Candle tunneling is one of the most common issues candle lovers face. It happens when a candle burns straight down the middle, leaving unused wax around the edges, which shortens its lifespan and reduces scent throw. Fortunately, there are easy ways to fix and prevent tunneling, ensuring you get the most out of your candle.
What Causes Candle Tunneling?
Candle tunneling typically happens due to:
- Short burn times – Not allowing the wax to melt evenly across the surface.
- Improper wick size – A wick that is too small may not generate enough heat.
- Drafty conditions – Air movement can cause uneven burning.
How to Fix Candle Tunneling
1. The Aluminum Foil Method
One of the most effective ways to fix tunneling is using aluminum foil:
- Wrap a strip of foil around the rim of the candle, creating a slight dome.
- Leave an opening at the top to allow the flame to breathe.
- Burn the candle for 1-2 hours until the wax melts evenly across the surface.
- Remove the foil and let the candle cool.
2. The Hair Dryer or Heat Gun Trick
If tunneling is minor, use a hair dryer or heat gun to melt the excess wax around the edges:
- Set the dryer or heat gun to low heat.
- Hold it a few inches above the candle and slowly melt the top layer of wax until it’s even.
- Allow the wax to cool and reset before relighting.
3. Warming Plate or Candle Warmer
If the wick has become too short to fix, place the candle on a candle warmer or warming plate. This method gently melts the wax evenly without relighting the wick, allowing you to use the remaining wax.
How to Prevent Candle Tunneling
1. Allow a Full Melt Pool on the First Burn
The first time you burn a candle, allow it to melt completely across the surface before extinguishing it. This usually takes 1-3 hours, depending on the candle size.
2. Trim the Wick Properly
A wick that is too long can create a large, flickering flame, causing uneven burning. Trim the wick to ¼ inch before each burn.
3. Avoid Drafts
Burn candles away from fans, vents, and open windows to prevent uneven melting.
4. Choose the Right Candle Size for Your Space
Large candles need a longer burn time, while smaller candles are better suited for short burns. Consider a candle that fits your typical burning duration to avoid premature extinguishing.
Final Thoughts
Candle tunneling can waste wax and shorten burn time, but with these easy fixes and prevention tips, you can ensure an even burn and get the most out of your candles. Proper care and burning techniques will help you extend your candle’s lifespan and enjoy its full fragrance potential.
