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, creating a candle memory that causes the wax to melt at different rates and results in a tunnel forming with each subsequent burn. This guide will provide simple tricks to fix candle tunneling and prevent it from happening in the future.

What You'll Learn
Trim the wick to 1/4-1/8 inch
Trimming the wick is an important part of candle care. It is recommended to trim the wick to 1/4-1/8 inch in height. This is because if the wick is too short, it might not be able to generate enough heat to melt the wax at the edge of the candle. This can cause candle tunneling, where a hole forms down the center, leaving unused wax at the edges.
If your wick is too short, you can pour out some of the wax until there is about 1/8 to 1/4 inch of wick above the surface. You can also use a paper towel to soak up the excess wax. After trimming the wick, light the candle and allow it to burn for 30 minutes to a few hours, depending on the size of the candle, until the wax has melted evenly.
If your candle has already started tunneling, you can try to fix it by melting the outer wax surrounding the tunnel to create an even surface. This can be done with a hair dryer or by placing the candle in a low oven until the wax has melted. Another method is to use aluminum foil to reflect the candle's heat and melt the extra wax. Cut a small opening in the center of the foil and place it over the candle, then light the wick and allow the candle to burn for a few hours until the wax has melted evenly.
To prevent candle tunneling in the future, make sure to trim the wick regularly and burn the candle for long enough on the first burn to allow the wax to melt evenly.

Burn for 1-4 hours first time
When lighting a candle for the first time, it is important to allow it to burn for a sufficient amount of time to ensure that the wax melts evenly across the surface. This is crucial to prevent candle tunneling, which occurs when a candle burns down the middle, leaving thick wax walls around the edges.
To avoid this issue, burn your candle for 1-4 hours during its first use. This will create a large enough melt pool to ensure the candle burns evenly in the future. The ideal melt pool diameter is about 1/4th of an inch for each inch of the candle's diameter. For example, if your candle is 4 inches in diameter, you should aim for a 1-inch wax melt pool all the way around.
Burning your candle for a shorter duration may not provide enough time for the wax to melt to the edges, resulting in tunneling. On the other hand, burning it for too long can be dangerous and may cause the wick to move, leading to uneven burning.
Additionally, before relighting your candle, trim the wick to about 1/4th of an inch. This helps prevent the flame from becoming too large and creating soot, and it also ensures a cleaner and more even burn.

Melt wax with a hairdryer
If your candle has started to tunnel, it can be disappointing as it means you're not getting the best performance from your candle. Candle tunneling is when only a small circle of wax melts around the wick, instead of the entire surface of the candle. This results in wasted wax and reduced burn time.
One way to fix candle tunneling is to melt the wax with a hairdryer. First, extinguish the flame if it is lit. Then, use a hairdryer to melt the wax to the edge of the container. It is recommended to use a low setting and hold the hairdryer far enough away to avoid spattering any wax. This method works best if the tunneling is not too severe and has just begun, as it may take a few tries to melt the wax evenly.
The hairdryer method is a quick fix to remove the "memory" of the wax, which is when previously melted wax takes less heat to re-melt, resulting in wax melting at different rates and causing the tunneling effect. By melting the entire surface of the wax, you can remove this memory and allow the candle to burn more evenly the next time it is lit.
It is important to note that the hairdryer method is a temporary solution, as the candle may tunnel again the next time it is lit. To prevent tunneling, it is recommended to allow the candle to burn long enough for the wax to melt to the edge of the container, especially during the first use. Additionally, proper wick care is important, including trimming the wick to 1/4 inch before each lighting to enable a cleaner, more consistent burn.

Use aluminium foil to trap heat
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 is not burned carefully, or the wick is too small, preventing the wax at the edges from melting.
One way to fix this issue is by using aluminium foil to trap heat and reflect it back onto the candle. This method helps to melt the wax evenly, eliminating tunneling and preventing wax wastage.
To use this method, start by trimming the wick and removing any debris inside the tunnel. Cut or fold a small opening (approximately 1 inch) in the centre of a sheet of aluminium foil. Place the foil over the top of the candle, ensuring it covers the jar and slightly overlaps the top to trap heat inside. Light the candle as usual and allow it to burn for a few hours. The flame's heat will be reflected by the foil, melting the wax uniformly and smoothing over any tunneling.
It is important to note that the foil will get hot, so be careful when adjusting or removing it. Additionally, always prioritise safety when dealing with lit candles and hot wax.
The aluminium foil trick is a simple and effective way to fix candle tunneling and promote an even burn. It helps to distribute heat evenly, ensuring that your candle burns brightly and beautifully.

Remove wax with a spoon
Candle tunneling is a common problem that occurs when a candle isn't burned carefully. It happens when a hole forms down the centre, leaving unused wax at the edges. This can be caused by a wick that is too small, or a first lighting that is too brief.
One way to fix this issue is to remove the excess wax with a spoon. Here is a step-by-step guide:
Firstly, ensure your candle has been extinguished and that the wax has hardened. Depending on the type of wax, this can take between two days and two weeks.
Next, take a spoon and gently scrape away the unburned wax around the edges, being careful not to damage the wick or container. Remove wax until the surface is level and even.
Once you have removed the excess wax, you may need to expose more of the wick. If the wick is "drowning" in wax, use your spoon to gently remove the wax around it, exposing about a quarter of an inch of unburnt wick.
Now that you have removed the excess wax, you can relight your candle and allow it to burn for at least 30 minutes, or until the tunneling is no longer visible.
Finally, dispose of the wax in a waste bin. Do not pour wax down the drain, as it can cause clogging.

Frequently asked questions
Candle tunneling is a common problem 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, creating a "'memory'" that prevents an initial layer of wax from melting to the edge of the candle container.
To prevent candle tunneling, ensure that you burn your candle long enough for the wax to melt completely from the wick to the edge of the container. You should also trim the wick to 1/4 to 1/8 of an inch before each burn to prevent debris from getting into the wax.
There are several ways to fix candle tunneling, including:
- Using a hairdryer to melt the wax to the edge of the container.
- Wrapping aluminium foil around the candle to trap and reflect heat, thereby melting the wax.
- Scooping out the unmelted wax with a spoon to remove the "memory".
