How to Fix a Tunneling Candle: Simple Solutions for a Better Burn

There’s nothing more frustrating than lighting a beautiful candle, only to watch it burn straight down the middle, leaving wasted wax along the sides. This is called tunneling—and it happens to the best of us. But don’t worry. With a few simple steps, you can fix a tunneling candle and prevent it from happening again.

At Mitala Candle Co., we want you to enjoy every moment (and every ounce) of your candle. Let’s walk through how to fix it.

What Is Candle Tunneling?

Candle tunneling happens when the wax around the wick doesn't melt all the way to the edges of the jar. This creates a “tunnel” through the center, wasting wax and shortening your candle’s lifespan. It’s usually caused by not burning the candle long enough the first time.

How to Fix a Tunneling Candle

1. Try the Aluminum Foil Trick

Wrap a piece of aluminum foil around the top of your candle, leaving a hole in the center for the flame. Light the candle and let it burn for about 1–2 hours. The foil helps trap heat, encouraging the wax to melt evenly across the top and reset the memory ring.

Candle memory is real! Your candle “remembers” how far it melted on the first burn—so that first light is everything.

2. Use a Heat Gun or Hair Dryer

If the tunnel is deep, use a heat gun or hair dryer on low to gently melt the top layer of wax. Once the surface is even, allow it to cool and set before lighting again. This can smooth out uneven wax and bring your candle back to life.

Pro tip: Keep the heat source a few inches away to avoid overheating or splattering.

3. Scoop and Reuse

If all else fails, scoop out the unmelted wax along the sides using a spoon or butter knife. You can repurpose this wax in a wax warmer to enjoy the fragrance. Waste not!

How to Prevent Tunneling in the Future

• Burn your candle long enough on the first use. Wait until the wax melts all the way across (usually 2–3 hours).
• Keep the wick trimmed. A ¼ inch wick ensures a steady flame without smoking or uneven burn.
• Avoid drafts. Wind or fans can cause uneven burning and tunneling.
