Candle tunneling is a common problem, where a candle burns down the middle, leaving unburnt wax around the edges. This happens when a candle isn't burnt long enough during its first few uses, or if the wick is too small or off-centre. Candle tunneling can ruin a perfectly good candle, affecting its aesthetic appeal, burn time, and scent throw. However, there are several ways to fix this issue and prevent it from happening again.
Characteristics and Values
| Characteristics | Values |
|---|---|
| Preventing tunneling | Burn the candle for 1 hour per inch in diameter during the first use. |
| Trim wicks to 1/4 inch before each burn. | |
| Avoid placing candles near open windows, fans, or drafty areas. | |
| Use a candle topper. | |
| Using aluminum foil | Wrap the candle with aluminum foil, leaving a small opening for the wick and flame. |
| Craft a foil collar for the candle, leaving a window for the wick. | |
| Using a hair dryer | Use a hair dryer on medium to melt the top layer of wax. |
| Use a hair dryer to remove wax around the wick. | |
| Using a heat gun | Use a heat gun to melt the surface of the wax. |
| Use a heat gun to remove wax around the wick. | |
| Using an oven | Place the candle in an oven at 200°F or 93°C for 20 minutes. |
| Using a spoon or butter knife | Gently scrape away unburned wax around the edges. |
| Replacing the wick | Remove wax around the wick with a spoon. |
| Replace the wick if it is too short. |

Using aluminium foil
Candle tunneling is a common issue that occurs when a candle burns unevenly, leaving unused wax along the sides. This can be caused by various factors, such as an initial burn that was too short, a wick that is too small, or ingredients clogging the wick. Luckily, there is a simple and effective solution to this problem—the aluminium foil trick.
The aluminium foil trick involves wrapping a strip of aluminium foil around the top portion of the candle, creating a snug "hat". The foil should cover the entire opening of the vessel, with a small opening in the centre for the wick to peek through. By doing this, you are creating a heat barrier that traps the heat and reflects it back into the wax, melting the wax uniformly and preventing tunneling. This method is temporary and should only be used for 15 to 20 minutes or until the wax pool reaches the edge of the candle.
To further enhance the effectiveness of the aluminium foil trick, you can combine it with other techniques. Before lighting the candle, ensure the wick is trimmed to about 1/4 inch or 5-6mm. This helps create a smaller, more even flame that will melt the wax more efficiently. Additionally, during the initial burn, let the candle burn for an extended period, ideally one hour per inch of its diameter or a minimum of 2-3 hours, to allow the entire top layer of wax to melt evenly.
By incorporating the aluminium foil hack and following proper wick care and burning practices, you can effectively prevent and fix candle tunneling. Your candles will burn longer, more evenly, and beautifully, maximising their value and enjoyment.

Trimming the wick
To trim the wick effectively, it is recommended to trim wicks to a length of about 1/4 inch before each burn. This ensures that the wick is not too short, which can cause debris to fall into the wax or make the wick "mushroom", leading to smoke and soot. A wick that is too long can also cause the wick to become buried in wax, so it is important to find the right balance.
If your wick is already buried in wax, you can carefully dig around it to expose about 1/4 inch of unburnt wick. This method can be used to immediately solve tunneling issues, but it may result in some wax and burn time being lost.
For candles with multiple wicks, ensuring that all wicks are trimmed evenly will promote even melting and prevent tunneling. Regularly trimming your wicks will also help to prevent tunneling and maximise the lifespan of your candles.

Using a hair dryer
Firstly, ensure the candle flame is extinguished. Next, grab your hair dryer and turn it on, adjusting the settings to low speed and high heat. Hold the hair dryer around six inches away from the candle, directing the heat towards the unmelted edges. Move the hair dryer slowly towards the candle until you reach an appropriate distance—this will prevent hot wax from blowing everywhere. Continue applying heat until the wax softens and becomes smooth. This process may take a while, so patience is key!
For safety, it is recommended that you wear protective eyewear and clothing that can be easily washed in case any wax spatters. Additionally, ensure you place some newspaper around the candle to catch any wax splatters.
Once the wax has melted evenly, relight your candle and let it burn for at least 30 minutes, or until the tunneling is no longer visible. Finally, set the candle aside and allow the wax to harden over a few days.

Scraping away wax with a knife or spoon
Candle tunneling is a common issue that occurs when a candle burns down the middle but leaves unmelted wax around the edges. This usually happens when the candle isn't burned long enough during its first use, or if the wick is too small or off-centre.
One way to fix this issue is by gently scraping away the wax with a knife or spoon. Here's how to do it:
Firstly, assess the depth of the tunneling. If it is severe (around 1-2 inches deep), it may be difficult to salvage. However, if the sinkhole is shallow (around 1/2 inch or less), you can fix the tunneling without too much trouble.
Next, take a butter knife or spoon and gently scrape away the unburned wax around the edges, flattening the candle's surface. Be careful not to damage the wick or the container. If the wick is too short, dig around to expose it and give it some air. Ensure it is the appropriate length for a proper burn.
If your wick is still buried in wax after scraping, you may need to remove some of the wax with a spoon. You can also try using a hair dryer on medium heat to melt the wax around the wick, exposing about a 1/4-inch length of unburnt wick.
Once you have exposed the wick, relight your candle and allow it to burn for at least 30 minutes or until the tunneling is no longer visible. Set the candle aside and let the wax harden for a few days before burning it again.
This method of scraping away wax with a knife or spoon is a simple and effective way to fix candle tunneling and restore an even burn to your candle.

Using a candle warmer
Candle tunneling is a common issue that occurs when a candle burns down its centre, leaving unmelted wax around the outside. This problem can be addressed by using a candle warmer, an electric device that melts candles without an open flame. Candle warmers produce a consistent and uniform heat that melts the wax evenly from the bottom up, preventing tunneling and maximising burn time.
Candle warmers are an effective way to fix candle tunneling because they melt the wax uniformly, removing the "memory" of the wax. The "memory" refers to the fact that previously melted wax takes less heat to re-melt, causing the wax to melt at different rates and resulting in a tunneling effect. By using a candle warmer to melt the wax evenly, you can reset the "memory" and prevent tunneling from occurring.
To use a candle warmer to fix candle tunneling, start by extinguishing the flame if it is lit. Then, place the candle on the warmer and turn it on. Allow the candle warmer to heat the wax evenly, removing the "memory" and creating a uniform surface. Once the wax has reached a uniform consistency, you can relight the candle and enjoy an even burn.
It is important to note that candle warmers may not be effective for severe tunneling. If the sinkhole is deeper than half an inch, it may be difficult to salvage the candle. In such cases, other methods, such as using a hair dryer or aluminium foil, may be more effective in fixing the issue.
Additionally, candle warmers are an excellent way to prevent candle tunneling. By using a candle warmer, you can ensure that the wax melts evenly from the beginning, preventing the formation of a tunnel. This not only maximises the burn time of the candle but also enhances the scent throw, making the aroma more pronounced.
