How To Fix A Candle That Tunnels

what to do if a candle tunnels

Candle tunneling is a common issue that occurs when a hole forms down the center, leaving unused wax at the edges. This not only wastes your candle but also shortens its lifespan and affects its scent. Luckily, there are several simple fixes to this problem. Firstly, it is important to prevent any further tunneling by blowing out the candle as soon as you notice the formation of tunnels. Then, you can try to melt the outer wax surrounding the tunnel to create an even surface. This can be done with a hairdryer, heat gun, or by wrapping aluminum foil around the candle to reflect heat back down to the candle's edge.

Ensure the candle is burnt long enough

Candle tunnelling is a common issue that occurs when a candle burns down the middle, leaving a thick ring of unmelted wax around the edges. This not only wastes your candle but also shortens its lifespan.

To prevent tunnelling, it is important to ensure that the candle is burnt long enough, especially during its first burn. This is because wax has a "memory". When a candle is lit for a short time, it does not allow the melted pool of wax to reach the edge, creating a barrier that remains during subsequent lightings. Therefore, during the first burn, it is important to burn the candle long enough for the entire top layer of wax to melt from edge to edge. This usually takes at least an hour or two, depending on the size of the candle.

If you are unable to dedicate that amount of time, it is best to avoid lighting the candle. This may seem counterintuitive, but it will help extend the life of your candle.

Additionally, it is important to keep in mind that the optimal amount of fragrance is released when the entire top of the candle becomes completely liquified. Therefore, burning the candle long enough will also ensure that you are getting the most out of its scent.

Trim the wick

Trimming the wick is an important step in preventing and fixing candle tunnelling. It is recommended to trim the wick to 1/4 inch before each lighting for a cleaner and more consistent burn. This ensures that the candle burns evenly and prevents the formation of a deep well or "tunnel" in the centre.

To trim the wick, use a wick trimmer or scissors to cut the wick to the desired length. If the wick is too short, it may be difficult for it to melt the wax evenly, leading to tunnelling. In this case, you may need to expose more of the wick by gently digging around it or replacing it with a new wick of the appropriate size.

It is also important to keep the wick centred and to remove any debris inside the tunnel. This will help the candle burn more evenly and prevent tunnelling.

Trimming the wick is just one aspect of candle care. It is also important to ensure that the candle is burned long enough during its first burn to create a memory layer. This means allowing the entire top layer of wax to liquify before snuffing out the flame.

Additionally, it is recommended to store candles in a cool and dry place to prevent the wax from softening, which can also contribute to tunnelling.

Use a hairdryer to melt the wax

Candle tunnelling is a common issue, but it can be fixed with a few simple tricks. Tunnelling occurs when only the centre of the wax melts, leaving a thick ring of unmelted wax around the edges. This wastes your candle and shortens its lifespan.

One way to fix candle tunnelling is to use a hairdryer to melt the wax. Here's how to do it:

  • For safety, wear eye protection and clothes that can be washed if wax gets on them. Lay some old newspaper beneath the candle to protect your table or floor.
  • Trim the wick to about 1/4 inch to promote an even and clean burn.
  • Extinguish the flame if it is lit.
  • Turn on your hairdryer and gently warm the top layer of the candle until the wax melts evenly. Hold the hairdryer far away and slowly move it closer to an appropriate distance where it won't be blowing melted wax everywhere. Use a low setting and avoid overheating to prevent any damage.
  • Continue heating until the entire top surface of the wax has completely melted and smoothed over.
  • Relight your candle and enjoy its renewed glow.

Using a hairdryer works best if the tunnelling has just begun and is only a few centimetres deep. If the sinkhole is deeper, you may need to spend more time melting down and removing the extra wax, or try a different method such as the aluminium foil method.

Wrap the candle in tin foil

Wrapping a candle in tin foil is a common method used to fix candle tunnelling, also known as uneven wax melt. This occurs when a hole forms down the centre of the candle, leaving unused wax at the edges.

To fix this, you can use tin foil to reflect heat back down to the candle's edge to aid in melting the wax. First, ensure that the candle is completely cooled before attempting any fixes. Then, cut a piece of tin foil large enough to wrap around the top of the candle, leaving some space in the centre for the wick to breathe. Form a dome shape with the foil, covering the top and extending it down the sides. Make sure the foil is secure but not too tight, allowing some space for heat circulation.

Once the candle is wrapped, light it and let it burn for 1-2 hours. The foil will trap the heat and allow the outer wax to soften and melt, creating an even burn. Keep an eye on the candle to ensure the foil stays in place and there is no excessive heat buildup.

This method may take a few tries and the foil will get hot, so be careful when adjusting or removing it. You can also try other methods such as using a hair dryer or heat gun to melt the hardened wax around the edges of the container.

Use a candle warmer

If you're tired of dealing with candle tunnelling, a candle warmer is an excellent solution. Candle warmers are electric devices that gently heat the wax from below, ensuring an even melt without the need for a flame. This not only solves the issue of tunnelling but also helps you get the most out of your candle by fully melting the wax, including those last bits at the bottom of the jar.

When using a candle warmer, it's important to follow some best practices for optimal results. Firstly, make sure your candle is placed securely on the warmer, ensuring good contact between the wax and the heating surface. Allow sufficient time for the warmer to melt the wax evenly, especially if you're dealing with a large candle or one with a significant amount of wax.

While candle warmers provide a consistent heat source, you can also combine this method with other techniques to speed up the process and ensure an even melt. Before placing your candle on the warmer, trim the wick to about a quarter of an inch. This promotes a cleaner and more consistent burn. Additionally, consider using aluminium foil to create a dome-like structure over the candle, with an opening at the top for airflow. The foil reflects heat back down to the candle's edge, aiding in melting the outer wax. Just be cautious when handling the foil, as it can get hot.

If you're concerned about the aesthetics of using a candle warmer, rest assured that there are various stylish options available. Candle warmers come in different designs, from simple and sleek to more decorative styles that complement your candle and enhance the overall ambiance. Whether you prefer a modern or rustic look, you can find candle warmers that suit your taste and home décor.

By using a candle warmer, either on its own or in combination with other techniques, you can effectively address candle tunnelling. With consistent heat and proper care, your candle will melt evenly, releasing its fragrance and creating the cosy atmosphere you desire.
