Candle tunneling is a common issue that occurs when a candle burns down the middle, leaving unburned wax around the edges. This problem can be frustrating and lead to wax wastage. It is usually caused by an inadequate first burn or a wick that is too small. There are several ways to reverse candle tunneling, including using a hairdryer to melt the wax evenly, wrapping aluminum foil around the candle to increase heat, and re-pooling the wax by heating it in an oven. Preventative measures, such as proper wick trimming and ensuring an even melt pool during the first burn, can also help avoid tunneling.
How to Reverse Candle Tunneling
| Characteristics | Values |
|---|---|
| Prevention | Allow candles to burn for 1 hour per inch in diameter, or 3-4 hours for the first use so that the wax melts evenly. |

What You'll Learn
Using a hairdryer to melt the surface of the candle
Candle tunneling is a common issue that can ruin the appearance and reduce the burn time of your candle. It occurs when a candle burns down its centre, leaving hard wax around the outside. This results in an uneven melt pool, which can cause the wick to "drown" and the candle to eventually become impossible to light.
One way to fix minor tunneling is to use a hairdryer to melt the surface of the candle. First, ensure that the candle is extinguished. Then, use the hairdryer on a low setting to carefully melt the wax to the edge of the container. Hold the hairdryer far enough away from the candle to avoid spattering any wax. This process may take some time, as hairdryers do not get extremely hot. The goal is to remove the "memory" of the wax, so that the next time you light the candle, it will burn evenly and form a complete melt pool.
It is important to note that this method is best used for minor tunneling. If your candle is showing more serious signs of tunneling, you may need to try a different method, such as using aluminium foil to reflect heat back to the candle's edge and aid in melting the wax.
Additionally, proper burning during the first use is key to preventing candle tunneling. It is recommended that you allow the candle to burn for long enough during its first use to melt the entire top layer of wax from edge to edge. This usually takes between one to two hours, depending on the size of the candle.

Wrapping aluminium foil around the candle
Wrapping aluminium foil around a candle is a simple yet effective method to prevent tunneling and promote an even burn. Firstly, cut a strip of aluminium foil and wrap it around the top of the candle, creating a snug "hat". Ensure that the foil reaches over the tunneled wax and leave a small opening in the centre for the wick to peek through.
The foil acts as a heat reflector, distributing heat evenly throughout the wax. This will allow the candle to melt uniformly, eliminating tunneling and ensuring that no wax goes to waste. The foil will also prevent the flame from getting too close to the container's sides, reducing the risk of accidents.
However, it is important to note that the foil method may not work for all candles. The quality of the wax and the shape of the container might affect how well the foil hack works. For example, the hack works better with smaller candles, as larger candles may not generate enough heat to melt the wax. Additionally, make sure that the flame can still burn strongly and create enough heat to melt the wax. The opening in the centre of the foil should be large enough to allow plenty of oxygen in as it burns.
While the foil trick is a useful method to reverse tunneling, there are other methods to consider as well. One method is to use a hair dryer or heat gun to melt and smooth out the wax of a tunneled candle. Another method is to let your candle burn for 1 hour per inch in diameter, allowing the wax to melt all the way across the edge of the container. This will create a flat surface on the top layer and prevent tunneling.

Replacing the wick
If your candle has tunnelled far down, you may need to replace the wick. Here's how to do it:
Firstly, you will need to remove the wax around the wick. You can do this by pushing an apple corer through the wax around the wick, then twisting and pulling upwards until the wax plug comes out with the wick. If the wick is still stuck to the bottom of the candle jar, use a pair of needle-nose pliers to pull out the wick tab and wick.
Next, you will need to create a hole for the replacement wick. You can do this by using a toothpick or skewer to poke a hole in the wax. Don't worry about gaps between the wick and the wax, as these areas will fill back in with liquid wax once the candle is re-lit.
If your replacement wick has a tab, you may need to cut it off if it is too long. Since your replacement wick won't have a tab, it may eventually tip over when the candle reaches the end of its life. However, this shouldn't take much time off the life of the candle, and it's better than never burning the candle again!
You can usually buy wicks from your local hobby store, but there's no guarantee they'll be the right size for your candle. Remember to trim your wicks regularly to prevent tunnelling in the future.

Removing wax around the wick
Candle tunneling is a common issue that occurs when a candle burns down the middle, leaving unburned wax around the edges. This results in a deeper hole around the wick, causing the flame to burrow into the wax and leading to wax wastage.
To reverse candle tunneling and remove wax around the wick, you can try the following methods:
The Hair Dryer Method
First, trim the wick and remove any debris from the surface. Set your hair dryer to the lowest setting and direct the hot air towards the uneven sides of the candle. Gradually increase the heat setting and continue heating until the entire surface melts. Then, light the candle and let it burn for at least 30 minutes before blowing it out. Allow the wax to harden for a couple of days before burning it again.
Aluminum Foil Method
Wrap a piece of aluminum foil around the top of the candle, leaving a small opening for the wick and flame. This increases the heat while keeping the vessel insulated, causing the excess wax to melt.
Oven Method
Place the candle container in the oven at a low temperature, usually about 200°F or 93°C, for 20 minutes or until the entire surface of the candle is liquid and appears flat.
Wick Replacement
If the tunneling is too deep or the wick is completely covered in wax, you may need to replace the wick. Remove the wax around the wick using a spoon or a paper towel, or by pushing an apple corer through the wax and pulling it upwards. Then, insert a new wick of the appropriate size.
Preventative Measures
To prevent candle tunneling, ensure that you burn your candle long enough during its first use, typically 1 hour per inch in diameter. This allows the wax to melt evenly across the surface. Regularly trim the wick to the recommended length of about 1/4 inch and keep the candle away from drafts.

Using a candle topper
Candle tunneling is a common problem that can be frustrating to deal with. It occurs when only the middle part of the candle around the wick melts, leaving a hard ring of wax around the edge. This results in an uneven burn, reduced burn time, and a decrease in the scent throw.
To use a candle topper, simply place it on top of your candle, ensuring it covers the entire surface of the wax. Then, light your candle as you normally would and let it burn for a few hours. As the candle burns, the topper will distribute the heat evenly, preventing tunneling and promoting a more uniform burn. Candle toppers are especially useful for larger candles with a single wick.
In addition to their functionality, candle toppers also come in unique and intricate designs, adding a decorative touch to your candles. They can be swapped out seasonally or changed to match your decor. Candle toppers are a great accessory to enhance the burning experience and prevent the annoyance of candle tunneling.
By using a candle topper, you can maintain an even burn and prevent tunneling. It is a simple yet effective solution that not only improves the performance of your candles but also adds a stylish element to your space.
