As an idiot, I always had a slight issue with using sanitising solutions (non-sulfite) in airlocks. On a few occasions
I have suffered backdraft (due to removal of a 'rubber boot' based airlock and in placing large soft rubber bungs into
the carboy). I.E. A few times there has been fluid sucked back through the airlock which has ended up in the wine. I
haven't had the airlocks too full as far as I can make out, but I am pretty sure a little fluid has made its way in
there. If it hadn't been a mild sulfite solution I had in there, but a more general solution I would have veritably
lost my composure at potential reactions (though the wine just shrugged and got on with it).
