Can Vinegar Go Bad? Short answer: Nope! As previously mentioned, vinegar is a fermented product. This means it has a "near indefinite" shelf life, its natural antimicrobial properties contributing a great deal.
No, vinegar has an indefinite shelf life and can safely be used for cooking and cleaning, long after its expiration date -- especially when kept in a cool, dark place.

Use in Cooking: Even if it's expired, ACV can still be used in recipes, such as salad dressings, marinades, or pickling vegetables. Just ensure it still tastes good. Cleaning Agent: ACV is an effective natural cleaner. You can dilute it with water and use it to clean surfaces, windows, or even as a deodorizer.
Vinegar is entirely fine to pour down the drain. However, it's acidic nature can present some problems depending on the age and wear on the pipes. But, all-in-all, it shouldn't damage your plumbing regardless of the material.
For an unopened bottle, “Vinegar is quite stable. If it sits on the shelf for five years, it'll still be acidic,” Katz says. “The changes happen as there's more and more air space in the vessel.” For the best quality, you should try to use it up within six months.
White vinegar, also known as distilled vinegar or spirit vinegar, is made by fermenting grain alcohol (ethanol) which then turns into acetic acid. Water is then added to the vinegar, so white vinegar is made of five to ten percent acetic acid and ninety to ninety-five percent water.
Almost Indefinite Shelf Life
Vinegar is a fermented product and has an “almost indefinite” shelf life according to the Vinegar Institute. “Because of its acid nature, vinegar is self-preserving and does not need refrigeration. White distilled vinegar will remain virtually unchanged over an extended period of time.
However, the long shelf life doesn't mean that bacteria can't grow in your vinegar. Once opened and exposed to air, harmless vinegar bacteria may indeed start to grow. The telltale sign? A formation of cloudy sediment, that you can simply strain off before using and never give a second thought to.
Natural vinegar and synthetic vinegar, vinegar is a collective word for products containing acetic acid as an active substance. Acetic acid is obtained in various ways. The acetic acid in natural vinegar is always obtained from an agricultural source. Synthetic vinegar originates in fossil fuels.
Vinegar has been proven to have some disinfectant properties, however it's not nearly as effective at killing harmful viruses and bacteria as commercial cleaners. And because it does not kill 99.999 percent of bacteria and viruses, it doesn't meet the criteria required to be considered a disinfectant.
Does Vinegar Go Bad? No, vinegar doesn't expire. Whether it's a bottle of crystal-clear distilled white vinegar or cloudy apple cider vinegar with the “mother,” vinegar has a virtually indefinite shelf life thanks to its high level of acidity (above 4%).
Sometimes there is sediment, cobweb like or large jelly like discs floating in my vinegar. What is it and is it harmful? This is known as “Mother of Vinegar” and due to the natural fermentation process used to make DYC vinegars; it may develop in the product over time.
The more air vinegar is exposed to over time, the more its overall acidity can drop, so you're not really doing yourself any favors by buying that gallon jug—introducing oxygen every time it's opened for a pour.
Any vinegar can work as an alternative when you don't have a bottle of white vinegar at hand—or if you want to avoid the smell.
Even if your vinegar starts to lose its quality, know that there's nothing inherently wrong with using it besides a slightly different taste and maybe some decolorization. If all else fails, use it to pickle vegetables or clean with it using these vinegar cleaning hacks.
Tools with exposed edges, like kitchen knives, are especially vulnerable to vinegar. Cleaning knives with vinegar can damage the finish and leave the edge pitted, says Frank Spinelli, head of appliance testing for CR. Other common metals in the kitchen that you should keep away from vinegar include aluminum and copper.
"The white cleaning vinegar is a pH of 2.5, which is a very strong acid," she explains. "And while it may eat away the gunk that is on the showerhead or faucet, it can also dissolve the finish from the hardware leaving it dull or a different color altogether."

What's the Shelf Life of Worcestershire Sauce? Hard to say, but easy to store. It lasts up to three years unopened in the pantry. Keep an open bottle of Worcestershire sauce for up to three years in the refrigerator.
Real Salt never expires.
Food only spoils when fungal, bacterial, yeast, or other microbial growth takes place. All of these require water. Salt doesn't contain water, so it doesn't support microbial growth, meaning it won't spoil. In fact, salt is actually used as a preservative for other foods, like meat.
