How Long Does It Take For The McDonald’s Sweet & Sour Sauce To Expire?

If the sauce has been continuously refrigerated, it typically stays good for about one year.

However, if you’ve simply kept it in your glove department, how long it lasts depends on the temperature and conditions.

If you live in a more temperate environment, you can expect this sauce to last a few months. Further, places with a pretty even temperature will see these sauces lasting quite a while.

But, if it is particularly cold or hot, this sauce may not last long. If this sauce freezes, it typically doesn’t have the same texture after it thaws.

Therefore, leaving these sauce packets where they may freeze is not recommended. With that, hot temperatures tend to be substantially better for these sauce packets.

For example, they don’t tend to spoil after one hot day. Still, they will not last as long. Additionally, hot temperatures can cause them to explode.

For this reason, we don’t recommend keeping them in hotter areas, either.

How Do You Know If McDonald’s Sauce Is Expired?

All McDonald’s sauces do go bad eventually. When they do go bad, they’ll become inedible. Of course, we don’t recommend ever consuming a sauce that has gone bad.

While it won’t necessarily make you sick, it absolutely can. However, determining if the sauce has gone bad can be a bit more challenging.

Generally, you should notice differences in smell, consistency, and taste. If the sauce looks strange, it is probably no longer good.

Also, if the sauce hasn’t been refrigerated, we suggest being more careful before you eat it. Usually, you’ll be able to tell by the taste, if nothing else.

So, try a bit of the sauce before placing it on a sandwich; this will prevent you from ruining your sandwich with a bad sauce.

McDonald’s sauces last for a very long time. In fact, many will last for years before they go bad. However, how you store them matters a lot.

They likely won’t last very long if you simply leave sauces in your car.

For this reason, we highly recommend keeping these packets in a cold place, like your fridge, as this storage option will help them last much longer.

However, if you find an old pack in your car, you may need to be cautious about eating it. Often, you’ll notice the sauce is bad due to a change in texture, color, or flavor.
