Candle Tunneling Fixes
Tunneling is when your candle burns a hole straight down the middle and leaves a wall of wax around the sides. Good news: it's fixable, and easy to prevent next time.
First things first
Why does tunneling happen?
A short first burn
The wax didn't melt all the way to the edges, so a full melt pool never formed. Candles have a "memory," and it keeps burning down that same path.
Drafts or fans
Moving air pushes the flame and its heat to one side, so the wax melts unevenly.
A wick that's off
Too long or too short, either one can throw off an even burn.
Do this on the first burn
How to prevent it
Go long on the first burn.
Keep it lit until the melted wax reaches the edges of the jar, usually 2–3 hours. This one habit does most of the work.
Trim to ¼″

Skip the breeze
Keep it away from open windows, vents, and fans.
Go flat
A level, heat-safe surface helps the melt pool form evenly.

Quick reset
1. The foil hug
- Trim the wick to ¼″ and light it.
- Wrap a loose foil collar around the top of the jar, leaving an opening in the center.
- Let it burn 30–60 minutes. The foil bounces heat onto the wax walls so they melt down.
Stay with it the whole time, and let the foil cool before you remove it. It gets hot.
Slow & steady
2. The guided burn
- Relight with the wick trimmed to ¼″.
- Let it burn until the melted wax reaches the edges (up to 4 hours).
- Repeat over a few sessions until the surface evens out.
Stubborn cases
3. Level the surface
- Wait until the candle is completely cool.
- Use a clean spoon or butter knife to remove the extra wax ringing the rim.
- Follow up with a guided burn to reset the melt pool.
Level up
Pro tips
- Skip quick burns. Sessions under about an hour are how most tunneling starts.
- Got a draft you can't avoid? Rotate the candle 90° between sessions.
- Seeing soot on the glass? Trim the wick and check for drafts.
