Do you love mayonnaise but hate the fact that it goes bad quickly in the fridge? Well, mayonnaise doesn’t last long in the fridge for everyone, but there are a few things you can do to extend its shelf life. 

In this article, we’ll outline all you need to know about mayonnaise and how it affects shelf life – from its different types to how long it takes to go bad.


Guide on Mayo Shelf Life

Mayonnaise is a staple in most homes and can be used in a variety of dishes. However, it’s important to know how long mayonnaise will last in the fridge before it goes bad. Mayo is a type of salad dressing made from eggs, vegetable oil, and vinegar. It’s often stored in the fridge to keep it fresh – however, it can go bad relatively quickly. 

If mayonnaise smells sour or has chunks in it, then it’s likely gone bad and should be thrown out. Mayo will last in the fridge for about two weeks if you make only a small amount each time you use it. So, make sure to store mayonnaise in a fridge where it’s cold and away from light.

When it comes to mayonnaise, there are a few key facts that everyone should know. For example, mayonnaise can last in the fridge for up to three days. If it starts to smell bad, it’s time to toss it out. And if you have any doubts about whether or not mayonnaise is still good, toss it and try again later. 


Mayo can last in the fridge for up to a week if it’s stored in an airtight container. However, if mayonnaise is stored in a plastic bag or open container, it will only last 3-4 days. Mayo will spoil faster when it’s exposed to moisture, so make sure to store it away from any water sources. 

It’s always a dilemma – do you reach for the mayonnaise or skip it altogether? If you open the mayonnaise and it has separated, it’s bad and should be thrown away. If all else fails, store refrigerated mayo in an airtight container


If you’re not sure if mayonnaise is still good, try adding 1 tablespoon of vinegar to see if that makes a difference. If you see signs of spoilage, like mold or whiteheads, it’s time to toss it! So, now that you know how to store mayonnaise and how long it will last, it’s time to get cooking!
