The vinegar you buy in stores, whether apple cider, balsamic, white, or another kind, contains 5 percent acetic acid, which does have antimicrobial properties. Various studies have found that vinegar, usually in combination with table salt or hydrogen peroxide, can inhibit the growth of some strains of E. coli. It's also an effective mold killer. Its production doesn't take such a toll on the environment, and while it can be pungent, a whiff of vinegar cleaning mix won't sear your airways.
When it comes to food safety, vinegar hasn't been as thoroughly tested as chlorine bleach. Studies that find it kills germs are generally vague in terms of how much of the germs are killed and how much are left behind. While we often recommend it for general cleaning, it would be great to have more specifics on its germ-killing capabilities, especially for people who have someone with a compromised immune system in their home
