17 Uses For Citrus Around The House You'll Wish You Knew Sooner

Most of us know that citrus fruits provide dietary benefits, since they are rich in vitamin C, fiber, potassium, and many more essential macronutrients. But lemons, limes, grapefruits, and citrons also contain many properties that make them extremely useful around the house. Whether you're using citrus in the home for aromatherapy or as a natural alternative to heavy-duty cleaners, thinking outside the box when it comes to these fruits can save you money and time.

What is it about citrus that makes it so great around the house? For one thing, citrus fruits are naturally rich in citric acid, which can aid in removing build-ups like mineral deposits and hard water stains. Citric acid can also inhibit the growth of certain bacteria by lowering the pH. In addition to citric acid, citrus fruits contain d-limonene, particularly in the oils found in their peels. D-limonene has insecticidal benefits and can be useful in repelling bugs and pests around the home. With such effective natural ingredients so readily available, you'll be surprised at the many ways citrus can revitalize your home!

Cooked-on stovetop grease is one of the most stubborn and frustrating types of messes to deal with in the kitchen. Luckily, if you have half a grapefruit, lemon, or lime lying around, you can break down some stovetop messes with a little citric acid and elbow grease. Begin by coating the stovetop with a layer of salt, then add citrus juice and let sit for five to 10 minutes before gently scrubbing with a sponge and rinsing clean.

Some sources suggest using half a lemon or lime coated in baking soda directly as a scrubber for stovetops as well, cutting out the extra step involving a sponge in the previous method. Both baking soda and salt can work well on stovetop grease because they have gritty, exfoliating properties that can break up tricky kitchen messes. Scrubbing these ingredients into a stovetop on a regular basis can bypass the expense of chemical stovetop degreasers with materials you likely already have on hand.

In a similar method to the stovetop cleaner previously mentioned, you can revitalize wooden cutting boards by cutting a citrus fruit in half and using it to scrub salt into crevices and knife marks in your cutting board. Once the citrus juice and salt have been left to sit on the cutting board for 10 minutes or so, rinse the cutting board with warm water and let it air-dry. This method is particularly useful for deodorizing porous wooden cutting boards that retain the smell of garlic or onions after use.

It's important to clean cutting boards well, since bacteria can thrive in porous surfaces, such as wood and plastic. Because citric acid is a relatively weak acid in its fruit form, it may make more sense to use a stronger antibacterial method for a deeper clean, particularly if you're using your cutting board to prepare raw meat or poultry. Among the many ways to best clean a cutting board, this method is best for quick deodorizing or stain removal rather than deep cleansing.

A home garbage disposal can be a cleaning lifesaver, but we're all guilty of being a little overzealous with its use. If you've put something you shouldn't down the garbage disposal, or you've simply been using the disposal frequently, it's more likely than not that it will eventually start producing unsavory odors. There's nothing grosser than the smell of rotting food coming from an otherwise clean kitchen sink — but a quick fix with some citrus fruit of your choice can help destroy or mask odors while you identify the source of the problem. Take a fresh citrus fruit of your choice and send a slice down your garbage disposal, then run the disposal with the water flowing. A pleasant citrusy smell will replace the damp, grimy odor and make your kitchen sink smell great!

When using this method, be sure to cut slices of your citrus fruit into small, easily grindeable pieces — otherwise you risk clogging your disposal and causing further problems. Wondering why this hack works? Aside from the naturally strong scent of fresh citrus fruit and peels, there's some evidence that citric acid can kill sources of organic odor. In an interview with Shape on the uses of citrus in fighting body odor, Dr. Geeta Yadav notes that "the alpha-hydroxy acid in citric acid can kill odor-causing bacteria" in armpits; the same principle likely applies to bacteria in your garbage disposal or around the house.

This age-old citrus solution for tarnished metals is one of the most satisfying ways to use citrus around the house; the visible improvement that citrus juice makes to dull and dingy copper and brass is always fun to behold. One method to polish tarnished copper pots uses citrus and salt — simply take half of a citrus fruit (most sites recommend lemon) and dip the cut side in salt. Use the lemon and salt to scrub tarnished areas and let sit for a few minutes, using the same process with the other half of the citrus fruit as needed. When the tarnish has disappeared, run your copper pot under warm water to rinse clean.

For brass or copper dishware and decor, you can also use lemon or citrus juice with baking soda to scrub tarnished areas that the previous method may not effectively reach. Get into the crevices of brass candlesticks and other items by squeezing the juice of half a lemon into a bowl, then mixing in a teaspoon of baking soda. Use a rag or microfiber polishing cloth to scrub the solution into your brass or copper, reapplying as needed. Rinse or wipe clean and dry with an additional cloth.

Citric acid comes to the rescue once again when it comes to whitening clothes and shoes. The stain-fighting properties of citrus can be especially useful for brightening dirty sneakers. To whiten sneakers or other canvas shoes, first soak them in water. In a separate bowl or container mix lemon juice (or the citrus juice of your choice) with water in a 1:1 ratio. Use a toothbrush or scrub brush to apply the citrus solution to the shoes and scrub away. Let the shoes sit for an hour, then rinse clean and leave them out to air-dry.

This hack has the added benefit of deodorizing shoes — or other stained clothes — while brightening up their appearance. It's not the only way to use household pantry items to deodorize sneakers naturally, but if you're worried that other common solutions like vinegar might leave a strong smell, citrus can be a lighter, airier scent for shoes that need less heavy-duty deodorizing.

Home gardeners will know firsthand the importance of starting seedling crops in advance during the late winter months, but seedling pots can be expensive when you're working with a large variety of fruits or vegetables in your garden. You can always make your own planters using cardboard mailers or egg cartons, but if you're a fan of citrus fruits, you may find yourself with an even easier seed-starting option. When snacking on or cooking with your favorite citrus fruit, cut it in half and remove the flesh with a spoon. Use the empty halves of the peel to start seeds by adding an appropriate amount of soil and water. When your seedlings are ready, transplant the whole set-up, peel and all, into a larger pot or garden bed.

This is a great eco-friendly way to start seeds, and the citrus peels will naturally biodegrade — and add nutrients to your soil — over time. Keep in mind that even something as natural as a citrus peel can contain waxes and pesticides from commercial farms. If you're looking to keep your home gardening 100% organic, it's best to implement this method with peels from organic citrus fruits.

According to Consumer Reports, part of the reason that citrus juice is so effective on stains is that the acids in citrus fruits add a charge to the molecules found in stains. The charged molecules then attract the charges in water molecules, which loosen the stains for easier removal. Consumer Reports senior test project leader Rich Handel also states that lemon juice acts as "a mild bleaching agent, and the acidity may help remove the combination that traditional antiperspirants and sweat create on white T-shirts," though he advises that citrus juice should not be used on colors when it comes to laundry.

With such powerful stain-fighting benefits, you may find yourself turning to citrus peels to not only whiten stained shirts or shoes, but to freshen your laundry overall. Add citrus peels to your next load of laundry in the main wash cycle, or soak clothes with the peels prior to your regular laundry routine to loosen dirt and create a lasting natural scent. Make sure you clean the peels well so that the flesh of the fruit doesn't end up smeared on your clean clothes.

Just as citrus can control pests, it can also control unwanted plant life around the garden. Making a weed killer spray that utilizes the acid of citrus juice can be a cheap and sustainable alternative to heavy chemical pesticides. To whip up this weed-busting spray, take 2 cups of distilled vinegar, 3 tablespoons lemon or citrus juice concentrate, 1 ounce of rubbing alcohol, and 2 teaspoons of dish soap and mix thoroughly. Dilute the solution with water as desired. Funnel your mix into a spray bottle and let weeds have it!

A brief disclaimer: The acetic and citric acids in this homemade spray are not only effective on weeds, but all plants. Make sure you use discretion when spraying this weedkiller around the garden, as a careless spraying could damage or kill your flowers or vegetables, too. It might make sense to set your spray bottle nozzle to the concentrated single-stream setting and testing the spray away from delicate plants before applying.
