Bottle Refrigerator Is It Necessary To Put Bottle Of Ketchup Or Sauce In The Refrigerator?

Is it necessary to put bottle of ketchup or sauce in the refrigerator? - bottle refrigerator

I live in a warm place and asked me if I cool the sauce or peanut butter in the fridge.

What cool things can then feed others? I am referring to food in bottles or cans.

All proposals will be of benefit.
