It’s time for spring cleaning, so I started looking around for the best technology to tackle my dirt. It turns out I may already have it in my refrigerator—or possibly in that half-drunk bottle of wine on the counter. Simple vinegar can apparently clean toilets, kill weeds, fight dandruff, scare off ants, lift deodorant stains, and keep the white from running out of a cracked egg. The acetic acid in vinegar—produced when alcohol ferments—turns into a grease-cutter as powerful as commercial cleaners, according to the Vinegar Institute. (The what? Seriously, there really is one.) Makes me wonder what my salad dressing is doing to my intestines, but I’m too caught up in vinegar trivia to care. —Lauren Aaronson

Most commercial vinegar is labeled as 5% acetic acid, but can have a mass percentage of between 4.0% and 5.5% acetic acid.
And it is great for the windows as well, provided that everybody does what Mr. DenMan here teaches us.
