I was just reading about this a month or so ago, on one of those rabbit hole trips online.
No surprises, but things like ketchup, mustard, etc don't need to be refrigerated, but their shelf life is rather significantly increased if they are.
Ketchup, I don't go through it all that fast, so that can have some age on it, especially since I buy the big bottle of it. Mayonnaise, no problem there, as we do eat that quickly.
Mustard...we eat a lot of mustard, but we also have a lot of varieties, so it can take a while to get through a single jar of it.
