Candle tunneling is a common issue that occurs when a candle burns down the middle, leaving a ring of hardened wax around the edges. This not only looks unsightly but also reduces the lifespan of your candle and diminishes its scent. This ring of wax is known as a 'memory ring', and it is established when a candle is extinguished before the wax has had a chance to fully melt outward from edge to edge. The good news is that there are several ways to remove this memory ring and restore your candle's even burn.
| Characteristics | Values |
|---|---|
| Reason for memory ring formation | Candle is extinguished before a full melt pool is achieved |
| How to prevent memory ring | Allow candle to burn for one hour for every inch of its width |
| Extinguish only after wax melts to the edge of the container | |
| Methods to remove memory ring | Use a blow dryer or hair dryer to melt the wax |
| Use aluminum/tin foil to reflect heat back to the candle's edge | |
| Scoop out the unmelted wax with a spoon | |
| Put the candle in the oven at 170-175 degrees Fahrenheit |

What You'll Learn
Using a hairdryer
A "memory ring" is created when a candle is not allowed to liquefy or melt from edge to edge during its first burn. This happens because previously melted wax is softer and takes less heat to melt again, so when you relight your candle, the wax melts at different rates, resulting in a tunneling effect. This wastes your candle and shortens its lifespan.
To fix this issue using a hairdryer, follow these steps:
- Ensure that your candle is extinguished.
- Use a hairdryer to gently heat the top layer of the candle. Set the hairdryer to low speed and high heat. Hold the hairdryer at a distance from the candle, being careful not to spatter any wax.
- Continue heating until the top layer of wax has completely melted and smoothed over. This may take several minutes, depending on the heat of your hairdryer.
- Relight your candle and let it burn for at least 30 minutes or until the tunneling is no longer visible.
- Set your candle aside and allow the wax to harden over the next few days. The time taken for the wax to reach full hardness will depend on the type of wax used.
This process resets the memory of the wax, widening the melt pool and helping to prevent future tunneling. It is important to be patient and cautious when using this method, as hot wax can be dangerous.

Wrapping in foil
Wrapping tin foil around a candle is a relatively easy method to fix candle tunneling. This method is also known as the foil method or the foil hack. It is important to note that the foil can get hot, so proceed with caution and let it cool before adjusting or removing it.
Firstly, light your candle. Then, carefully wrap a layer of foil around the top of the candle, making a domed lip with a hole in the top. This will allow the heat to stay concentrated within the candle and melt the rim of hard wax on the sides. Make sure the foil hangs over the built-up wax areas, but leave an opening in the centre so the wick can still burn properly. The opening in the centre of the foil should be large enough to allow plenty of oxygen in as it burns.
After about an hour or so, carefully remove the foil and you should have an even wax pool. You can also put your candle in the oven (preheated to about 170–175 degrees Fahrenheit) with foil wrapped around it for about 2 to 5 minutes to evenly melt the top.
The foil method works by reflecting heat back down to the candle's edge to aid in melting the wax. The memory ring can limit the burn radius of your candle, leading to tunneling. Candle tunneling occurs when a candle burns down its centre, leaving hard wax around the outside. This happens when the wick burns straight down the centre, instead of creating a melty pool of wax across the entire surface.

Preheating the oven
Preheating your oven is an effective way to fix candle tunnelling. This method works well for those with multiple candles exhibiting the same issue. Start by preheating your oven to a low temperature of around 170–175 °Fahrenheit (80 °Celsius). Place your candles on a baking tray. Optionally, you can cover the tops of the candles with aluminium foil to prevent direct heat exposure. Then, put the tray in the oven for about 5–10 minutes, keeping a close eye on the candles. Remove the candles from the oven and let them cool completely. Finally, trim the wick to the appropriate length before relighting.
It is important to note that you should not put a tunneled candle in the microwave, as most candles have metal wick tabs that could cause dangerous arcing inside the microwave.
The oven method is a hands-off approach that can help melt the wax surface and reset the memory ring. By preheating the oven to a suitable temperature, you can ensure that the heat is distributed evenly across the candle, allowing the wax to melt uniformly and reset the memory. This technique is particularly useful for melting the top layer of wax and preventing further tunnelling.
When using the oven method, it is crucial to monitor the candles closely to avoid any potential issues. Keep the candles in the oven for only a short duration, as prolonged exposure to high temperatures can cause the wax to melt excessively or even burn. Additionally, ensure that the candles are placed on a stable, flat surface within the oven to prevent any accidental spills or messes.
By following these steps and paying close attention to the process, you can effectively utilise the oven method to remove the memory ring from your candles and improve their burning performance.

Scooping out wax
Scooping out the wax is a simple and effective way to remove a candle's memory ring. This method is also known as the "spooning" technique. It involves using a spoon or similar tool to physically remove the unmelted wax around the edges of the candle. This method is best done when the candle is cold to avoid any potential burns.
The first step is to let your candle rest and cool down completely. This is an important safety precaution as it prevents any accidental burns. Once your candle is cold, take a spoon and carefully begin to scoop out the unmelted wax from around the edges. Be gentle and careful to avoid damaging the candle or its wick. Continue scooping until the wax around the edges is level with or lower than the wax in the middle.
After you have scooped out the excess wax, it is important to properly dispose of it. Wax can clog drains, so it is recommended to wipe the spoon clean with a paper towel and dispose of the wax in a waste bin.
Now that you have removed the memory ring, the next step is to relight your candle. This time, ensure that you let it burn long enough for the pool of melted wax to reach the edges of the container. This will reset the candle's memory and prevent tunneling.
Scooping out the wax is a straightforward and effective way to remove the memory ring from your candle. It is a physical method that directly removes the unmelted wax, allowing your candle to burn more evenly and reducing waste. Remember to always exercise caution when handling candles and hot wax to prevent any accidents.

Extending burn time
The memory ring of a candle is created when it is not allowed to liquefy or melt from edge to edge during its first burn. This creates a 'memory' for the candle, and it will continue to burn in the same pattern, wasting a lot of wax and reducing the candle's lifespan.
To extend the burn time of your candle and prevent the formation of a memory ring, it is important to ensure that the wax melts to the edge of the container during the first burn. The general rule of thumb is to allow your candle to burn for one hour per inch of its width. For example, a three-inch-wide candle should burn for at least three hours when first lit. This will allow the wax to melt evenly and prevent the formation of a memory ring.
If you notice that your candle has started to tunnel, there are a few tricks you can try to fix it and extend the burn time:
- The Foil Method: Wrap aluminium foil around the outside of the candle, creating a domed lip with a hole in the top. This will reflect heat back down to the candle's edge, aiding in melting the wax. Ensure the opening in the centre is large enough for adequate oxygen flow.
- The Hairdryer Method: Use a hairdryer to melt the wax around the edges of the candle. Place some newspaper around the candle to catch any splatters, and hold the hairdryer about six inches away from the candle. Set it to high heat and low speed.
- The Oven Method: Place your candle in the oven at 170-175 degrees Fahrenheit for a short period to melt the surface and reset the memory.
- Wax Scooping: Use a spoon to scoop out the unmelted wax around the edges. Ensure the candle is cold to avoid burns.
By addressing the memory ring issue, you can extend the burn time of your candle and enjoy its glow and fragrance for longer.
