Spraying vinegar on keys: why it's so widely recommended and what it's used for
A clever key-cleaning hack that I'm almost sure you've overlooked when it comes to your own set.
House keys are often overlooked when it comes to cleaning, despite being touched by multiple people and carrying germs. A simple vinegar hack can effectively clean and disinfect keys without harsh chemicals. Vinegar's properties help remove light rust, dissolve skin oils and sweat, and it's non-toxic. To clean keys, spray them with white vinegar, let it sit for a few minutes to loosen dirt, then wipe with a dry paper towel. Be sure to dry keys thoroughly and avoid using this method on electronic keys.
