A candle that keeps going out may be suffering from candle tunneling, a common issue that occurs when a candle isn't burned carefully. This results in a hole forming down the candle's centre, leaving unused wax at the edges. Candle tunneling can drastically reduce the total burn time of your candle, as the wick descends deeper into the surrounding wax, and the flame can’t get enough oxygen to sustain itself. To fix this issue, you can use a hair dryer to melt the wax to the edge of the container, wrap aluminium foil around the outside of the candle to reflect heat back down, trim the wick, or melt the wax around the wick with a match or lighter and then dab away the excess.

What You'll Learn
Remove charred wood from the wick
If your candle keeps going out, it may be due to a phenomenon known as "candle tunneling". This is when a hole forms down the candle's centre, leaving unused wax at the edges. Tunneling occurs when only a small portion of the wax surrounding the wick melts while the candle is lit, causing the wax to melt down into the wick faster than the wick can burn it. This results in the flame being extinguished.
To fix this issue, you should trim your wick to about 1/4" or 6mm above the surface of the wax. You can use nail clippers to trim the wick just above the char line. Remove any charred wood from the wick before lighting the candle again. This will ensure that the flame is not "drowning" in its wax pool.
If your candle has already tunneled, you may need to level the wax. You can do this by melting the wax with a hair dryer or by placing the candle in a wax warmer. You can also use a spoon or a wick dipper to carefully remove the outer rings of wax, creating a more level surface.
Once you have trimmed the wick and removed any charred wood, relight the candle and let it burn until an even wax pool forms all the way to the edge of the jar. This may take a while, so be patient and let the wax continue to melt. You can also use foil to wrap around the outside of the candle, with a bit of foil extending inward over the unmelted wax. This will reflect the heat and help melt the wax evenly.

Melt wax around the wick with a lighter
If your candle keeps going out, it may be experiencing tunnelling. This is when a hole forms down the centre of the candle, leaving unused wax at the edges. This can happen when a candle is not burned long enough for the wax to melt to the edges, creating a memory barrier that prevents the wax outside the tunnel from melting in future burns.
To fix this, you can melt the wax around the wick with a lighter. First, extinguish the flame if it is lit. Then, hold the lighter above the wax around the wick and let the wax melt. You can also use a hair dryer on a low setting for this step, but be careful not to hold it too close to the wax to avoid spattering.
Once the wax has melted, use a paper towel or napkin to dab away or drain any excess wax from around the wick. This will give the wick more space to burn and prevent the flame from drowning in its own wax pool. If needed, repeat the process until the wick has enough room to stay lit.
After removing excess wax, relight the candle and let it burn until the wax melts to the edges of the jar. This will reset the memory of the wax and help to prevent future tunnelling. Depending on the severity of the tunnelling, the flame may vary, but as long as it is burning, the process is working.

Prevent candle tunneling by burning the candle long enough
Candle tunneling is a common issue that occurs when a candle is not burned properly. It happens when a hole forms down the centre of the candle, leaving unused wax at the edges. This problem can reduce the total burn time of your candle and waste wax.
To prevent candle tunneling, it is important to burn your candle long enough for the entire top surface of wax to melt. This is especially important the first time you burn your candle. The amount of time this takes depends on the size of the candle. A good rule of thumb is to burn your candle for one hour per inch of its diameter. For example, if your candle has a diameter of 3 inches, you should let it burn for 3 hours. This will prevent the wax from creating a tunnel and burning downwards, prolonging the life of your candle.
If you are unable to burn your candle for long enough to melt the entire top surface of wax, you can try using aluminium foil to reflect heat back down to the candle's edge and aid in melting the wax. Wrap the foil around the outside of the candle, leaving the centre open for the flame. After 1-2 hours of burning, the surface of the candle should even out, and you can remove the foil.
By following these simple steps, you can prevent candle tunneling and ensure that your candles burn evenly and efficiently.

Trim the wick to 1/4 or 6mm above the wax surface
If your candle keeps going out, it may be due to a problem called candle tunnelling. This is when a hole forms down the centre of the candle, leaving unused wax at the edges. Candle tunnelling occurs when only a small circle of wax around the wick melts while the candle is burning, instead of the wax melting evenly across the surface.
To fix this issue, you should trim the wick to 1/4 inch or 6mm above the wax surface. This may seem counterintuitive, but it is the wax that fuels the flame, not the wick. Trimming the wick ensures that the wax can reach the flame. If the wick is too long, the wax will not be able to travel up through the wick, causing the flame to be extinguished.
To trim the wick, use nail clippers to cut it just above the char line. Then, relight the candle and let it burn until an even wax pool forms, reaching the edges of the jar. This may take some time, so be patient and let the wax continue to melt.
In addition to trimming the wick, you can also use foil to help fix candle tunnelling. Wrap the foil around the outside of the candle, extending it slightly over the top to reflect the heat and help melt the wax evenly.

Use foil to reflect heat and melt wax evenly
If your candle keeps going out, it may be due to a phenomenon called "candle tunneling". This occurs when a candle isn't burned long enough, creating a hole down the center of the candle and leaving unused wax at the edges. To fix this issue, you can use foil to reflect heat and melt the wax evenly.
Here's how to do it:
- Start by extinguishing the flame if your candle is currently lit.
- Take a sheet of aluminum foil and wrap it around the outside of the candle. Ensure that the top of the foil extends inward over the unmelted wax, creating a roof-like structure while leaving the center open for the flame.
- Light the candle and let it burn for 1-2 hours. The foil will reflect the heat back down to the candle's edge, aiding in melting the wax evenly.
- Carefully remove the foil once it has cooled down. The surface of your candle should now be even, with a pool of melted wax reaching the edge of the container.
It may take a few tries to get it right, so be patient and cautious when handling the foil as it will get hot. Additionally, if your flame goes out when you place the foil on, try widening the opening slightly to ensure proper airflow and ventilation for the flame.

Frequently asked questions
Your candle may be going out due to a phenomenon called "candle tunneling", where a hole forms down the candle's centre, leaving unused wax at the edges. To fix this, use a spoon or a wick dipper to carefully remove the outer rings of wax, creating a more level surface. Trim the wick just above the char line, then re-light and let it burn until an even wax pool forms.
Candle tunneling is often caused by a candle that is lit for too short a time, preventing the melted wax from reaching the edge of the candle. This creates a barrier that remains in subsequent lightings.
To prevent candle tunneling, burn your candle long enough for the entire surface of the wax to melt before blowing or snuffing it out. This usually takes at least an hour or two, depending on the size of the candle. A good rule of thumb is to burn your candle for one hour per inch of its diameter.
