Did you know that a clean fridge is actually more energy efficient? It’s true, so toss out your spoiled food and scrub those shelves and drawers with warm soapy water. Remember: Don’t wash a cold glass shelf with hot water; the glass could shatter. Wipe down the exterior thoroughly with a nonabrasive cloth and—last but not least—vacuum the refrigerator coils on the back of the unit.
Oven spills can be tough to remove, because typically by the time you notice them, they’re burnt to a crisp. To handle baked-on spills, spread a paste of baking soda and water over them, and scrub with a toothbrush or plastic scrubbing pad. Add a little vinegar for extra cleaning oomph. Extremely dirty ovens may require a commercial oven cleaner—follow the manufacturer’s instructions for use.
When residue builds up on an iron, stop everything and clean it—or you might just mar your couture next time you press laundry. Apply a paste of baking soda and water to a cool iron, and rub it into the soleplate until stains are gone. To remove mineral deposits from steam ducts, use pipe cleaners. Finish up by filling the water reservoir with a 50-50 solution of vinegar and water, then turning the iron on high for 15 minutes. Cool it down, then dump out the liquid. Repeat with plain water.
When food splatters build up in the microwave, they can seem impossible to remove—but lemons and water can do the trick. Cut a lemon in half and squeeze the juice into a microwave-safe dish, and add one cup of water. Microwave on high for 10 minutes, then let sit for 10 minutes, allowing the citrusy steam to work its magic. Then simply wipe up, and you’re done!

If the interior of your toaster is a crumby mess, a good cleaning is long overdue. Here’s a trick to make the job a snap. Unplug the toaster and place it on top of several layers of newspaper. Pour a tablespoon of kosher salt in each toast slot, and tape a sheet of paper over the slots. Shake vigorously to dislodge any particles. Empty the toaster out and wipe down.
There’s no reason for your stovetop to be plagued by greasy buildup and cooking spills. It’s easy to clean—just time consuming. For a gas range, remove burner caps, grates, and control knobs, and place them in hot, soapy water. Clean the stovetop with a scrubbing sponge and dish soap, then rinse. For an electric range, soak drip pans and knobs, but not the burners; clean around the burners.

Humidifiers that run constantly benefit from weekly cleanings. Unplug the unit and remove the filter, rinsing or replacing as needed. Pour undiluted white vinegar into the base and allow to stand for 15 to 30 minutes. Scrub gently with a soft scrub brush and rinse with plain water. For warm-mist humidifiers, gently brush away any mineral buildup on the heating element. Dry and replace the filter.
Remember: A Clean Kitchen is a Happy Kitchen!
