Surprising Uses For Citrus Peels

Tossing orange, lemon, and lime peels in the trash feels wasteful when you consider how much flavor, fragrance, and cleaning power are packed into that colorful outer layer. Most people peel their citrus and immediately throw away what is, arguably, one of the most valuable parts of the fruit.

The oils in citrus peels are potent enough to cut through grease, fresh enough to eliminate odors, and versatile enough to work in everything from cleaning to cooking. Before you toss those peels in the compost or garbage, consider putting them to work around your home.

Here’s how to utilize every piece of that citrus instead of sending it directly to the landfill.

Make all-purpose cleaner

Fill a jar with citrus peels, cover them with white vinegar, and in two weeks you will have a degreaser that cuts through the toughest grime and leaves fresh, citrus-scented surfaces —not vinegar-smelling ones. The grime will naturally break down due to the citrus oils, while the vinegar’s acidity boosts the cleaning power of this solution.

Transfer it to a spray bottle and use it on counters, sinks, and stovetops.

Deodorize your garbage disposal

Throw a few peels into the disposal with cold running water and grind them up. The oils coat the blades and the inside of the disposal, eliminating odors, while the texture helps scrub away stuck-on gunk.

Once a week, your kitchen sink will smell so much fresher. It’s way cheaper than those disposable cleaning tablets and works just as well.

Create candied peels for baking

Simmer citrus peels in sugar water until they are translucent and tender, then roll them in sugar and let them dry. They become chewy, sweet treats on their own, or they can be chopped up and added to cookies, cakes, or chocolate bark.

It’s a traditional confection that turns what would be trash into something you’d actually pay money for at a fancy bakery.

Freshen up your refrigerator

Place a few citrus peels in a small bowl in the back of your fridge, and they’ll absorb odors while releasing a light, fresh scent. Replace them every few days when they dry out.

For some people, it works much better than baking soda, and your fridge will smell like citrus instead of just neutral.

Make firestarters for camping

Dried citrus peels work well as fire starters because their oils become flammable and burn slowly. Save the peels, dry them thoroughly, and package them for the next campout.

They catch easily, burn long enough to get kindling going, and smell a whole lot better than chemical fire starters.

Add olive oil or vinegar

Drop peels into a bottle of olive oil or vinegar and let them steep for a week or two. Oils will infuse into the liquid, creating flavored versions to use over salad dressings or marinades; lemon-infused olive oil is notably good drizzled over fish or roasted vegetables.

Make sure the peels are submerged to avoid mold.

Clean your microwave with ease

Place citrus peels in a bowl of water and microwave on high for three to five minutes. The steam loosens stuck-on food while the citrus oils cut through grease and eliminate odors.

When it’s done, just wipe down the inside with a cloth; everything comes off easily without scrubbing. Your microwave will smell fresh, not like last week’s leftovers.

Repel pests in the garden

Try scattering citrus peels around plants that cats, aphids, or ants are bothering. Most pests detest the rich aroma and will avoid it.

Replace the peels every few days, as they will dry out and lose their effectiveness. It is nonchemical and does not hurt animals in any way.

Simmer them for natural air freshener.

Place the citrus peels in a pot with water, cinnamon sticks, cloves, or vanilla extract, and simmer on low heat. The steam carries the scent throughout your house, and your home smells as though you have been baking all day.

That is especially nice for the holidays or when you want your home to smell inviting without lighting candles or using plug-in air fresheners.

Scrub off stubborn stains.

Sprinkle baking soda on tough stains in sinks, tubs, or cutting boards, then scrub with the cut side of a citrus peel. The combination of the abrasive baking soda and the acidic oils in the peel makes for a powerful cleaning paste.

It works particularly well on coffee stains, hard water deposits, and soap scum.

Flavor water or tea naturally

Toss fresh citrus peels into a pitcher of water or pot of tea while it’s steeping. The oils bring in flavor without the bitterness that comes from squeezing whole citrus into drinks.

It’s a great way to make plain water more interesting, without adding sugar or artificial flavorings.

Polish stainless steel and copper.

Rub the cut side of a lemon or lime peel directly onto stainless steel appliances or copper pots. It removes tarnish and restores shine by dissolving oxidation with citric acid, and the oils leave a streak-free finish.

Rinse with water and buff dry with a soft cloth to make your pots and pans look almost new again.

Make homemade potpourri

Dry citrus peels thoroughly, then mix them with cinnamon sticks, whole cloves, and dried flowers or herbs. Place the mixture in a bowl or sachet for natural scenting of drawers, closets, or rooms.

Unlike commercial potpourri, this actually smells like the real ingredients instead of synthetic fragrance, and you can customize the scent however you like.

Zest and freeze for future cooking

Before peeling citrus fruits, grate off the zest and freeze it in small portions. This zest contains concentrated oils, which add bright flavor to everything from pasta to baked goods.

Frozen zest lasts for months and keeps it on hand, even when you don’t have fresh citrus. Just grate what you need straight from the freezer into whatever you’re cooking.

From waste to resource

The shift from automatically throwing away citrus peels to seeing them as a functional ingredient requires little effort, only a slight change in habit. From cleaning and cooking to freshening up your space, those peels have more life left in them after you’re done with the fruit.

It’s one of those straightforward ways to reduce waste while actually getting something in return —a better deal than most recycling offers.
