What about tabasco?
Tabasco is perfectly safe outside. After all, it's just vinegar and peppers. But once opened, it will change color and get darker after a while. No change in flavor, but it's not very appetizing compared to the fresh color. Huy Fong Sriracha Chilli Sauce (the one with the rooster - very useful for putting off those who order just a spring roll and then want to filch off your pad Thai) is the same, except that, even with preservatives, as well as vinegar and salt, it darkens more rapidly, even when it doesn't get much chance to hang around long. I'd refrigerate that one, if you don't use it nearly every day.
