Candle tunneling, or uneven wax melt, is a common issue that occurs when only the center of the wax melts, leaving a thick ring of unmelted wax around the edges. This problem can be caused by an initial burn that is too short, a wick that is too small, or an off-center wick. Luckily, there are several ways to fix a tunneling candle and prevent wax wastage, with one of the most popular methods being the use of aluminum foil.

Cover the candle with foil, leaving a small opening for the wick and flame
Candle tunneling is a common issue that occurs when the wick burns straight down the center, leaving a thick ring of unmelted wax around the edges. This can be caused by not letting a candle burn long enough during its first use, an insufficiently large wick, or an off-center wick.
To fix a tunneling candle with foil, you can wrap a piece of aluminum foil around the top of the candle, creating a dome-like structure. Ensure that the foil covers the tunneled edges but leaves a small opening at the top for the wick and flame to burn properly and for air to flow. The foil increases the heat while keeping the vessel insulated, causing the excess wax to melt.
After lighting the candle, let it burn for a few hours. The heat trapped by the foil will help melt the outer wax, evening out the wax pool. Keep an eye on the candle and adjust the foil if necessary to prevent overheating. Once the wax has melted evenly, remove the foil.
It is important to note that the foil method may not work for all candles, especially larger ones with wider jars. For larger candles, ensure that the flame can still burn strongly and create enough heat to melt the wax. The opening in the center of the foil should be large enough to allow plenty of oxygen in as it burns.
To prevent candle tunneling in the future, consider buying candles with multiple wicks and letting them burn for several hours the first time you light them. Additionally, remember to trim your wicks regularly and keep candles away from drafty windows.

Use a hairdryer to melt the wax
Using a hairdryer is an effective way to fix a tunneling candle and melt the wax. Firstly, ensure that you lay down newspaper or another type of covering around the candle to catch any wax splatters. Then, if the candle is lit, extinguish the flame. Set your hairdryer to its highest heat setting and lowest speed setting. Hold the hairdryer about six inches away from the candle and direct the heat at the unmelted edges of the candle until the wax softens and settles into a flat surface. Be careful not to overheat the wax, as this could cause damage. You may need to hold the hairdryer steady for up to 5 minutes, so make sure you are sitting down.
This method works to remove the "memory" of the candle, which is when the wax remembers its previous melt and fails to melt evenly in subsequent lightings. By melting the entire candle surface with a hairdryer, you can reset the candle and ensure that the wax melts evenly in the future.

Put the candle in the oven
If you're looking for an alternative to the aluminium foil method, you can put your candle in the oven to fix tunneling. This method is also a good option if you're concerned about the foil method drowning your wick.
Firstly, place your tunneling candles on a baking tray. You can optionally cover the top of the candle with aluminum foil to prevent direct heat exposure. Put the tray in the oven for around 5-10 minutes, keeping a close eye on the candles. The exact time will depend on the size of your candle and the power of your oven, but you should remove the candles from the oven once the wax has melted and evened out.
Let the candles cool completely, then trim the wick to the appropriate length before relighting. Remember to always follow safety precautions when handling hot wax and using the oven.
To prevent candle tunneling in the first place, it's important to allow your candle to burn long enough during its first use to create a full melt pool that reaches the edges of the container. This will help the candle burn evenly in the future. It's also a good idea to keep your wick trimmed to 1/4 inch before each burn to ensure a steady and even flame.

Trim the wick
Trimming the wick of a candle is an important step in candle care. It ensures a clean burn and reduces the amount of soot produced by the candle. By trimming the wick, you can also prevent the candle from burning too hot and fast, which can cause the wax to tunnel and leave black smoke stains on the candle vessel and surrounding areas.
To trim the wick, use a wick trimmer, scissors, nail clippers, or even your fingertips to cut the wick to the recommended height. The ideal height for a wick varies depending on the type of wick and wax blend, but the general recommendation is to keep the wick between 1/4 inch and 1/2 inch tall. Wooden wicks, for example, are typically trimmed to 1/2 inch, while cotton wicks can be shorter at 1/4 inch. Trimming the wick to the appropriate height will help maintain a healthy flame height and prevent the wick from burning too hot.
It is recommended to trim the wick before lighting the candle. This is because the wax is still solid, making it easier to trim. However, you can also trim the wick while the candle is lit if you notice the flame is too tall. Simply extinguish the flame, let the candle cool down, and then trim the wick to the desired height. Be careful not to trim the wick too short, as this can make it difficult to light. If you accidentally trim the wick too short, you can use a heat gun or hair dryer to melt the wax around the wick and correct the issue.
Wick trimmers are specifically designed for trimming candle wicks and are the easiest and cleanest option. They have long handles to reach into deep candle jars and tray-shaped blades to catch the wick debris, preventing it from falling into the wax. If you don't have a wick trimmer, scissors can be used, especially for cotton wicks. However, scissors may not be able to cut through wooden wicks, and the burnt wick debris may fall into the wax.
Trimming the wick of your candle is a quick and easy task that can significantly improve the burning experience and extend the life of your candle. It is recommended to trim the wick regularly, especially if you burn your candles for long periods. By incorporating wick trimming into your candle care routine, you can enjoy a cleaner, safer, and more enjoyable burn.

Use a candle topper
Candle tunneling, or uneven wax melt, is a common issue that occurs when the wick burns down the centre of the candle, leaving a thick ring of unmelted wax around the edges. This issue can be caused by an initial burn that was not long enough, a wick that is too small, or an off-centre wick.
A candle topper is an effective way to fix tunneling and prevent it from occurring in the future. Candle toppers are open metal lids that often feature intricate designs. They are placed on top of the candle to protect the flame from wind and drafts, ensuring the wax melts evenly. They are most effective on larger candles with a single wick.
To use a candle topper, simply place it on top of the candle before lighting the wick. The topper will help to distribute heat evenly, melting the wax at the edges of the candle. It is important to ensure that the candle topper is large enough to allow for adequate airflow and oxygen supply to the flame.
Candle toppers are a great way to add a decorative touch to your candles while also ensuring an even burn. They are typically available in various designs, allowing you to choose a style that suits your taste and décor.
In addition to using a candle topper, there are other methods to fix candle tunneling. One popular method is the aluminum foil method, which involves wrapping foil around the top of the candle to trap heat and melt the wax evenly.

Candle tunneling occurs when the wick burns straight down the center, leaving a thick ring of unmelted wax around the edges. To fix this with foil, cut a piece of aluminum foil to cover the top of the candle, ensuring the foil covers the tunneled edges but leaves an opening at the top for air to flow and the flame to burn. Light the candle and let it burn for a few hours. The heat trapped by the foil will melt the outer wax, creating an even wax pool.
Candle tunneling is usually caused when a candle is not allowed to burn long enough during its first use. To prevent this, ensure your candle burns for long enough to create a full melt pool that reaches the edges of the container. It is recommended to burn the candle for one hour per inch of diameter each time you light it.
Aside from the foil method, you can use a hairdryer to gently warm the top layer of the candle until the wax melts evenly. You can also use a spoon to smooth out the surface if needed. Another method is to gently remove the higher wax along the edges. This works well if the wick is "drowning" in wax.
