I would be a bit wary of using an alcohol like Vodka as some brands add stuff to it and there is sugars which could gunk up the place a bit when they caramelise if you don't get it all off :(

The advantage of Isopropyl or its cousin surgical spirit/rubbing alcohol is they vent off cleanly when exposed to air and those cleaners are used in surgical and food preparation hygiene standards for cleaning of materials such as steel and plastic surfaces but of course boiling is still seen as an effective cleaning method today too so its really down to how far you really want to go with it imho.
