Candles can be a great way to create a cozy ambiance, but they can also be frustrating when they don't burn evenly, a problem known as tunneling. This happens when only a small portion of the wax surrounding the wick melts, causing a vertical tunnel to form in the center of the candle. Tunneling can reduce the burn time of your candle and affect its scent and aesthetic appeal. Luckily, there are several ways to fix a tunneling candle and prevent it from happening again. This includes using external heat sources like hair dryers or heat guns to melt the hardened wax around the edges, creating an even surface, and using aluminum foil collars to capture the heat and melt the wax edges. Trimming wicks regularly and ensuring proper ventilation can also help prevent tunneling. With these tips, you can enjoy your candles to the fullest and create a warm and inviting atmosphere in your home.

How to fix a candle wick that's too short
If your candle wick is too short, there are several methods you can use to fix it. Firstly, you can light the wick and let it burn for 20 to 30 minutes. Check the flame height occasionally to see if the problem resolves itself. If the flame remains weak, blow out the candle and pour the melted wax onto a paper plate. Once it cools, dispose of the wax and plate. Alternatively, you can soak up the liquid wax with a paper towel or cotton swab after extinguishing the candle. The newly formed indent in the wax will expose more of the wick.
If the wick is completely covered in wax, you will need to replace it. Use a spoon or a butter knife to carefully scrape away the wax until the wick is exposed. You could also use a lighter or a hair dryer to melt the wax—remember to pour the excess wax into a separate heat-safe container. If you only need a little extra length, you can make a paper wick by tightly rolling up a scrap of thicker paper, like notebook or copy paper. Avoid using coloured paper or magazine pages, as the fumes from the ink can be toxic.
Another method is to melt the wax and expose the wick. You can do this by placing the candle in a double boiler or in an oven at 180 °F (82 °C) for about 15 minutes. Once the wax has melted, use a butter knife to scoop it out of the jar and place it in a bowl or pot. Thread the new wick through the metal bottom. You can also use this wax to dip the new wick in before placing it in the candle, which will help it burn more slowly and evenly.

How to fix candle tunneling
Candle tunneling is a common issue that occurs when a candle burns down its centre, leaving unmelted wax around the outside. This not only looks unsightly but also reduces the burn time and scent throw.
To fix minor candle tunneling, you can use a hair dryer or heat gun on high heat to melt the hardened wax around the edges of the container. This "resets the memory" of the wax, causing it to widen the melt pool towards the edges. Make sure to wear eye protection and clothes that can be washed in case hot wax splatters.
If your candle shows more severe signs of tunneling, you can try the foil trick. Cover the top of the candle with aluminium foil, leaving a small opening for the wick and flame. This increases the heat while keeping the vessel insulated, causing the excess wax to melt. Alternatively, you can gently scrape away the unburned wax around the edges with a butter knife or spoon to create an even surface. However, be gentle to avoid damaging the wick or container.
To prevent candle tunneling, ensure proper burning during the first use. Allow the candle to burn long enough, typically between one to four hours, for the entire top surface of wax to melt completely. Trim the wick to about 1/4 inch before each burn to promote an even and clean melt and to prevent debris from falling into the wax. Additionally, avoid placing the candle near open windows, fans, or drafty areas to prevent uneven burning caused by strong airflow.

How to fix an improperly burning candle
An uneven burn can occur due to several reasons, such as an incorrectly sized wick, poor candle wax composition, or drafty conditions. This phenomenon is known as tunnelling, where only the central wax portion melts, leaving the outer rim solid. This issue can be fixed, and there are several methods to achieve this.
Firstly, it is important to remember that the first burn is crucial in ensuring an even burn. Wax has a "memory" that influences its melting behaviour in subsequent burns. Thus, during the first burn, it is essential to allow the wax to melt from edge to edge. A good rule of thumb is to burn the candle for at least one hour per inch of container diameter.
If your candle is already showing signs of tunnelling, one method to fix it is to forcibly melt the entire surface of the wax to "reset" its memory. This can be done by using a hair dryer on medium to high heat to melt the top wax layer, ensuring an even surface. Refrain from overheating to prevent any damage, and make sure to keep a close eye on the candle while doing this. Once the wax has melted and smoothed, let it cool and solidify before lighting the candle again.
Another method is to use aluminium foil to reflect heat back down to the candle's edge and aid in melting the wax. Wrap the foil around the outside of the candle, leaving a window for the wick, and burn the candle for 1-2 hours. After removing the foil, you should have an even wax pool.
If there is a significant amount of excess wax around the edges, you can also try scooping it out with a spoon until it is level with the melted portion. This method ensures that the wick is not drowned.
To prevent tunnelling in the future, ensure your candle is placed on a level surface, away from drafts, and always trim the wick to about 1/4 inch before lighting.

How to fix a candle with a deep hole
If your candle has a deep hole, it may be suffering from candle tunneling or a sinkhole. This can be caused by the first lighting being too brief, an incorrectly sized wick, or the wax cooling too quickly.
To fix a sinkhole, you can use a heat gun or hairdryer to melt the wax around the sinkhole and fill it in. You can also use aluminium foil to reflect heat back down to the candle's edge to aid in melting the wax. If the sinkhole is very deep, you may need to melt down and remove the extra wax.
To prevent candle tunneling, it is important to let the entire surface of the candle melt before blowing it out, especially during the first burn. This usually takes at least an hour or two, depending on the size of the candle. You should also ensure that you are using the correct type of wick for your candle and that you are not overheating the wax.
If your candle has already started to tunnel, you can try to fix it by melting the entire candle surface with a hairdryer or heat gun. You can also use aluminium foil to reflect heat and aid in melting the wax. Additionally, you can try carving out the extra wax down to the bottom of the tunnel and then using the foil trick to prevent further tunneling.

How to fix a candle wick that's drowning in wax
A drowning candle wick is a common problem that occurs when the wick burns too quickly and becomes submerged in its own wax pool. This can happen due to various factors, such as the size of the wick being too small, low wick quality, or incorrect burning practices. Here are some detailed steps to fix a candle wick that is drowning in wax:
Soften the Wax
First, soften the wax around the wick by using a heat gun, blow dryer, or a long wand candle lighter. Hold the heat source over the candle wick to melt the surrounding wax. If using a blow dryer, set it to high heat and low speed. This process may take some time, so be patient.
Absorb Excess Wax
Use a paper towel, cotton pad, or spoon to gently absorb or scoop out the excess melted wax around the wick. This step will help expose the wick for easier access and prevent it from drowning further.
Adjust the Wick
Once the wick is exposed, use tweezers to gently straighten it if it is bent or leaning. Be careful not to break the wick. Then, trim the wick to the appropriate length, usually about 1/4 inch, to ensure an even burn.
Relight and Monitor
After adjusting the wick, relight your candle and allow it to burn for at least 30 minutes or until the wax on the surface has evenly melted. During this time, monitor the candle to ensure that the wick remains exposed and burning properly.
Prevent Future Issues
To prevent the wick from drowning again, it is crucial to address potential underlying issues. Ensure that you are burning the candle correctly, allowing the entire top layer of wax to melt during each burn. Additionally, maintain consistent burn durations, ideally about one hour for every inch of the candle's diameter.
By following these steps, you can effectively fix a candle wick that is drowning in wax and enjoy your candle's warm glow and fragrance once again.

Frequently asked questions
Candle tunneling occurs when only a small portion of the wax surrounding the wick melts, creating a small hole instead of an even melt across the surface. To fix this, you can melt the outer wax surrounding the tunnel to create an even surface. You can use a hairdryer, a heat gun, or even an oven to melt the wax. If there is excess wax, scoop it out with a spoon.
If your wick is too short, it may be because you forgot to trim it, causing it to curl and "mushroom" as it burns. To fix this, trim the wick to a length between ⅛ and ¼ of an inch. If the wick is buried, use tweezers or a Q-tip to nudge it back to an upright position.
To prevent tunneling, make sure you burn the candle long enough during its first few burns for the entire surface of the candle to melt. You can also use a candle topper, or illuma-lid, to stabilize the flame and distribute it uniformly across the surface of the candle.
A large pool of wax around the wick, also known as a "wax pool", can be caused by drastic temperature changes, especially during the winter. It can also be caused by a wick that is too small or low-quality, causing it to burn too quickly and drown in its own wax pool.
