How to Fix Candle Tunneling: A Complete Guide

Candle tunneling is one of the most frustrating issues candle lovers face. It occurs when only the wax around the wick melts, creating a tunnel while leaving a thick outer ring of unmelted wax. This not only shortens the lifespan of your candle but also prevents you from fully enjoying its fragrance and ambiance.

If you’ve ever been disappointed by a candle that won’t burn evenly, don’t worry—you’re not alone. The good news is that candle tunneling can be prevented and even fixed. In this guide, we’ll explain what causes tunneling, how to avoid it, and the best ways to rescue a candle that has already tunneled. By following these steps, you’ll get the most out of your candles and enjoy a smooth, even burn every time.

What Is Candle Tunneling?

Candle tunneling happens when the flame burns straight down the middle of the candle, leaving a ring of hard wax around the edges. Over time, this wasted wax builds up, reducing the total burn time of your candle. The deeper the tunnel gets, the harder it is for the flame to stay lit, eventually making the candle unusable.

This problem is especially common with cheaply made candles, but even high-quality soy candles can tunnel if they’re not burned correctly. The good news? With proper candle care, you can prevent tunneling from happening in the first place.

What Causes Candle Tunneling?

Several factors can contribute to candle tunneling. Understanding these causes can help you prevent this issue and extend the life of your candles.

1. Wick Size

A wick that’s too small for the candle won’t generate enough heat to melt the entire surface of the wax. This results in a narrow burn pool, leading to tunneling.

2. First Burn Memory

Wax has memory, meaning it remembers how far it melted during the first burn. If the initial burn is too short, the wax will continue following that pattern in future burns, causing a tunnel to form.

3. Drafty Environments

Burning a candle in a breezy or cool area can cause an uneven burn. Drafts push the flame to one side, leading to uneven melting and eventual tunneling.

4. Poor Wax Quality

Low-quality paraffin candles often contain fillers and additives that don’t burn efficiently. Soy wax candles, like those from Aarka Origins, offer a cleaner, more even burn, making them a better choice for avoiding tunneling.

How to Prevent Candle Tunneling

If you love candles, knowing how to prevent tunneling is essential. Here are some simple steps to ensure your candles burn evenly and last longer.

1. Burn Your Candle Long Enough the First Time

The first burn is the most important. Make sure you let your candle burn until the entire top layer of wax is melted. This usually takes one hour per inch of candle diameter.

For example:

  • If your candle is 3 inches wide, you should let it burn for at least 3 hours on the first use.

  • If it’s 4 inches wide, burn it for 4 hours.

2. Trim the Wick to ¼ Inch Before Each Use

Keeping the wick at ¼ inch ensures a steady flame and prevents excessive soot or high flames, which can cause tunneling.

3. Avoid Drafts

Place your candle in a stable, draft-free environment to prevent the flame from flickering and burning unevenly.

4. Choose High-Quality Soy Candles

Soy candles, like the Faerie Door Soy Candle, burn cleaner and more evenly than paraffin candles, reducing the chances of tunneling.

How to Fix a Candle That Has Already Tunneled

If your candle has already started tunneling, don’t worry! You can still fix it and get an even burn. Try these methods to restore your candle:

1. The Aluminum Foil Method

The foil tent trick is one of the easiest ways to fix tunneling.

How to do it:

  1. Light your candle.

  2. Wrap a piece of aluminum foil around the top, creating a tent.

  3. Leave a small hole at the top for air to escape.

  4. Let the candle burn for 1–2 hours.

  5. The foil will help trap heat, melting the outer wax and evening out the surface.

2. The Hair Dryer or Heat Gun Method

If the tunneling is mild, you can use a hair dryer or heat gun to melt the top layer of wax.

Steps:

  • Turn the hair dryer on high and direct the heat over the hardened wax edges until it melts evenly.

  • Let the wax settle before relighting the candle.

3. The Oven Method (For Severe Tunneling)

If your candle has deep tunneling, the oven method may be the best fix.

How to do it:

  1. Preheat your oven to 175°F (80°C).

  2. Place the candle on a baking sheet and put it in the oven for 5–10 minutes.

  3. Once the top layer of wax is evenly melted, carefully remove it from the oven.

  4. Let the wax cool and solidify before relighting.

4. Remove Excess Wax

If a tunnel has already formed, you can carefully scrape off the excess wax around the edges using a butter knife or spoon.

5. Replace the Wick (Last Resort)

If none of the above methods work, you may need to replace the wick. This involves melting the wax, removing the old wick, and inserting a properly sized wick before letting the wax harden again.

Tips to Get the Most Out of Your Candles

To ensure a long-lasting, clean burn, follow these extra tips:

✅ Keep Your Candle Clean

Dust and debris can clog the wick and cause uneven burning. Keep your candles covered when not in use.

✅ Use a Candle Snuffer Instead of Blowing It Out

Blowing out a candle can cause the wick to smolder and create smoke. Using a candle snuffer helps prevent soot buildup and extends the candle’s life.

✅ Burn in 2–4 Hour Increments

Let your candle burn for at least 2 hours but no more than 4 hours per session. This helps prevent tunneling and extends the life of the candle.

✅ Store Candles Properly

Keep candles away from direct sunlight and extreme temperatures to preserve their fragrance and shape.

For a long-lasting, high-quality burn, try the Halfling Meadow Soy Candle for a fresh, nature-inspired scent or the Afternoon Tea Soy Candle for a cozy, relaxing ambiance.

Choosing the Right Candle to Avoid Tunneling

Not all candles are created equal! If you want to prevent tunneling from the start, selecting a high-quality candle with the right wick and wax type is essential.

Here’s what to look for:

1. Opt for Soy or Beeswax Candles

Paraffin candles often contain fillers and synthetic additives that burn unevenly, increasing the chances of tunneling. Instead, go for:

  • Soy wax candles (cleaner burn, longer-lasting)

  • Beeswax candles (natural burn, minimal soot)

Aarka Origins offers hand-poured soy candles, like the Firewood & Vanilla Soy Candle, which burns evenly and provides a warm, comforting scent.

2. Check the Wick Size

A properly sized wick ensures the entire surface of the candle melts evenly. If the wick is too small, it won’t produce enough heat to melt the wax evenly, leading to tunneling.

For wide candles, look for:

  • Multiple wicks (to distribute heat evenly)

  • Thicker wicks (to support wider candles)

The Halfling Meadow Soy Candle is a great example of a well-designed candle with the right wick-to-wax ratio for a clean, even burn.

3. Choose Well-Made, Hand-Poured Candles

Mass-produced candles often have poorly centered or improperly sized wicks. Hand-poured candles, like those from Aarka Origins, are carefully crafted to burn evenly and last longer.

More Advanced Candle Troubleshooting

If you’ve already tried fixing your tunneled candle and it’s still not working, here are a few additional techniques:

1. Level the Wax with a Spoon or Knife

If the wax has built up unevenly, use a spoon or butter knife to gently scrape away the excess wax from the tunnel’s edges. This will help the flame access fresh wax and burn more evenly.

2. Use a Candle Warmer

If your wick is too short to relight, but there’s still plenty of wax left, consider using a candle warmer. This allows you to enjoy the fragrance without burning the wick.

3. Add a New Wick (If Needed)

For severely tunneled candles, you may need to insert a new wick to restart the burning process. This is a more involved fix but can save an expensive or sentimental candle.
