Candle tunneling is when a candle burns down its centre, leaving hard wax around the outside. This not only looks unsightly but also reduces the candle's burn time and scent potential. Tunneling can be caused by a number of factors, including an improperly sized wick, ingredients clogging the wick, or a strong airflow. To fix a tunneling candle, you can try the foil trick, which involves covering the top of the candle with aluminium foil and lighting the wick, allowing the flame to work harder and melt the surrounding wax. Alternatively, you can use a hair dryer to melt the wax around the edges and create an even surface.

Use a hair dryer to fix minor tunneling
If you notice candle tunneling starting to occur, you can use a hair dryer to fix minor tunneling. Candle tunneling happens when a candle burns down its center, leaving hard wax around the outside. This can be caused by not allowing the wax to melt to the edge of the candle during its first burn.
To fix minor tunneling with a hair dryer, first extinguish the candle flame. Then, use a hair dryer on a high heat setting to melt the wax to the edge of the container. Ensure that you hold the hair dryer far enough away from the candle to avoid spattering hot wax. The goal is to remove the "memory" of the wax buildup so that the next time you light the candle, the pool of melted wax will reach the edge of the container.
While this method can be an effective quick fix, it is important to note that it is only a temporary solution. The tunneling may reoccur the next time the candle is lit, and you may need to repeat the process. Additionally, some people have expressed concerns about using a hair dryer with a candle, as it may cause the wicks to drift too close to the edge and potentially damage the container.
Overall, while using a hair dryer can be a convenient way to fix minor candle tunneling, it may not be a long-term solution, and it is important to exercise caution to avoid any potential risks.

Try the foil method for more serious holes
If your candle is showing more serious signs of tunneling, it's time to try the foil method. This is a relatively easy method to fix candle tunneling. Firstly, trim the wick and remove any debris inside the tunnel. Then, cover the top of the candle with a piece of aluminum foil, leaving a small opening for the wick and flame. This can be done by cutting or folding a small opening of about 1 inch in the center of the foil.
Remove the foil cover, light the wick, then place the foil cover back on. Allow the candle to burn for a few hours until the top surface of wax has completely melted and smoothed over. Set your candle aside and let the wax harden over the next few days to reach full hardness. This step is pivotal for the resetting process, ensuring a smooth surface for subsequent burns.
The foil method works by concentrating the flame's heat, thwarting future tunneling. It increases the heat while keeping the vessel insulated, causing the excess wax to melt. This is a popular trick among candle lovers.

Prevent tunneling by burning your candle long enough
Candle tunneling is when a candle burns down its centre, leaving hard wax around the outside. This can be unsightly and also means you're missing out on the full burning and scent potential of your candle.
Tunneling happens when a candle isn't burned long enough during its first few burns. This prevents an initial layer of wax from melting to the edge of the candle container. When your candle doesn't burn evenly, it can cause tunneling.
To prevent tunneling, burn your candle long enough each time so that the entire top surface of wax is melted. The average burn time for the first use should be anywhere between one to four hours, depending on the size of the candle. If it's a candle with a diameter of one inch, burn it for about one hour. If it burns for longer than that, it can overheat and the candle glass may crack.
If you forgot to let the wax pool reach the edge on the first burn, you can try a quick fix: use a hairdryer to melt the wax around the edges and smooth the surface. If your candle is showing more serious signs of tunneling, wrap a piece of aluminum foil over 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.

Trim the wick and remove debris
Trimming the wick and removing debris is an important step in preventing candle tunneling. Candle tunneling occurs when only a small portion of the wax surrounding the wick melts while the candle is lit, resulting in a vertical tunnel in the centre of the candle with unburned wax lining the walls.
To prevent this, it is important to trim the wick to about a quarter of an inch before each burn. This helps to prevent debris from falling into the wax and clogging the wick, which can cause the candle to burn unevenly and create smoke and soot. It is also crucial to remove any debris inside the tunnel, as this can affect the candle's ability to burn evenly.
If your candle has already started to tunnel, you can try the foil trick. Cover the top of the candle with aluminium foil, leaving a small opening for the wick and flame. This increases the heat while keeping the vessel insulated, causing the excess wax to melt and helping to "reset the memory" of the wax.
Another way to fix candle tunneling is to gently remove the higher wax along the edges with a butter knife or spoon, making sure not to damage the wick or container. If your wick is too short, you can dig around to expose it and ensure it is the adequate length for a proper burn.
By regularly trimming the wick, removing debris, and taking corrective measures when necessary, you can help prevent candle tunneling and ensure your candles burn evenly and efficiently.

Remove wax around the wick
Candle tunneling is a common problem that occurs when a candle burns down the middle, leaving a wall of unmelted wax around the inside of the candle jar. This usually happens when a new candle hasn't burned long enough during its first use, creating a "memory ring" or \"memory\" that persists in subsequent burns. To fix this issue, you can try the following methods:
Using a Hair Dryer
One way to fix minor tunneling is to use a hair dryer to melt the top layer of wax and create an even surface. Ensure that you extinguish the candle's flame before starting. Hold the hair dryer on a medium or high heat setting over the top of the candle until the wax has melted and smoothed. Be careful not to overheat the wax to prevent any damage.
The Foil Method
For more serious tunneling, you can use the foil method to reflect heat back to the candle's edge and aid in melting the wax. Wrap aluminum foil around the outside of the candle, ensuring that it reaches over the unmelted wax and leaves a window for the wick. This technique helps the flame work harder by concentrating its heat. After achieving an even surface, let the wax cool and solidify before relighting the candle.
Scooping Out the Wax
Another method involves scooping out the unmelted wax with a spoon until it is level with the melted wax in the middle. Be sure to dispose of the wax in a waste bin to avoid clogging drains. Once the wax is level, light the candle and allow it to burn until the pool of melted wax reaches the edge of the container.
Replacing the Wick
If the tunneling is too deep or the wick is completely covered in wax, you may need to replace the wick. Use an apple corer to push through the wax around the wick, then twist and carefully pull upwards to remove the wax plug and wick. If the wick is stuck, use needle-nose pliers to detach it from the bottom of the jar.
Remember, the best way to address candle tunneling is to prevent it from occurring in the first place. Always ensure that your candle burns long enough during its first use to create an even wax pool that reaches the edge of the container. Additionally, maintain the wick by trimming it regularly and keeping it centred to promote an even burn.

Frequently asked questions
Candle tunneling occurs when a candle burns down its centre, leaving hard wax around the outside. This can reduce the burn time and scent of the candle.
Tunneling can occur if the wick is too small for the size of the vessel, or if there are ingredients clogging the wick, causing a low burn. It can also be caused by a strong airflow, which moves the flame around.
To prevent tunneling, burn your candle long enough for the entire top surface of wax to melt. The average burn time for the first use should be between one and four hours, depending on the candle size.
You can try the foil trick: cover the top of the candle with aluminium foil, leaving a small opening for the wick and flame. This increases the heat while keeping the vessel insulated, causing the excess wax to melt. Alternatively, you can use a hair dryer on high heat to melt the wax around the edges.
If the sinkhole is 1-2 inches deep, it may be difficult to salvage the candle. You may need to melt down and remove the extra wax. If the wick is "drowning" in wax, you can gently remove the wax around the wick to expose about 1/4 inch of unburnt wick.
