Plus, you already have some star san made up (you've gotta sanitize the carboy/funnel/etc), so you can just reuse a couple ounces of it for the airlock.

This. How are you all getting suck back into your brew? I've never had that problem.

Cold crashing after fermentation is how it has happened to me. No big deal since I use irish whiskey. Used to use cheap vodka, but I like to take a shot after finishing a brew day and I did not like the vodka.

I usually use StarSan. I used to use vodka more often when I was using glass carboys since starsan made things slippery. Now that I've switched over to a PET carboy I've been able to retire the vodka to the liquor cabinet.
