Expiration dates remind me of an almost used up bottle of Crystal Hot Sauce that I inherited from my Bro-in-Law when they moved out of state in the late 90s – It has no use by date and doesn’t have a UPC on it either.
You can save Crystal till you go to your grave. It will discolor and loose some potency but is usable. Usually, A bottle doesn’t last long around my house![;)][:p][:D][8D]
