Candles are a great way to create a cosy atmosphere, but they can be frustrating when they won't stay lit. There are several reasons why this might happen, such as an overly long wick, debris in the wax, or the candle tunneling - when a candle burns straight down the centre without creating a full melt pool. If your candle won't stay lit, there are a few troubleshooting methods you can try, such as trimming the wick, removing debris, or melting and draining excess wax.
| Characteristics | Values |
|---|---|

| Excessively short wick | The wick may drown in the wax, fail to catch a flame, or burn with a very low flame |
| Tunneling | A tunnel forms around the wick, making it difficult for the wax around the edges to melt |
| Wick debris | Obstructs the wick and causes the candle to extinguish |
| Excess wax | May extinguish the flame |

What You'll Learn

The candle wick may be too short
If your candle wick is too short, it may be difficult to light and stay lit. This is because the wax is what fuels the candle's flame, and the flame draws the wax upwards through the wick. If the wick is too short, there may not be enough wax being drawn up to fuel the flame.
A short wick may also cause the candle to drown in the wax, as the wick is burning down faster than the wax is being drawn up. This can cause the flame to go out. Additionally, a short wick may not be able to provide enough fuel for the flame, causing it to burn with a very low flame that may easily extinguish.
To remedy this issue, you can try to give the wick more space from the wax. Melt the wax around the wick with a lighter or matches, then dab or drain the excess wax with a paper towel. You can also try scraping out the tunnelled wax with a knife until the wax is level with the surface of the wick. This will give the wick more room to breathe and draw up the wax.
It is important to note that the ideal wick length may vary depending on the type of candle and wax. For example, some sources suggest keeping the wick about 1/4" or 6mm above the surface of the wax, while others recommend keeping it at about 1/8". It may take some experimentation to find the optimal wick length for your candle.

The candle wick may be too long
If your candle won't stay lit, it could be because the candle wick is too long. An excessively long wick is one of the most common reasons candles blow out. Before lighting your candle, trim the wick to about 1/4 of an inch long. Aim to keep your wicks about 1/4" or 6mm above the surface of the wax. A long wick can create a large, flickering flame that may snuff itself out. The wax fuels the candle's flame, and the flame draws the wax upwards through the wick. Therefore, if the wick is too long, the wax may not be able to reach the flame.
If you are using a wooden wick, it is important to note that the wick needs to be short to pull the wax up. However, it also can't be too short, or it may drown in the wax, fail to catch a flame, or burn with a very low flame. Try to keep it at about 1/8" long, and shorten it as needed.
If you are still having issues with your candle staying lit, try letting it burn for 2-4 hours to allow the wax to melt all the way to the edge of the container. If you do not do this, a tunnel may start to form around the wick, making it more difficult for the wax around the edges of the jar to melt. Eventually, the tunnel can become too deep for fresh oxygen to flow in, and your candle will have trouble staying lit.

The candle wick may be dirty
If your candle won't stay lit, it could be because the wick is dirty. The wax is what fuels the candle's flame, not the wick. The flame draws the wax upwards through the wick, so if the wick is dirty, the wax may not be able to reach the flame.
When there is too much debris floating in the wax, the flame may struggle to stay lit. To prevent this, always trim your wick before lighting the candle. You can do this by breaking off the top black bits of the wick with your fingers, or by using nail clippers, scissors, or a wick trimmer. After trimming, turn the wick upside down to remove any chopped bits of burnt wick.
In addition to trimming the wick, you should also ensure that there is no debris in the wax that could obstruct the wick. Matches, wick trimmings, or other debris may fall into the wax and cause the candle to extinguish. If this happens, gently remove the debris with a metal butter knife, wick dipper, or tweezers.
If your candle still won't stay lit after trimming the wick and removing debris, you may need to take additional steps to address the issue. Try using a paper towel or napkin to soak up excess wax, allowing more room for the wick to breathe. If this doesn't work, you can scrape out the top wax with a spoon until the wick is tall enough to stay lit.
By keeping the wick clean and free of debris, you can help ensure that your candle stays lit and burns properly.

The candle may be 'drowning' in wax
If your candle won't stay lit, it may be because the wick is drowning in wax. This can happen when the wick is too short, preventing the wax from reaching the flame. The ideal wick length is between 1/8" and 1/4" above the surface of the wax.
To fix this issue, first, blow out the candle. Then, use a paper towel to soak up the excess wax around the wick, creating more space for the wick to breathe. Alternatively, you can use a spoon or knife to scrape out the excess wax. If there is debris in the wax, use a metal butter knife, wick dipper, or tweezers to gently remove it.
To prevent this issue in the future, ensure that you allow enough time for the wax to melt all the way to the edges of the container during the first burn. This helps to prevent tunneling, which can make it difficult for the wick to access the wax. Additionally, regularly trim your wicks to the appropriate length and remove any debris that may have fallen into the wax.

The candle may have debris in it
If your candle won't stay lit, it may be because there is debris in it. This is a common issue with candles, and it can be easily fixed. Debris in the candle can obstruct the wick, causing the candle to extinguish. The debris could be in the form of matches or wick trimmings that have fallen into the candle.
To resolve this issue, you can gently remove any debris using a metal butter knife, a wick dipper, or a pair of tweezers. It is important to ensure that you remove all the debris so that the wick is clear and can function properly.
Additionally, you may need to address the issue of "tunneling". Tunneling occurs when a candle is not burned long enough, causing a depression or tunnel to form around the wick. This makes it difficult for the wax around the edges to melt, resulting in the wick drowning in the wax. To prevent tunneling, ensure that you burn your candle long enough for the wax to melt all the way to the edges of the container, usually around 2 to 4 hours.
If tunneling has already occurred, you can try to fix it by using a paper towel or napkin to soak up excess wax, allowing more room for the wick to breathe. You can also try scraping out the excess wax with a knife or spoon until the wick is tall enough to stay lit.
By removing debris and addressing tunneling, you can help ensure that your candle stays lit and burns evenly.

Frequently asked questions
There could be several reasons for this. Firstly, check the length of the wick—if it's too long, trim it down to about 1/4 inch. If the wick is too short, try melting the wax around it and then use a paper towel to remove the excess wax.
To prevent tunneling, ensure that during the first burn, you allow the wax to melt all the way to the edges of the container. This helps to prevent tunneling and ensures an even burn in subsequent uses.
Candle tunneling occurs when a tunnel forms in the wax, making it difficult for the wax around the wick to fully melt. This can happen when a candle is extinguished too soon, resulting in uneven wax levels.
To fix a tunneling candle, use a knife to scrape out the tunneled wax until the wax is level with the surface of the wick. Then, let the candle burn for 3-4 hours to allow the wax to melt and "reset" the memory of the candle.
