Candle tunneling is a common problem that occurs when a hole forms down the center, leaving unused wax at the edges. This can be caused by a variety of factors such as the initial burn, wick size, burn duration, and temperature. Luckily, there are several simple tricks to fix a tunneled candle and prevent it from happening again. Some methods involve using aluminum foil, a hair dryer, or an oven to melt the hardened wax around the edges and create an even surface. Other prevention techniques include using a candle topper, trimming the wick, and ensuring proper burning during the first use. With the right care, candle enthusiasts can enjoy a beautiful, even burn and make the most of their favorite scents.
What to do with a tunneled candle:

Use aluminium foil to cover the candle, with a small opening for the wick and flame
If you're looking for a quick and easy way to fix candle tunneling, consider using aluminium foil. This method is popular among candle enthusiasts as it is simple and effective. Here's how to do it:
First, cut or tear off a piece of aluminium foil and wrap it around the top of your candle. Make sure the candle is in a jar or container. Create a dome-like structure with the foil, ensuring it covers the top of the candle and extends slightly down the sides. This will help keep the heat in. Then, cut or fold a small opening in the centre of the aluminium foil, about one inch in diameter. This opening is crucial for the wick and flame to receive oxygen and stay lit.
Once you've prepared the foil cover, remove it temporarily and light the wick of your candle. Place the foil cover back on, ensuring the flame is still burning. Allow the candle to burn for a few hours. The foil will help retain the heat, causing the excess wax around the wick to melt and smooth over. This process is sometimes referred to as "resetting the memory" of the wax.
If your flame goes out when you put the foil on, it means the opening you created is too small. Simply widen the hole a little and try again until your flame stays lit. After a few hours, you should see the wax on the top surface of the candle melted and smoothed over. At this point, remove the foil cover and set your candle aside to let the wax harden. This process may take a few days to reach full hardness.
Using aluminium foil to cover your candle is a simple and effective way to fix candle tunneling. It helps distribute heat evenly, ensuring that the wax melts uniformly and preventing the formation of a deep tunnel in the centre. While this method may not work for severely tunneled candles, it is a great option for shallow tunneling issues. Remember, always exercise caution when handling lit candles and hot wax.

Melt the wax in a double boiler and slowly pour it back into the candle's container
Candle tunneling is a common issue that occurs when a hole forms down the centre of the candle, leaving unused wax at the edges. This happens when a candle isn't burned long enough during its first few burns, preventing the wax from melting to the edge of the candle container.
To fix a tunneled candle, you can melt the wax in a double boiler and slowly pour it back into the candle container. Here's how to do it:
First, create a double boiler by using a saucepan and a heat-safe glass bowl that fits inside the saucepan. Fill the saucepan with water and place the glass bowl on top. Ensure that the water level is just right so that it does not touch the bowl; it's better if the bowl is heated by steam than by direct contact with water.
Next, place the candle wax in the glass bowl and turn on the heat. Allow the water to boil, and the steam will heat the bowl of wax. Stay near the double boiler at all times for safety. You can also wear eye protection to shield your eyes from any splattering wax.
Once the wax has melted, carefully remove the glass bowl from the saucepan using a potholder. Be cautious not to tilt the bowl to avoid spills. Now, slowly pour the melted wax back into your candle container. You can use a Pyrex glass measuring cup with an integrated handle to make pouring easier and safer.
Let the wax cool and solidify, and you've successfully fixed your tunneled candle! Remember to burn your candle long enough in the future to prevent tunneling and enjoy an even burn.

Push the wax around the edges towards the wick
Pushing the wax around the edges towards the wick is a good way to prevent candle tunnelling. This is because tunnelling occurs when a candle burns down the middle, leaving unmelted wax around the edges. This usually happens when a candle is not burned for long enough during its first few burns.
To prevent tunnelling, it is recommended that each time you light your candle, you let the wax melt to the edge of the container. This is especially important the first time you light a new candle and usually takes 1-2 hours depending on the size of the candle's surface.
If you are unable to push the wax towards the wick and tunnelling has already occurred, you can try the following:
- Using a hairdryer or heat gun to melt and smooth out the wax of a tunnelled candle.
- Wrapping the candle in aluminium foil to reflect heat back down towards the candle's edge to melt the wax.
- Replacing the wick completely.

Use a hair dryer to melt the hardened wax around the edges
If you're looking to salvage a candle that has tunnelled, one option is to use a hair dryer to melt the hardened wax around the edges. This method can reset the memory of the wax, allowing it to widen the melt pool to the edges.
To do this, start by laying out some newspaper around the candle to catch any wax splatters. Ensure you're wearing clothing that can be easily washed in case of wax stains. For protection from any splatters, it's also recommended to wear eye protection.
Next, turn on your hair dryer, setting it to high heat and low speed. Direct the hair dryer at the unmelted edges of the candle, holding it about six inches away from the surface. Continue heating the wax until it softens and the entire top surface has melted and smoothed over. This may take several minutes, depending on the heat of your hair dryer.
After the wax has melted, relight your candle and let it burn for at least 30 minutes or until the tunnelling is no longer visible. Set the candle aside and allow the wax to harden over the next few days. The time it takes for the wax to harden will depend on the type of wax used. For instance, paraffin wax may take two days to harden, while soy or coconut wax can take up to two weeks.

Use a candle warmer to melt the wax without an open flame
Candle tunneling is a common problem that occurs when a candle isn't burned carefully. It is characterised by a hole forming down the centre, leaving unused wax at the edges. This issue can be remedied by melting the outer wax surrounding the tunnel to create an even surface.
A candle warmer can be used to melt the wax without an open flame. Candle warmers are electric devices that distribute scent from a candle without burning the wax. They come in two varieties: top-down and bottom-up. Top-down candle warmers resemble lamps and melt the wax from the top down with a heat source, usually a lightbulb. Bottom-up candle warmers, on the other hand, look like coasters or mini hot plates and melt the wax from the bottom up.
When using a bottom-up candle warmer, it is advisable to start with a smaller candle to ensure that all the wax in the vessel melts completely. In contrast, top-down candle warmers are better suited for larger candles as they will not melt the wax all the way through. Instead, they slowly melt the wax pool from the top.
It is important to note that candle warmers are size-limited, so they may not be suitable for large candles. Additionally, the fragrance life of a candle when using a warmer depends on the type of wax and fragrance oils used. Once the wax has been warmed to the point that it no longer produces a fragrance, it is necessary to remove the wax and start warming the next layer.
