and I always have some in the house.
