Figuring out whether that ketchup bottle in your fridge is still good can be tricky. Sure, it may look good, but you actually won’t know for sure until you try it. If there are no obvious signs of spoilage on your condiments and you are still unsure whether they are good or not, it is best to use some common rules about their shelf life.


A bottle of ketchup is expected to remain good for up to six months after opening. This is under the assumption that you’ve kept it in the fridge.


You shouldn’t let mayo sit in the fridge for too long as it spoils faster compared to other condiments—because it’s made from eggs. When you open a jar of mayonnaise, you can expect it to be good for just two months when kept in the fridge.


Mustard, on the other hand, is much more durable. Once you’ve opened the package, it shouldn’t spoil for up to one year.

Soy Sauce

Soy sauce will remain good for a couple of years if you don’t open it. However, once opened, it should be used for one month. You can tell by smell if it’s started to go bad.

Barbecue Sauce

Barbecue sauce will last up to four months in your fridge when opened. So buy one at the beginning of the summer, and you can use it throughout the entire season.

Hot Sauces

Hot sauces can have different shelf life depending on the ingredients they use. However, the general rule is that they will stay good for six months when refrigerated.
