An unevenly melted candle is not only an eyesore but also reduces the burn time of your candle. This phenomenon is called candle tunneling, which occurs when only a small circle of wax melts around the wick while the candle is burning, instead of the entire surface melting evenly. Candle tunneling can be caused by a variety of factors, such as a poorly made candle with a wick that is too small or a first lighting that is too brief. Luckily, there are several methods to fix an unevenly melted candle and prevent tunneling in the future.
How to fix an unevenly melted candle:
| Characteristics | Values |
|---|---|
| First Burn | Allow the candle to burn long enough to melt the entire surface of the wax. |
| Wind | Keep the candle away from wind or drafts as they can cause the flame to flicker or bend, resulting in an uneven burn. |
| Hair Dryer | Use a hair dryer to melt the entire surface of the wax until smooth. |
| Foil | Wrap foil around the candle to reflect heat back down and aid in melting the wax. |
| Wick | Trim the wick to 1/4 inch before each lighting to enable a cleaner, more consistent burn. |
| Wax Removal | Scoop out the unmelted wax with a spoon to make the surface even. |
| Wick Surgery | Poke a hole next to the wick and insert a new piece of wick. |

What You'll Learn
Use a hairdryer to melt the wax evenly
If your candle is burning unevenly, it may be due to a phenomenon known as \"candle tunneling". This occurs when a candle burns down its centre, leaving hard wax around the outside. This not only looks unsightly but also reduces the burn time of your candle as it prevents all of the wax from melting.
To fix this issue, you can use a hairdryer to melt the wax evenly:
Firstly, extinguish the candle flame if it is lit. Then, grab your hairdryer and turn it on, adjusting it to a low setting. Start by holding the hairdryer at a distance from the candle to avoid spattering any wax as it melts. You can then gradually move it closer to the candle, focusing the airflow on the top of the candle until the top layer of wax has melted and smoothed out to the edges of the container. This process will \"reset the memory\" of the wax, ensuring that the next time you light your candle, the wax will melt evenly.
It is important to act quickly if you notice candle tunneling. The longer you wait, the deeper the tunnel may become, and the more challenging it will be to salvage your candle. If the sinkhole caused by the tunneling is deeper than one to two inches, it may be difficult to fix, and you may need to spend a significant amount of time melting and removing the excess wax.
While using a hairdryer is an effective method for fixing candle tunneling, there are other techniques you can try as well. One common method is to use aluminium foil to reflect heat back down to the candle's edge, aiding in melting the wax evenly. Additionally, you can try scooping out the unmelted wax with a spoon until it is level with the melted wax in the centre, creating a flat surface for even burning.

Wrap foil around the candle to reflect heat
Wrapping foil around a candle is a common way to fix candle tunnelling, which occurs when only a small circle of wax around the wick melts while the candle is burning, instead of the entire surface. This happens because wax has a "memory", meaning previously melted wax is softer and takes less heat to melt again. As a result, when you relight your candle, the wax melts at different rates, resulting in a tunnelling effect.
To fix this, you can wrap foil around the outside of the candle, ensuring that the top extends inward over the unmelted wax, while leaving the centre open for the flame. The foil reflects heat back down to the candle's edge, helping to melt the wax around the sides. It traps the heat inside, increasing the temperature enough to melt the top layer of wax. This method may take a few tries, and the foil will get hot, so be careful to let it cool before adjusting or removing it.
You can also use a hair dryer to melt the wax to the edge of the container. However, the foil method is a good alternative if you don't have a hair dryer, or if you want to avoid the mess of spattered wax.
It's important to note that the foil method is a temporary fix to melt the wax, and you may need to repeat it a few times. Additionally, some people may not like this method as it covers the candle, obstructing the view of the flame.

Trim the wick to 1/4 inch
Trimming the wick to 1/4 inch is an important step in ensuring a clean, even, and fragrant burn. It is a simple yet effective way to maintain the health of your candle and enhance its performance.
Firstly, trimming the wick helps to control the height of the flame. When the wick is too long, it can lead to a flame that is too large, which increases the risk of a fire hazard. By trimming the wick to 1/4 inch, you can achieve a healthy flame height, typically between 1/2 inch to 1 inch. This ensures a steady burn and proper scent throw, preventing the candle from burning too quickly and prolonging its lifespan.
Secondly, trimming the wick to the recommended length helps to prevent tunneling. Tunneling occurs when the wick is too long, causing the flame to get too hot and burn excess wax. This results in a narrow hole or tunnel forming in the centre of the candle as the wax in the middle gets lower compared to the unmelted wax around the rim. By trimming the wick, you can help maintain a consistent burn and prevent this uneven melting.
Additionally, trimming the wick to 1/4 inch helps to prevent soot buildup. A long wick can cause the candle to burn too hot, leading to the production of soot. Soot buildup can not only damage your candle but also negatively impact your indoor air quality. Trimming the wick to the recommended length keeps the wick from getting too hot, reducing soot formation and keeping your candle and its surroundings clean.
To trim the wick, it is best to use a wick trimmer, which is designed specifically for this purpose. Alternatively, sharp scissors or nail clippers can also be used, cutting the wick vertically and ensuring a straight and even trim. Trimming the wick before lighting the candle is ideal, allowing for a cleaner and safer burn.

Scoop out wax to remove the candle's 'memory'
When a candle burns unevenly, it creates a "tunnel" down the centre, with only a small circle of wax melting around the wick. This phenomenon is called a candle's "
To fix this issue, you can try scooping out the unmelted wax with a spoon until it is the same height or lower than the middle part that melts, thereby removing the "memory". Here is a step-by-step guide:
- Ensure you are mindful of safety precautions: never leave a burning candle unattended, and be cautious of pets, children, drafts, and anything nearby that could catch fire.
- Allow the candle to cool completely before attempting to scoop out the wax.
- Using a spoon, carefully scoop out the unmelted wax around the wick(s). Remove enough wax so that the unmelted portion is level with or lower than the melted section in the middle.
- Wipe the spoon with a paper towel to remove any excess wax. Properly dispose of the wax in a waste bin to avoid clogging drains.
- After scooping out the wax, light the candle again and let it burn until the pool of melted wax reaches the edge of the container. This step is crucial to resetting the candle's "memory" and ensuring an even burn.
- If desired, trim the wick to 1/4 inch before lighting the candle. This enables a cleaner and more consistent burn.
By following these steps, you can effectively remove the candle's "memory" and encourage a more even burn. However, it may take a few attempts to completely fix the issue. Remember always to exercise caution when handling lit candles and hot wax.

Burn for longer to melt the entire surface
Burning your candle for longer to melt the entire surface is a good way to prevent candle tunneling. This phenomenon occurs when only the wax surrounding the wick melts, leaving the outer rim of wax unmelted and solid. Tunneling can make it difficult to keep your candle lit and reduces its burn time. It also doesn't look very nice.
To prevent tunneling, it's important to ensure that your candle's first burn is long enough to melt the wax to the edge of the jar. This creates a "wax memory" or "candle memory", which will ensure that the candle burns evenly in the future. The longer first burn will prevent the wax from melting at different rates in subsequent burns. A good rule of thumb is to burn the candle for at least one hour per inch of container diameter.
If you notice that your candle has started to tunnel, you can try to melt the entire surface of the wax to "reset" its memory. This can be done by placing the candle in an oven for 5 minutes at 175 degrees Fahrenheit. Make sure that your candle jar is oven-safe. Alternatively, you can use a hairdryer on low speed to carefully melt the wax all the way to the edge of the container. Ensure that you hold the hairdryer far enough away from the candle to prevent splattering wax.
It is important to note that burning a candle for too long can be dangerous. Most candle manufacturers recommend stopping burning your candle when about 1/2 inch of wax remains at the bottom. Burning a candle all the way down can heat up the container to the point where it could crack or explode, and it could also lead to the wick burning.

Frequently asked questions
To see if your candle is burning evenly, make sure that the melt pool extends all the way to the edge of the jar. The flame should be calm and steady, and the unmelted layer of wax underneath should be smooth, level and flat.
Your candle may burn unevenly due to something called 'candle tunneling'. This is when only a small circle of wax melts around the wick while the candle is burning. This can be caused by a poorly made candle, where the wick is too small for the size of the candle, or if the first burn of a candle doesn’t last long enough.
There are a few methods to fix an unevenly melted candle:
- Using a hair dryer on low speed, melt the wax all the way to the edge of the container. This will reset the candle's memory so that it burns evenly in the future.
- Wrap a sheet of tin foil around the outside of the candle, leaving the center open for the flame. This will help to reflect heat back down to the candle's edge to aid in melting the wax.
- Scoop out the unmelted wax with a spoon until it is the same height or lower than the middle part that melts.
