Vinegar is one of those all-time best-in-show sort of kitchen items to have around, because it can perform so many different life-saving duties. In fact, here's one that I recently learned -- perfect to add to my ongoing list of Why Vinegar is Awesome:

If you have an electric tea kettle with a bit of calcium build-up on the heating element, don't fret. Simply boil a mixture of equal parts vinegar and water, then empty. The calcium will flush out along with the vinegar mix, leaving your tea kettle fresh, new and smelling cleaner than ever.
