  • 1. Whip Up An Enzyme Cleaner

    <a href="http://earth911.com/news/2011/11/11/save-cash-go-diy/" target="_hplink">DIY cleaning products</a> are the latest back-to-basics trend for Earth-lovers who want to save money, cut back on packaging waste and reduce their family's exposure to chemicals. But if your tonics of vinegar, water and baking soda can't stand up to tough messes, you don't have to go back to store-bought alternatives! Whip up an enzyme cleaner from your citrus scraps, and start cleaning everything and anything without harsh smells or chemical additives. Made from fermented citrus scraps, enzyme cleaners are powerful enough to blast away stuck-on messes but gentle enough to be used around food, children and pets. And when we say you can use enzymes to clean anything, we mean it: Dishes, laundry, floors, porcelain, tile, stove tops, counter tops - even clogged drains. Typically, enzyme cleaners take about three months to ferment, but <a href="http://www.ecokaren.com/2012/05/citrus-enzyme-cleaner-recipe/" target="_hplink">this recipe</a> from <a href="http://www.ecokaren.com/" target="_hplink">EcoKaren</a> blogger Karen Lee will only take about two weeks. And the inventive homemaker will even tell you how to dilute and use your miracle cleaner at home. <a href="http://earth911.com/news/2012/03/27/green-spring-cleaning/" target="_hplink">Cleaning and Greening: Earth911's Green Spring Cleaning Guide</a>

  • 2. Polish Your Cookware

    Brass, copper and stainless steel cookware add an elegant touch to any kitchen, but cleaning and polishing can be such a chore! Give those sore limbs a rest by using citrus scraps to scour, clean and polish cookware (no elbow grease required!). Lemon rinds and halved lemons used for juice are perfect for removing greasy messes from your copper pots and pans: Just sprinkle some salt on the pot for added abrasion and scrub with the inside of the peel until it shines. You can also add salt to your halved lemons and use them to polish brass and stainless steel in the kitchen, as well as remove hard water stains and soap residue in the bathroom. <a href="http://earth911.com/news/2011/02/14/handbook-on-eco-friendly-household-cleaners/" target="_hplink">Clean the Eco Way: Handbook on Eco-Friendly Household Cleaners</a>

  • 3. Wash Fruits And Veggies

    Looking for a reuse idea for those lemons you used for zest? Our tip: Cut them in half, extract the juice and use it as an eco-friendly cleanser for your fruits and veggies. To make your produce cleanser, simply combine about 2 tablespoon of lemon juice, 4 tablespoons of vinegar and 2 cups of water, and add to a clean reusable bottle. Use your mixture to naturally remove dirt and other impurities from your produce before chowing down. Note that some non-organic produce picks, commonly known as "<a href="http://earth911.com/news/2010/05/18/is-this-peach-safe-to-eat/" target="_hplink">The Dirty Dozen</a>," can harbor pesticide residue even after they have been washed. This solution may not remove all residual pesticides from "Dirty Dozen" crops. So, choose organic for these fruits and veggies whenever possible. <a href="http://earth911.com/news/2012/05/23/edible-gardening-basics/" target="_hplink">Grow Your Own: 5 Simple Ways to Start Growing Edibles</a>

  • 4. Fight Allergies

    Springtime allergies got you down? Fight back with a waste-free tea made from citrus scraps, and start seeing results fast. Just save your leftover grapefruit rinds and use them to make grapefruit tea, an age-old tonic that <a href="http://www.centerfornaturalmedicine.com/newsletters/Flu and Cold.htm" target="_hplink">some say</a> breaks up mucus and reduces allergy symptoms. To make your tea, simply mince the peel of one large grapefruit and boil it with about 8 cups of water. Remove boiling mixture from heat, and allow to steep for 15 minutes. Strain to remove grapefruit rinds, and add lemon and honey for flavor if desired. Store any leftovers in a sealed container in the refrigerator for up to three days. <a href="http://earth911.com/news/2012/04/06/eco-cleaning-for-allergies-and-asthma/" target="_hplink">Show Allergies Who's Boss: Eco-Cleaning for Allergies and Asthma</a>

  • 5. Boost Your Laundry

    Lemon scraps have loads of useful cleaning applications all over the house, and the laundry room is no exception. You can <a href="http://www.ecokaren.com/2012/05/citrus-enzyme-cleaner-recipe/" target="_hplink">use your enzyme cleaner</a> directly in the wash. But if you don't want to wait two weeks to get started, simply add juice from zested lemons to the wash cycle to boost your detergent's power. For a mild, stain-free bleach, soak delicates in a mixture of lemon juice and baking soda (or a combination of lemon juice, lemon rinds and water - depending on what you have in your scrap bin). Allow to sit for at least 30 minutes before washing, and watch clothes come out clean. <a href="http://earth911.com/news/2012/01/27/how-to-save-energy-while-doing-laundry/" target="_hplink">Shrink Your Footprint: How to Save Energy in the Laundry Room</a>

  • 6. Clean Your Shoes

    Got a pair of less-than-shiny shoes in your closet? Don't throw them away! Use your citrus scraps to clean them up on the cheap. Just spray your grungy shoes with lemon juice (or rub with a halved lemon), and let them sit in the sun for a good-as-new look. <a href="http://earth911.com/news/2011/08/17/10-reuse-ideas-for-food-scraps/" target="_hplink">Find Out: How to Shine Shoes with Banana Peels</a>

  • 7. Scour Away Tough Stains

    The powdered cleaners used to scour away soap scum in the bathroom and de-grease stuck-on foods in the oven and microwave can be harsh, stinky and, often times, laden with potential toxins. Nix the chemicals - without skimping on that shiny clean - by making your own scouring powder from grapefruit scraps like <a href="http://www.crunchybetty.com/" target="_hplink">Crunchy Betty </a>blogger Leslie. Just dry out your grapefruit scraps, grind them in a coffee grinder, add a few kitchen ingredients and voilà - naturally clean! <a href="http://www.crunchybetty.com/the-great-grapefruit-scouring-scrub" target="_hplink">Check out Crunchy Betty</a> for step-by-step instructions and tips for using your grapefruit scouring powder. <a href="http://earth911.com/news/2011/08/17/10-reuse-ideas-for-food-scraps/" target="_hplink">Clean with Your Leftovers: 10 Reuse Ideas for Food Scraps</a>

  • 8. Keep Bugs Away

    Unfortunately, bugs and warm weather tend to go hand-in-hand. But you don't have to resort to pesticides to keep creepy critters at bay. Just use your old orange peels instead! If you notice ants hanging out in your kitchen, just place a few orange peels around problem areas. Although you may think that fruit would attract ants, the little buggers actually hate the acidic scent of orange peels, and they'll move on to a more pleasing environment. When rubbed on skin, orange peels are also an effective mosquito repellant. Our tip: Bring a few orange peels in a reusable container on your next picnic, camping trip or beach getaway for a mosquito-free afternoon. <a href="http://earth911.com/news/2009/08/21/is-an-alternative-to-pesticides-hiding-in-your-pantry/" target="_hplink">Keep Bugs Out of the Garden, Naturally: Is an Alternative to Pesticides Hiding in Your Pantry?</a>

  • 9. Get Hair And Skin Summer Ready

    Want to lighten up your look a bit for summer? Don't waste money on pricey highlights at the salon! Take an all-natural approach and lighten your hair with lemon juice instead. Our tip: Mix the juice of one lemon and a teaspoon of salt in a spray bottle, spritz through locks and head out into the sun for a few hours. Or try a <a href="http://earth911.com/news/2011/08/12/color-your-hair-at-home-naturally/2/" target="_hplink">lemon and chamomile tonic </a>for more dramatic lightening results. And to zap summer shine, simply rub a sliced lemon over your face after cleansing, and you'll stay sheen-free all day!

  • 10. Keep Food Fresh

    Who knew you could use food scraps to reduce food waste? Use lemon juice to keep your sliced fruits and root vegetables from turning brown (Think: Apple slices, potatoes and your world-famous guacamole). The citrus juice will keep food from oxidizing, which is what causes discoloration. To keep your olive oil tasting fresh for months, just drop a lemon rind or two into the bottle. And, surprisingly, orange peels are great for preserving brown sugar. Just add a few peels, and you'll never have to worry about opening the bag only to find a rock-hard chunk of sugar (yuck!). <a href="http://earth911.com/news/2010/10/08/save-your-food-canning-and-freezing-101/" target="_hplink">Save Your Food: Freezing and Canning 101</a>
