Candle tunneling is a common issue that can be caused by a variety of factors, including the temperature in your home, the size of the wick, and the duration of the first burn. This issue can be frustrating as it can reduce the burn time of your candle and affect its scent and aesthetic appeal. However, there are several methods you can use to correct a tunneling candle and restore its appearance. This paragraph will provide an introduction to the topic of how to correct a tunneling candle, exploring the various techniques and best practices for addressing this issue.
How to Correct a Tunneling Candle
| Characteristics | Values |
|---|---|
| Reason for tunneling | Candle wasn't burned long enough during its first few burns |
| Candle memory | Previously melted wax takes less heat to re-melt, resulting in wax melting at different rates and causing a tunneling effect |
| Wick size | An undersized wick may not produce enough heat to melt the sides of the candle, causing the wax near the wick to melt faster than the surrounding walls |
| Temperature | Cold temperatures can cause some portions of the candle to melt at a slower rate, resulting in tunneling |
| Wax composition | Cheap candles with poor wax composition may not melt evenly |
| Drafts | Drafty conditions can cause uneven burning |
| First burn duration | Burning a candle for too long during its first use can cause overheating, potentially cracking the candle glass |
| Preventing tunneling | Burn candles for 1 hour per inch in diameter during the first use, or for 1-4 hours depending on the candle size |
| Methods to correct tunneling: | |
| Aluminum foil | Wrap foil around the top of the candle, leaving a small opening for the wick and flame. This increases the heat while keeping the vessel insulated, causing the excess wax to melt |
| Hair dryer | Use a hair dryer to melt the entire candle surface. Ensure the flame is extinguished before using the hair dryer, and hold it far enough away to avoid spattering wax |
| Oven | Place the candle in an oven heated to 175 °F (79 °C) for 5 minutes to help melt the wax. Remove the candle with oven mitts and let the wax harden before lighting it again |
| Spoon/butter knife | Use a spoon or butter knife to gently scrape away or scoop out the unburned wax around the edges, making the candle flat. Be gentle to avoid damaging the wick or container |
| Wick adjustment | Expose about 1/4 inch of unburnt wick by trimming the wax around it. Ensure the wick is the appropriate length for a proper burn |

What You'll Learn
Use a hairdryer to melt the wax evenly
Candle tunneling is a common issue that occurs when a candle burns down its centre, leaving a ring of hardened wax around the outside. This not only looks unsightly but also reduces the candle's burn time and affects its scent.
To correct a tunneling candle with a hairdryer, follow these steps:
- Set your hairdryer to its hottest setting.
- Hold the hairdryer directly over the top of the candle, ensuring that the airflow is evenly distributed across the surface.
- Turn on the hairdryer and blast the wax until the top layer softens and settles into a flat surface. It may take a few minutes for the wax to melt evenly, so be patient and maintain a steady hand.
- Once the wax has melted and smoothed, turn off the hairdryer and allow the wax to cool and solidify.
- After the wax has hardened, trim the candle wick to about 1/4 inch to promote an even and clean burn the next time you light the candle.
Using a hairdryer is an effective way to fix minor tunneling issues. However, for more severe cases of tunneling, you may need to try alternative methods, such as using foil to increase the heat and insulation, or gently scraping away the excess wax with a butter knife or spoon.

Wrap the candle in aluminium foil
Wrapping a candle in aluminium foil is a simple hack to reverse tunnelling and preserve the life of the candle. Tunnelling occurs when the wax burns unevenly, creating a tunnel in the centre as the wax burns down instead of out. This happens when the wax isn't burned long enough to reach the vessel's edges, causing the candle to only burn as wide as the wax in the centre.
To fix a tunnelling candle with aluminium foil, start by lighting the candle. Then, take a sheet of aluminium foil and wrap it around the edges of the candle jar, creating a tent-like structure. Ensure that the foil covers the entire opening of the vessel, with a hole in the middle for the wick. The hole should be big enough to keep the wick lit, but not so big that all the heat escapes. This creates a foil house to trap heat, melting the wax that is higher than the rest of the candle.
Let the candle burn for about an hour or until all the built-up wax on the edge of the vessel melts. Keep an eye on the candle while it burns, as the foil can sometimes extinguish the flame. Once the wax has liquified, carefully remove the foil and continue burning the candle, or gently put it out to enjoy later.
The foil method is a temporary fix to melt the wax and should be removed once the desired result is achieved. It is important to note that this method may not work for severely tunnelled candles, and other methods such as using a heat gun or a candle topper may be more effective. Additionally, maintaining proper burning habits, such as trimming wicks and ensuring adequate burn time, can help prevent tunnelling in the first place.

Put the candle in the oven
If your candle has started to tunnel, you can put it in the oven to fix it. Candle tunneling occurs when only the centre of the candle, around the wick, is melted and burnt down, making it harder to light the candle each time.
To correct this issue by putting the candle in the oven, follow these steps:
- Warm up your oven to 175 °F (79 °C).
- Place the candle in the middle of a cookie sheet and put it inside your oven.
- Leave the candle in the oven for 5 minutes.
- Remove the candle from the oven using oven mitts to protect your hands.
- Let the wax harden before lighting your candle again.
If you still notice tunneling, return the candle to the oven and check it again after 1-2 minutes. You can also try pushing the wax around the edges towards the wick to help correct the issue.
Putting your candle in the oven is a quick and easy way to fix candle tunneling and prevent it from getting worse. Remember to always handle candles with care and take the necessary precautions to avoid burns.

Scrape out excess wax
Tunneling is a common issue with candles, and it can be frustrating when it happens. The good news is that there are several ways to fix it, and one of them is by scraping out the excess wax.
Firstly, it is important to understand why tunneling happens. When a candle is not burned long enough during its initial burns, it creates a "'memory'" where the top layer of wax does not melt to the edge. This results in a tunnel forming around the wick, with unburned excess wax lining the walls. This tunnel deepens every time the candle is lit, and it can eventually make the wick inaccessible for relighting.
To correct this issue, you can gently scrape away the unburned wax around the edges with a butter knife or spoon. Be careful not to damage the wick or the container while doing this. The goal is to create a flat surface, allowing the wax to melt evenly the next time you light the candle. Make sure to stop scraping when the wax is level with the middle part that melts.
Once you have scraped away the excess wax, you can relight your candle. This time, ensure that it burns long enough for the melted wax to reach the edges of the container. This will help reset the candle's "memory" and prevent tunneling from occurring again.
While scraping out the excess wax is an effective method, it may result in some wax being wasted. Additionally, it is important to be cautious when handling the candle and hot wax to avoid any accidents. Always make sure to follow basic candle safety guidelines, such as never leaving a burning candle unattended and keeping flammable objects away from the flame.

Trim the wick
Trimming the wick of a candle is an important step in preventing and fixing candle tunneling. When a candle is burned for the first time, it is crucial to ensure that it burns long enough for the wax to melt to the edge of the container. This initial burn creates a "'memory'" for the candle, and subsequent burns will follow this pattern. If the candle is not allowed to melt evenly across the surface during the first burn, tunneling can occur.
To prevent tunneling, it is recommended to trim the wick to about 1/4 inch before each lighting. This promotes a cleaner and more consistent burn. By trimming the wick, you can prevent debris from falling into the melted wax and avoid the formation of a "mushroom" shape on the wick, which can create smoke and soot. A candle wick trimmer or scissors can be used for this purpose, ensuring that the wick is not cut too short.
The size of the wick also plays a significant role in candle tunneling. An undersized wick may not produce enough heat to melt the wax evenly, resulting in tunneling. Therefore, it is important to ensure that the wick is of adequate length and thickness for the size of the candle. If the wick becomes too short or is buried in wax, it may need to be replaced with a new wick of appropriate size.
Trimming the wick is an essential aspect of candle care and maintenance. By regularly trimming the wick and ensuring proper burning during the first use, candle tunneling can be prevented or minimized. This will allow you to enjoy your candle evenly and efficiently, maximizing its burn time and aesthetic appeal.
