How Long Do Condiments Last After Opening?
Published 2026-10-30
Most refrigerators have a door full of half-used bottles, and it is not always clear which ones need to be refrigerated or how long they stay good. Unopened condiments are usually shelf-stable until the best-by date, but once opened, storage matters for quality and safety. This guide gives general guidance; always follow the storage directions and dates printed on each product's label, which are the best source for that specific bottle.
Usually refrigerate after opening
Mayonnaise, mayo-like dressings, creamy dressings like ranch, blue cheese and honey mustard, and jarred salsa should be refrigerated once opened, and most labels say so. Ketchup, BBQ sauce, teriyaki sauce and steak sauce are commonly labeled refrigerate after opening as well, to keep flavor and quality. Keep creamy items cold and do not leave them out for long periods at parties.
Often fine in the pantry
Many vinegar-based hot sauces, soy sauce and Worcestershire sauce are high in salt or acid and are often stored in the pantry, although refrigeration can keep their color and flavor fresher for longer. Mustard is acidic and keeps well, but many labels still recommend the fridge for best quality. When in doubt, refrigerate.
Signs it is time to toss it
Throw a condiment away if you see mold, notice a sour or off smell, see separation that will not stir back together in a creamy product, or if the color has changed dramatically. Bulging lids or fizzing in non-carbonated products are also warning signs. Using clean spoons and wiping caps helps everything last longer.
Buy the right size
Large bottles save money per ounce, but only if you finish them while they still taste good. Big households, cookout hosts and heavy users benefit from value sizes, while smaller households may be better off with regular bottles. Writing the opening date on the cap with a marker makes it easy to keep track.
Organize the fridge door
The fridge door is the warmest part of the refrigerator, which makes it fine for most acidic condiments like ketchup, mustard and hot sauce. Keep creamy items such as mayo and ranch on a main shelf if your fridge door gets warm.
