How to Fix Candle Tunneling: Simple Tips for a Perfect Burn

If you’ve ever lit a candle and noticed that it’s burning down the center while leaving wax along the sides, you’ve experienced candle tunneling. While it’s common, it can be frustrating—and wasteful. Luckily, fixing candle tunneling is easier than you might think!

What Causes Candle Tunneling?

Candle tunneling happens when the wick burns down the center of the wax faster than the outer edges. Common causes include:

• Wick too small for the candle size

• Burning the candle too briefly during the first use

  Step 1: Use the Foil Trick

  One of the easiest ways to fix a tunneled candle is with aluminum foil:

  1. Cut a piece of foil and wrap it around the top of the candle, leaving a small opening over the wick.

  2. Light the candle. The foil traps heat and melts the wax along the edges.

  3. Once the wax reaches the sides, remove the foil and let the candle burn as usual.

  Tip: Keep an eye on the candle to prevent overheating or excessive smoke.

  Step 2: Create a “Wax Bridge”

  Another method is to redistribute the wax manually:

  1. Use a butter knife or spoon to scoop some of the unmelted wax from the edges.

  2. Carefully drip it into the tunnel.

  3. Light the candle—now the wick will have wax along the sides to burn evenly.

  Step 3: Reset the Wick

  Sometimes, tunneling is caused by a misaligned or too-short wick. Try this:

  • Use a toothpick or skewer to nudge the wick so it’s centered.

  • Trim the wick to ¼ inch before lighting to ensure a clean, steady flame.

  Step 4: Prevention Tips for Future Burns

  • First burn matters: Always let the candle burn long enough for the wax to melt across the entire surface during the first burn.

  • Trim the wick: Keep it at ¼ inch before every burn to avoid uneven melting.

  • Avoid drafts: Wind or fan airflow can cause one side of the candle to burn faster.

  • Choose the right candle size: Make sure the wick and container are proportionate.

  Candle tunneling doesn’t have to be a candle killer! With these simple tips, you can enjoy even burns, longer-lasting candles, and beautifully melted wax every time.

  ✨ Pro Tip: If all else fails, turning a tunneled candle into a new creation—like a wax melt or layered candle—can give it a second life!
