Lemons are a constant staple in the kitchen. We squeeze them into marinades, shake them into drinks, and grate them over pasta. But once you extract that last bit of juice, the leftover rinds almost always end up tossed right into the trash.

Throwing them out is a huge waste of a great ingredient.

Even after you squeeze them dry, those rinds are still packed with fragrant citrus oils and natural acids that can tackle plenty of problems outside of a recipe. Leftover skins can scrub grease off stovetops, freshen up smelly garbage disposals, and impart a crisp flavor to homemade vinegar or simple syrups.

Don’t ever throw away your lemon peels; here’s how to put every last bit to use around your home.

Simmer for a Natural Air Freshener

Add peels to a pot of water and simmer gently on the stove. For a different scent, include cinnamon sticks or rosemary. The steam freshens the air without artificial sprays.

Steam-Clean the Microwave

Place lemon peels in a bowl with about a cup of water. Microwave for 3 to 5 minutes, then let it sit for a few more minutes.

Shine Stainless Steel

Rub the inside of a lemon peel over faucets or sinks. Buff with a soft cloth to restore a clean, streak-free shine.

Save and Use the Zest

Use a fine grater to remove only the yellow outer layer of the peel, avoiding the bitter white pith. Lemon zest adds depth to baked goods, roasted vegetables, marinades, salad dressings, and even eggs.

Make Lemon Simple Syrup

Simmer equal parts sugar and water with strips of peel. Let it steep, then strain before using. The syrup works well in iced tea, cocktails, or brushed over cakes for moisture and flavor.

Candy the Peels

Simmer peel strips in sugar syrup until soft and translucent. Allow them to dry, then roll in sugar or dip in melted chocolate for a simple homemade treat.

Infuse Vinegar for Cleaning

Fill a jar with lemon peels and cover with white vinegar. Let it sit for one to two weeks, then strain and dilute with water. The result is a natural surface cleaner with a lighter scent than plain vinegar.
