To make a new candle, melt the old wax and pour it into a new container with a wick. You can also add essential oils to create a nice fragrance.

What You'll Learn

Melt wax in a saucepan or oven
To reuse citronella candles, you can melt the wax in a saucepan or oven and then pour it into a new mould to create a new candle. Here's how to do it:
Melting Wax in a Saucepan
First, remove the wax from your old candle jars. You can use the freeze-and-scrape method to do this. Place the wax in a saucepan and melt it over low heat. You can also use the double boiler method, which involves placing the wax in an old jar and putting that jar in a pot of water. This is safer than heating the wax directly in the pot.
Melting Wax in an Oven
If you prefer to use an oven, preheat it to its lowest setting. Remove any labels or stickers from the jar and place it inside the oven. Once the wax is melted, scoop it out and reuse it.
Adding Citronella Oil
Once the wax is melted, you can add citronella essential oil to create a bug-repellent candle. Add one ounce of citronella oil per six cups of melted wax. You can also add other scented essential oils, such as grapefruit, to offset the smell of citronella.
Pouring the Wax
Prepare your new container by securing a wick in place. You can use a jar, tin, teacup, or votive glass. Pour the scented wax into the container and let it set completely. You can also pour the wax into small moulds, such as muffin liners, to create wax melts or fire starters.
Remember to be cautious when handling hot wax and always work in a well-ventilated area.

Pour wax into a mould or container
To reuse citronella candles, you can melt the wax and pour it into a mould or container. Here is a step-by-step guide:
First, gather your materials. You will need a few old candles, preferably made from the same type of wax and with complementary scents. You will also need a heat-proof container, such as a jar, tin, teacup, or votive glass, to serve as your new candle mould.
Next, prepare your container by cleaning it and removing any labels or stickers. If you are using a wick, use a hot glue gun to adhere the wick tab (the metal wick holder) to the bottom of your container. Wrap the wick around a stick and rest it on the top of the container. Alternatively, you can thread the wick through a metal wick base and crimp it shut with pliers.
Now it's time to melt the wax. Remove the wax from your old candles and place it in a saucepan. Melt the wax over low heat, using a double boiler method to avoid direct contact with the heat source. You can also melt the wax in the oven at its lowest temperature or use a microwave if your container is microwave-safe. Always exercise caution when handling hot wax.
Once your wax is melted, you can add essential oils or fragrances if desired. Citronella oil is great for insect repellent candles, and you can add complementary scents like grapefruit to offset the strong smell of citronella.
Finally, carefully pour the melted wax into your prepared container, stopping about half an inch below the rim. Let the wax harden completely before lighting your new citronella candle.
By following these steps, you can create new citronella candles from reused wax, giving your old candles a new lease of life and enjoying their beautiful scent all over again.

Add essential oils
To reuse citronella candles by adding essential oils, follow these steps:
First, collect the candle wax from your old citronella candles. You can use a variety of waxes, such as beeswax, soy wax, or paraffin wax. The amount of wax you need will depend on the size of your new container. Next, melt the wax. This can be done in a few ways: using a saucepan over low heat, a double boiler, or an oven on its lowest setting. If using a saucepan or double boiler, place the wax in a jar or pot before heating. Ensure you do not put the wax directly into the pot, as this can be dangerous.
Once the wax is melted, it's time to add your essential oils. For a strong citronella scent, use citronella essential oil. You can also experiment with different oils to create unique fragrances. For example, grapefruit essential oil is a popular choice to combine with citronella. Add the essential oils to the melted wax and mix well.
Before pouring the wax into your new container, prepare the wick. Cut a piece of wicking material that is 2 inches taller than your container. Thread the wick through a wick tab, available at craft stores, and secure it with a knot. Place the wick in the centre of your container, and pour a small amount of wax over it to hold it in place.
Now, carefully pour the scented wax into your chosen container, ensuring the wick remains centred and secure. Let the wax set completely before lighting your new citronella candle.
You can also add essential oils to your citronella candles by making wax melts. Simply pour the scented wax into ice cube trays or moulds and allow them to harden. These wax melts can then be used with a wax warmer to fill your space with fragrance.

Insert a wick
To reuse citronella candles, you will need to melt the wax and pour it into a new mould. This can be done by placing the wax in a saucepan and melting it over low heat, or using a double boiler method. Once the wax is melted, it can be poured into a new container, such as a jar, tin, or teacup.
When inserting a wick, follow these steps:
Firstly, select a wick that is sized appropriately for your container. A zinc-core wick or a pre-waxed wick are good options for citronella candles. Cut the wick to a length that is 2 inches taller than your container. You can find wicks and wick tabs at craft stores.
Next, prepare the wick by threading it through a wick tab. This will help to secure the wick at the bottom of your container. You can use hot glue to adhere the wick tab to the bottom of your container. If using a tin, it is recommended to run a bead of glue along the inside seams to prevent leaking.
Now, centre the wick in the bottom of your container. You can use a wooden skewer or a stick to help hold the wick in place. Rest the skewer or stick on the rim of the container.
At this point, you can pour a small amount of your melted wax over the wick to help hold it in place. Allow this to set completely before proceeding.
Finally, carefully pour the rest of your melted wax into the container, stopping about 1/2 inch below the rim. Allow the wax to set completely before lighting your candle.

Let the wax set
After preparing your container, wick, and wax mixture, it's time to let the wax set. This is a crucial step in the process of making citronella candles, as it ensures that your candle will hold its shape and can be safely burned.
The time it takes for the wax to set will depend on the type and amount of wax you're using, as well as the size and material of your container. In general, it's best to let the wax set for at least an hour to ensure it has hardened sufficiently. During this time, you can prepare additional wicks or gather herbs and spices to add to your candles, if desired.
If you're making multiple citronella candles, you can speed up the process by placing the filled containers in a cool place, such as a refrigerator or a cold cellar. This will help the wax harden faster, but be careful not to disturb the wicks or cause any spillage during this time.
Once the wax has set, you can trim the wicks to the desired length and decorate your candles with herbs, flowers, or other embellishments. This step is optional but can add a personal touch to your homemade citronella candles.
Finally, your citronella candles are ready to be burned! Remember always to burn candles on a heat-proof surface and to follow basic candle safety guidelines. Enjoy your homemade creations, and feel confident knowing you've made the most of your old candle wax.
