Allow the bins and shelves to dry (outside in the sun if possible). While they're drying, scrub or wipe all the surfaces inside the fridge clean. Be sure to scrub in and under the door gasket. Wipe off the dirty water with clean terry cloth rags until everything is sparkling and dry. Reinstall all the shelves and bins, and put your food away, careful to dump or compost anything that's unrecognizable, moldy, or past its expiration date. Clean off any sticky containers, too, before replacing them.
Do the same thing for your freezer, only wipe down sprayed surfaces immediately so your cleaner doesn't freeze. Put an open container of baking soda in each part of the fridge to soak up stray odors.
Spring is also a good time to clean dust off the condenser coils of your fridge so it works more efficiently and uses less energy. If the coils are on the back of your fridge, pull it away from the wall and unplug it, and use your vacuum cleaner or a damp sponge to remove dust buildup on the coils. If they're on the bottom, unplug your fridge and remove the coil cover panel. Vacuum the coils with the wand attachment until you don't see any more dust (use a flashlight if need be).

Keeping baked-on messes in check will reduce the amount of fumes released every time you turn on your oven. But noxious, chemical oven cleaners can be the harshest products in your kitchen because they contain corrosive ingredients that can burn skin and trigger asthma attacks (particularly if they're in aerosol form). I’d also skip the stove's automatic-cleaning feature, as it uses up fossil fuel and releases all that crud into the air, but if you do use it, be sure to run your exhaust fan the entire time.
It’s best to clean spills and splatters as soon as possible after they happen. For fresh spills, spray or sponge on your nontoxic cleaner (keep it off electric elements), or a solution of 2 cups of hot water, 1 tablespoon of natural dish liquid and 1 teaspoon of borax. Let it sit for 20 minutes, scrub the crud off, and wipe dry with a clean cloth. For really greasy messes, wipe out as much as possible with crumpled newspaper first, then spray the solution and let it sit for 20 minutes before wiping it away.

For older spills, you need to invest some time to reduce the amount of elbow grease required. Moist baking soda is nontoxic and surprisingly effective at loosening even really old baked-on gunk. The trick is getting it to stick to vertical surfaces, and keeping it moist (baking soda does very little if it's dry). After some experimenting, here’s my answer: Mix 2 tablespoons of cornstarch with 2 cups of cold water in a saucepan. Bring it to a boil, whisking constantly, and simmer, still whisking, until it turns clear and gooey. Mix in about a cup of baking soda, or enough so that the mixture becomes a paste with the consistency of yogurt. Smear the paste in a thin layer over all the walls of your oven, keeping it off electrical elements as much as possible. The layer should be thick enough to be white, but doesn’t need to be any thicker than that. Once an hour for the next 12 to 24 hours, at least while you're awake and at home, spray the baking soda paste with water to keep it damp. You'll see the baking soda start to turn brown in spots as it works. After the 12- to 24-hour period, scrub the paste off a test area to see if the grime is well loosened. If it is, get to work on the rest of the oven. Scrub stubborn spots with steel wool or a steel coil scrubber (your fingers will thank you if you use your sponge to hold it). When you're finished, rinse with water.
Cleaning grubby microwaves is easy! Spray the insides with your nontoxic spray, put a cup of water in a microwave-safe container in the center of the microwave, microwave on high until the water boils (in mine, that takes two minutes), and then wait 10 minutes. Use the microwave's timer to keep track. When it beeps, use a sponge to wipe the microwave clean. If any stubborn stains remain, repeat the process but add a splash of vinegar to the water before heating it.

The Small Stuff
Polish off your kitchen duties by attending to the little things. Scrub out all your trash and recycling containers and let them dry outside in the sunshine. Put two cups of vinegar in your dishwasher and run it empty. Run a pot of water with ¼ cup vinegar added through your coffee maker (followed by two pots of plain water). And finally, pour ¼ cup of baking soda, followed by a teakettle of boiling water, down each of your drains. Now…doesn’t your kitchen look and smell wonderful?
