Why Make Candles From Used Cooking Oil?
The appeal of making candles from used cooking oil extends far beyond simple craftiness. Here’s why this project is gaining popularity:
Eco-Friendly Alternative
First and foremost, it’s an incredibly eco-friendly way to reduce waste. Instead of contributing to landfill overflow or potentially clogging your plumbing system, you’re transforming a byproduct of cooking into something useful and beautiful. By repurposing waste, we actively participate in a circular economy, minimizing our environmental footprint. The shift towards sustainable living is not just a trend, it’s a necessity, and upcycling your kitchen oil is a fantastic step in the right direction.
Cost-Effective Crafting
Candle-making supplies can sometimes be pricey. By using used cooking oil as your base, you significantly reduce the cost of this hobby. You’re essentially getting a major component for free! This makes candle making accessible to everyone, regardless of budget constraints. It’s an economical and resourceful way to craft handmade gifts or add a touch of warmth and ambiance to your own space.
Unique and Personalized
Every batch of used cooking oil candles is a little different, based on the type of oil you use and the scents you incorporate. This ensures that each candle is unique and has its own character. From the subtle hint of garlic from your infused olive oil to the warm aroma of a spice blend from your last deep fry, the possibilities for personalization are endless. This is about more than just candles, it’s about storytelling and expressing yourself through scent and light.
Therapeutic Crafting
The process of crafting candles can be incredibly therapeutic. From the methodical filtering to the patient pouring, each step is an opportunity to slow down, focus, and enjoy the present moment. The quiet focus involved can be meditative, providing a healthy break from the fast pace of modern life. This isn’t just about crafting a candle; it’s about crafting a moment of peace and mindfulness.
What You’ll Need to Get Started
Before you dive into the wonderful world of upcycled candle making, let’s gather the necessary supplies. You probably have most of these items already:
- Used Cooking Oil: This is, of course, the star of the show. Be sure to use cooking oil that has cooled completely.
- Fine-Mesh Strainer or Cheesecloth: For filtering out any food debris from the used oil.
- Glass Jar or Heat-Resistant Container: To store and pour the candle mixture. Jars from old candles are perfect.

Step-by-Step Guide to Making Cooking Oil Candles
Ready to get started? Let’s transform that used cooking oil into something amazing:
Step 1: Collecting and Preparing the Oil
After cooking, allow your used oil to cool down completely. This is important for safety. Once cooled, carefully pour the oil through a fine-mesh strainer or several layers of cheesecloth into a clean, heat-resistant container. The goal here is to remove any food particles that may still be present. You might need to filter it multiple times to ensure it’s completely clean. A thoroughly filtered oil is essential for a smooth-burning candle.
Step 2: Neutralizing Odors
Used cooking oil, even when filtered, might retain some of its original scent. To eliminate this, prepare a neutralizing solution. A simple mix of equal parts water and white vinegar works well. Combine the filtered oil with about 10% of this vinegar solution in a clean jar. Shake it vigorously for a few minutes, then let it sit for about 30 minutes. After it settles, you’ll see the vinegar solution separated at the bottom. Carefully pour off the neutralized oil, leaving the vinegar and water behind. Repeat this process if needed until the oil is odorless. Alternatively, you can purchase a specific odor neutralizer designed for candle making from a craft store if the vinegar solution is not enough.
Step 3: Preparing the Wicks
While your oil is being neutralized, prepare your wicks. Cut them slightly longer than the height of your chosen container. Many wicks come with a small metal base. If yours don’t, you can use a bit of melted wax or glue dot to secure the wick to the center of your container’s base. This keeps the wick in place when you pour the oil. Make sure the wick is standing straight and centered. This is crucial for even burning. You could use a couple of chopsticks or skewers to secure the top of your wick when pouring the melted oil to prevent the wick from moving.
Step 4: Melting the Oil
Now it’s time to melt the filtered and neutralized oil. Use a double boiler or a heat-safe bowl set over a pot of simmering water. Gently heat the oil until it is completely melted and flows easily. Avoid overheating the oil. This can release harmful chemicals and can make it dangerous. This is a crucial point that requires patience.
Step 5: Adding Fragrance and Colors (Optional)
This is where you can let your creativity shine. Once the oil is fully melted, you can add essential oils or candle fragrance oils. Begin with a few drops and add more until you achieve your desired scent. If you’d like, you can add a few drops of candle dye to color your candles. Stir the mixture gently with a wooden skewer or chopstick to ensure everything is evenly distributed. Be careful not to add too much fragrance or dye, as this can affect the burning properties of the candle. Remember, always use products that are specifically designed for candle making.
Step 6: Pouring the Oil
Carefully and slowly pour the melted oil into your prepared containers with the wicks already in place. Leave a small gap at the top of the container to prevent spillage. If you have the wick holders from old candles, you can use those to keep the wick upright. If not, secure it with chopsticks or skewers. Let the candles cool and set at room temperature. Avoid moving the candles during the cooling process. The time to solidify will vary depending on your container size. It will generally take at least 24 hours to fully cure.
Step 7: Curing and Enjoying Your Candles
Once the candles have completely solidified, they are ready to use. Trim the wick to about ¼ inch before lighting. Always burn candles on a heat-resistant surface and in a well-ventilated area. Never leave a burning candle unattended. The initial burn will be the most critical for the entire life of the candle. Make sure you have a full melt pool covering the entire surface before you extinguish the flame. For best burn performance, allow your candles to burn for at least two hours on their first burn. This can ensure that the wax melts all the way to the edge to avoid tunneling.
Tips for Making the Perfect Cooking Oil Candles
Here are a few extra tips to enhance your candle-making experience and ensure great results:
- Experiment with Scents: Mix and match essential oils to create unique and personalized aromas.
- Use Different Containers: Explore different shapes and sizes of glass jars, tea cups, or metal tins to add personality to your candles.
- Practice Safety: Always be careful when working with hot oil and open flames. Ensure your work surface is heat resistant and that you have a clear workspace.
- Monitor the Burn: If you notice a flame is too high or the wax is burning unevenly, extinguish the candle and adjust the wick before relighting.
- Patience is Key: Take your time with each step of the process. Candle-making should be enjoyable and stress-free.
Transforming used cooking oil into beautiful, fragrant candles is a rewarding project that benefits both you and the environment. By upcycling, you are reducing waste, exploring your creative side, and adding a personal touch to your home decor. So, the next time you’re about to discard that used oil, remember the possibilities it holds. This is more than just making candles; it’s about making a change, one repurposed batch at a time.
