What to Do With Leftover Tea Leaves - 9 Ways to Use Leftover Tea Leaves and Powder

While tea leaves or tea powders are essentially steeped and consumed as a drink with health benefits, this is not the only way they could be used. In fact, even the boiled tea leaves for consumption as a healthy drink are not to be put to waste and still have lots of benefits for everyday use. Instead of discarding used tea leaves after enjoying your daily cup, consider how they can become a valuable part of your skincare routine, household maintenance, or garden. Used tea leaves are a versatile and sustainable solution to many everyday needs, from acting as a gentle exfoliant to freshening up musty shoes. Not only does this help reduce waste, but it also gives you the added satisfaction of making the most out of a simple ingredient. Here are just some of the countless uses of used tea leaves or tea powders after being steeped and consumed as a healthy drink:

1. You Can Use it as an Exfoliant on Your Face or Body.

Tea leaves are a natural antioxidant for the body. The antioxidants and caffeine will help rejuvenate your skin and clear up redness. Thus, crush those used, after-boiled tea leaves into small, fine grains and mix them with your favorite facial wash to scrub all over your face as a home-made scrub. For the body, you may leave your tea leaves as is and mix them with your handy body wash for a more vigorous scrubbing to remove dead skin and to revitalize all over your body to leave you with fresh and smooth skin thereafter. Containing properties that help with inflammation, people afflicted with sunburns just need to soak some cooled tea leaves and apply them to the burnt area. Some would also do the same to their fresh wound to manage the damage. The tannins found in tea leaves help stop bleeding by coagulating the blood. 

Using tea leaves in your skincare routine is cost-effective and environmentally friendly. By reusing what you would otherwise throw away, you’re giving your skin a natural, chemical-free treatment while reducing waste. This practice aligns perfectly with sustainable living habits, especially for those seeking natural remedies and DIY beauty solutions. Whether it’s to pamper your face, soothe a sunburn, or gently heal a minor cut, used tea leaves are an unexpected yet effective skincare hero from your kitchen.

2. Use as Eye cream. Say Goodbye to Those Dark Circles

With the active ingredients of caffeine and antioxidants in your favorite tea leaves, these may be mixed with your favorite undereye cream by grinding them into fine particles and letting them sit on those eye bags overnight. By morning, you will be surprised to see your eyebags smaller and your eye area refreshed and revitalized.

This simple yet powerful remedy can be a game-changer for those with tired eyes or long nights. Instead of investing in expensive eye serums filled with artificial chemicals, this natural solution offers a gentler, more affordable option. Regular use can gradually reduce puffiness, even skin tone, and promote a youthful appearance. Plus, the cooling sensation of the tea provides instant relief, making it a soothing ritual before bed. It’s an easy, sustainable beauty hack that gives your skin the nourishment it needs—right from your leftover tea.

3. Make Green Tea Mouthwash

While tea, just like coffee, may stain our teeth, it can actually help your dental health as long as you drink it unsweetened. Because of the catechins, drinking steeped tea leaves can even lower your chances of losing your teeth. If anything, tea can help wean you off soda! Did you just eat something that is unpleasantly smelly or munch something with garlic? A lightly flavored tea can come to the rescue when you suddenly need to say hello to someone and do not have mouthwash on hand. Just swish some tea, and you can drink this mouthwash as well. The used tea leaves could also be ground and mixed with baking soda to make an instant herbal toothpaste.

This natural alternative is not only gentle on your gums but also helps maintain oral hygiene without the harsh chemicals found in conventional mouthwashes. Thanks to the antibacterial and anti-inflammatory properties of green tea, regular rinsing can reduce plaque buildup, freshen breath, and even calm irritated gums. Using leftover tea leaves in this way supports a holistic approach to oral care—perfect for those who prefer eco-friendly solutions. Whether at home or on the go, this quick and easy green tea rinse keeps your mouth clean, your breath fresh, and your teeth protected.

4. For Baking

Who told anyone that tea leaves are just meant to be steeped and drunk? There are already lots of cake and dessert recipes out there using tea leaves as the main ingredient. While some would grind the tea leaves and put them in the batter, usually the tea leaves are being steeped and the water that was boiled with the tea leaves is being mixed with other baking ingredients to make those mouth-watering tea-infused cakes, cookies, cupcakes, or other desserts. The tea leaves could also naturally color your frosting for your desserts.

This creative use adds a subtle flavor twist and elevates your baked goods with a touch of elegance. Tea-infused desserts are gaining popularity in home kitchens and patisseries, from earthy matcha cheesecakes to floral Earl Grey macarons. By repurposing used tea leaves, you introduce a unique aroma and depth of flavor to your confections while minimizing waste. It’s an inventive way to experiment in the kitchen and surprise your guests with something delicious and delightfully unexpected.

5. As a Freshener or Deodorizer.

Tea leaves naturally absorb nasty smells. Those used-up tea leaves can be dried and put inside your stinky shoes or moldy leather bags to absorb the moisture and smell inside your belongings. You could also use tea leaves as a deodorizer for your refrigerator, cupboards, or drawers by simply leaving the tea leaves inside, and they will naturally absorb the rotten smell inside, just like baking soda.

This method is a simple and sustainable way to keep your spaces smelling clean without relying on artificial air fresheners or chemical sprays. Plus, it’s incredibly cost-effective—you're giving new purpose to something that would otherwise be discarded. Place the dried tea leaves in small sachets or breathable fabric pouches for easy placement around the house to make it even more convenient. Whether tucked inside gym bags, under car seats, or in storage boxes, tea leaves offer a natural solution for neutralizing unpleasant odors while leaving behind a light, earthy scent.

6. As a Floor Shiner or Cleaning Agent.

Tea leaves could add shine and a slight tint of color to your hardwood floors when rubbed by a rag dipped in steeped tea leaves; just be sure to test it on a small area before you rub down the whole floor! You can even put it in a spray bottle to clean glass.

This eco-friendly cleaning trick enhances the natural beauty of your surfaces and avoids harsh chemicals. The tannins in tea help cut through grease and grime, making it surprisingly effective for tackling everyday dirt. Tea can offer a gentle yet powerful clean, whether refreshing wooden furniture, buffing up dull floors, or giving your windows a streak-free shine. It's a practical, budget-friendly solution for anyone looking to maintain a sparkling home with natural ingredients already in the kitchen.

7. As an Art Attack

Have you ever noticed the stains your tea leaves leave behind when they dry up after being steeped and consumed? Have you ever heard of the concept of coffee stain art, where coffee is used as a paint brush on canvas? Tea stains could be used for the same concept as well! There are various tea stain art works that are already out on the market, so if you love art, you may want to try doing this as well! You want to create a unique, vintage look for your boring, ordinary white shirts. Soak your white tops or whatever fabric you may have, such as curtains, in brewed tea, and voila! You already have a safe and cheap alternative to conventional dyes!

This creative approach brings a rustic, antique aesthetic to your crafts and fabrics and encourages sustainable artistic expression. From handmade greeting cards and aged journal pages to DIY wall hangings and customized apparel, tea-staining opens up a world of natural, earthy tones that synthetic dyes often struggle to mimic. It’s a fun and eco-conscious way to personalize items while celebrating imperfections and organic beauty. Whether a seasoned artist or a weekend DIYer, tea leaves might become your new favorite art supply.

8. As Compost and Fertilizer

To help your compost heap, simply throw your old tea leaves into the compost, as tea leaves help speed up the process of composting. Loose tea leaves would naturally compost without worrying about the bags not being biodegradable. Since too much of something is bad, there is such a thing as plants getting too much water. Tea leaves can also help to absorb water if placed at the bottom of your soil, so that plants will be saved from too much moisture and instead the overall moisture will be more efficiently redistributed over time.

This dual-purpose use makes tea leaves an ideal addition to any garden, big or small. Packed with nutrients like nitrogen, they enrich the soil and support healthy plant growth. Whether maintaining a backyard vegetable patch or just a few potted herbs on your windowsill, incorporating used tea leaves into your gardening routine can improve soil structure, balance moisture, and even deter certain pests. It’s a simple, sustainable way to nurture your green space while reducing kitchen waste.

9. To Shoo Away Those Nasty Rodents

No one would ever want rodents lurking around their houses, causing damage to their food stashes and sometimes to their favorite stuff, such as bags and clothes. Rodents are actually disgusted with the smell of tea leaves, so you may want to dry up your used tea leaves and simply leave them where rodents usually go to stay away from your house. 

This natural repellent is a safer alternative to chemical traps or poisons, especially for homes with children or pets. Placing dried tea leaves in corners, under sinks, behind appliances, or near entry points creates a barrier that rodents find unpleasant. You can even pair the leaves with essential oils like peppermint or eucalyptus for an extra kick. It's a simple, non-toxic method that helps maintain a clean and rodent-free space while using your tea remnants well.
