Choosing the right wax
When refilling citronella candles, choosing the right wax is an important step. The type of wax you use will depend on your budget, the burn time you want, and the fragrance strength you're looking for. Here are some of the most common types of wax used for candle-making:
Paraffin Wax
Paraffin wax is the most widely used and inexpensive type of wax for candle-making. It is derived from the oil industry as a byproduct of petroleum. It holds colour and fragrance well, making it a common choice for highly decorative or scented candles. However, it releases soot when burned and is less eco-friendly than other options.
Beeswax
Beeswax has been a popular candle-making wax for centuries. It is natural and eco-friendly, and has a subtle honey scent. Beeswax candles have the longest burn time and produce a warm-toned, smoke-free flame. It is ideal for pillar and taper candles as it doesn't drip easily. However, beeswax has a higher price point than paraffin wax.
Soy Wax
Soy wax is a natural wax made from soybeans, a renewable source. It has a soot-free burn and burns slowly, making it ideal for container candles. Soy wax usually comes in the form of flakes and is easy to work with. It is generally more budget-friendly than beeswax but may be more expensive than paraffin wax in some cases.
Coconut Wax
Coconut wax is a newer option that is becoming increasingly popular. It is harvested from coconuts, a sustainable crop, and burns cleanly with minimal soot. It also excels at holding fragrance and colour, justifying its higher price point.
When choosing the right wax for your citronella candle refill, consider your budget, the burn time, and the strength of the fragrance you want to achieve. You can also blend different types of wax to create a more eco-friendly option, as shown in the example of blending soy wax and beeswax for citronella candles.

Preparing containers
When preparing containers for your homemade citronella candles, you can reuse aluminium or steel cans, glass jars, or any other heat-proof containers. The size of the container will determine how much wax and how many wicks you will need. If you are reusing containers, make sure to remove any labels and residue, then clean and dry them thoroughly. Containers will get very hot when you pour in the wax, so make sure to choose a surface that can withstand the heat.
If you are using glass jars, keep them no taller than a traditional pint-sized jar (about 4-6 inches). The candle will heat up the glass as it burns and can cause the glass to break. If you are using recycled cans, this is not a concern.
If you are using new wicks, place a wick sticker in the centre of each container. If you are using a larger can or wide-mouth Mason jar, you can add multiple wicks. If you are reusing old wicks, tie the end of the wick to a small metal washer to give it weight, and tie the other end around a pencil laid across the container to keep the wick centred.
If you are using beeswax, add an inexpensive oil such as palm oil or fractionated coconut oil to lower the temperature of the burn. This will help prevent your container from breaking if you are using glass. It will also help prevent the candle from cracking or pulling away from the side of the container.

Melting wax
Another approach is to use a double boiler, which involves placing a heat-resistant container with wax inside a pot of boiling water. This method ensures a more gradual melting process and is ideal for larger quantities of wax. Remember to take the necessary precautions when handling hot materials.
Additionally, you can melt wax in an old pan on the stove. This direct heat method is efficient, but it requires careful monitoring to prevent the wax from burning. It is recommended to use a candy thermometer to maintain the desired temperature.
When melting wax, always work in a well-ventilated area to avoid inhaling fumes. Also, be cautious when handling hot wax, as it can cause severe burns. It is advisable to use oven mitts or heat-resistant gloves to protect your hands.
Once the wax is melted, you can add citronella oil and stir it in. The general guideline is to use one ounce of oil for every pound of wax. At this stage, you can also add other essential oils, such as eucalyptus, peppermint, or orange oil, to enhance the scent and create unique combinations.

Adding oil
To add the oil, start by melting your wax in a glass bowl. You can do this by microwaving it for several minutes. While the wax is melting, prepare your candle containers by removing any labels and residue, then cleaning and drying them thoroughly.
Once the wax is completely melted, it's time to add the oil. For a standard 8 oz candle tin, you will need to add 1 oz of citronella fragrance oil. Stir the oil gently into the wax for about 2 minutes to ensure it is fully incorporated. If desired, you can also add other essential oils at this stage, such as eucalyptus, peppermint, or orange oil. These additional oils will enhance the scent of your candle and can further help to repel insects. The recommended amount for these additional oils is 0.5 oz per pound of wax.
After adding the oil, remove the mixture from the heat and continue stirring gently. Allow it to cool slightly before carefully pouring the wax into your prepared candle containers. Be very careful during this step as the wax will be extremely hot. It is recommended to use oven mitts to protect your hands and work slowly to avoid any spills.

Cooling the candle
Cooling your candle is a crucial step in the candle-making process. It is important to let your candle cool completely before using it. This will take several hours. During this time, handle the candles with care as they will be very hot. It is recommended to use oven mitts if you must move them.
To prevent cracks from forming on the surface of your candles, allow them to cool at a slow and even rate. Place the candles in a room with a consistent temperature of 72°-75°F (22.2°-23.9°C) that is free from drafts.
If you are using glass containers for your candles, it is important to note that the candle will heat up the glass as it burns and can cause the glass to break. To prevent this, you can add an inexpensive oil, such as palm oil or fractionated coconut oil, to lower the temperature of the burn.
If you notice cracks or wells developing on your candle as it cools, you may need to add more melted wax to fill it up. Once your candle has solidified, it is ready to be used.
Overall, allowing your candle to cool completely is essential for ensuring the quality and longevity of your homemade citronella candle.
