How to Fix a Candle That Is Tunneling
Candle Tunneling: What It Is & How to Prevent It
Have you ever looked at your candle and noticed that the wax is melting down the center while a thick ring of un-melted wax remains around the edges?
That's called candle tunneling.
Not only can it make your candle look uneven, but it can also prevent you from getting the full experience from the wax and fragrance you've purchased.
The good news is that understanding why tunneling happens can help you prevent it.
What Is Candle Tunneling?
Candle tunneling occurs when the wax directly around the wick melts while the wax farther toward the edges remains solid.
Instead of developing a more even melt pattern across the surface, the candle creates a tunnel down the middle.
What Causes Candle Tunneling?
One of the most common causes is repeatedly burning a candle for very short periods.
For example, if you light your candle for 10 or 15 minutes and extinguish it before the wax has had enough time to melt across the surface, the candle can begin developing a memory of that smaller melt area.
Over repeated burns, that can contribute to tunneling.
How Can You Prevent Candle Tunneling?
1. Give Your Candle Enough Time
Don't light your candle for only a few minutes every time.
Instead, allow enough time for the wax to melt reasonably evenly across the surface while staying within the manufacturer's recommended burn time.
2. Keep Your Wick Properly Trimmed
A wick that becomes too long can create a larger flame and contribute to an inconsistent burn.
Trim the cooled wick to approximately ¼ inch before each burn, unless your candle's care instructions specify otherwise.
3. Keep the Candle Away From Drafts
A fan, vent or open window can cause the flame to burn unevenly.
Choose a stable location away from direct airflow.
4. Don't Move the Candle While Hot
Moving a candle while the wax is liquid can disturb the melt pool and create unnecessary messes.
Let the candle cool before moving it.
Can a Tunneling Candle Be Fixed?
Sometimes an unevenly burning candle can improve with proper subsequent burns, depending on how severe the tunneling is and the candle's design.
However, you should always prioritize the manufacturer's burn and safety instructions.
Don't use unsafe methods to force wax to melt, and don't continue burning a candle simply to eliminate a ring of wax.
The Best Way to Prevent Tunneling
The easiest solution is to develop good candle habits from the very first burn.
Think of candle care as part of the experience.
Trim the wick.
Choose the right location.
Give the candle enough time to burn properly.
And always follow the instructions provided with your candle.
Final Thoughts
Candle tunneling is frustrating, but it's also something you can often help prevent with consistent candle care.
If you're investing in a beautiful fragrance, take a few extra minutes to care for it properly.
Your candle—and your home fragrance experience—will thank you.
