Candle tunneling is a common problem that occurs when a candle burns down the centre, leaving unmelted wax around the edges. This issue can reduce the burn time of your candle and create an uneven, unattractive appearance. While tunneling can occur for various reasons, it is often due to an insufficiently long initial burn, allowing the wax to solidify before it has a chance to melt evenly. This creates a 'memory' in the wax, making it more difficult to achieve an even melt in subsequent burns. However, there are several ways to rescue a tunneled candle and restore its even burn.

What You'll Learn
Using aluminium foil to reflect heat
To use the aluminium foil trick, light your candle as usual. Tear off a piece of aluminium foil and wrap it around the top of the candle, creating a tent or dome that covers the unmelted wax. Make sure the foil fits snugly against the sides, leaving only a small hole in the centre for the wick and flame to breathe. The foil should be higher than the wax level to prevent any overflow during the next burning session.
The foil traps and reflects the heat inward, encouraging the outer wax to melt and level out with the centre. Carefully remove the foil once the wax pool reaches the edges. This trick works best when tunnelling is still shallow and the wick is accessible. Always monitor your candle while using this method, as the container and foil will get hot.
While the aluminium foil trick is a simple and effective way to fix candle tunnelling, it is important to note that it may not work for all candles. The quality of the wax and the shape of the container may affect how well the foil hack works. For larger candles, make sure the flame can still burn strongly and create enough heat to melt the wax.

Melting the candle's surface with a hair dryer
Candle tunnelling 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 an initial layer of wax from melting to the edge of the candle container.
To fix this issue, you can melt the entire candle surface with a hair dryer. Firstly, extinguish the flame if it is lit. Then, turn on your hair dryer and hold it far away from the candle, slowly moving it closer until you reach an appropriate distance. Set your hair dryer to low speed and high heat. Continue heating the candle until the entire top surface of wax has completely melted and smoothed over. You can use a spoon to smooth out the surface if needed.
Be careful not to overheat the candle, to prevent any damage. This process may take several minutes, depending on how hot your hair dryer gets, so patience is key. Once the wax has melted evenly, relight your candle and let it burn for at least 30 minutes or until you can no longer see any tunnelling. Finally, set your candle aside and let the wax harden over the next few days.

Trimming the wick
The optimal length for a candle wick is about a quarter of an inch. If the wick is too short, it may not be able to generate enough heat to melt the wax all the way to the edge of the candle, which can cause tunneling. However, if the wick is too long, it can create a larger flame that may be a fire hazard.
It is also important to ensure that the wick is centred. If the wick is off-centre, it can cause the wax to melt unevenly, leading to tunneling. Gently digging around the wax with a spoon or knife can help to expose the wick and ensure it is centred.
By trimming the wick and ensuring it is the correct length and position, you can help to prevent tunneling and promote an even, clean burn.

Using a candle topper
Candle toppers are usually made of metal and come in various intricate and cute designs, serving as decorative accessories for your candles. They can be swapped out seasonally or changed to match your decor.
To use a candle topper, simply place it on top of the candle vessel after lighting the candle. The topper will protect the flame from wind and drafts, helping the candle burn evenly.
It is important to note that candle toppers work best on larger candles with a single wick. If your candle has multiple wicks, consider using other methods such as the aluminium foil trick to fix tunnelling.
By using a candle topper, you can not only rescue a tunnelled candle but also enhance the overall aesthetic appeal of your candle display.

Scooping out wax with a spoon
It's important to note that this method may result in some wax wastage and a potential reduction in burn time. However, it is a quick and easy way to fix candle tunnelling and ensure a more even burn.
Remember to always exercise caution when working with candles. Never leave a burning candle unattended, and be mindful of pets, children, drafts, and anything nearby that could catch fire.
After levelling the wax with a spoon, the next step is to light the candle and let it burn. It is important to allow enough time for the melted wax to reach the edge of the container, which may take an hour or two. This will help prevent further tunnelling and promote an even burn.

Frequently asked questions
Candle tunneling occurs when a candle burns down the centre, leaving unmelted wax around the edges. This typically happens when a candle has not been allowed to burn long enough during its first use.
To prevent candle tunneling, ensure that during the first burn, you allow the candle to burn long enough for the entire surface to melt. This usually takes 1-4 hours depending on the size of the candle. You can also buy candles with multiple wicks, use a candle topper, or trim the wick to 1/4 inch before each burn.
To rescue a tunneled candle, you can use a hairdryer to melt the wax around the edges, or wrap the candle in aluminium foil to reflect heat back down and aid in melting the wax. You can also try scooping out the unmelted wax with a spoon until it is level with the melted wax in the middle.
Candle tunneling can be caused by a wick that is too small, or by a short first burn. It can also be caused by a low-quality candle with poor wax composition, or by drafty conditions.
