How to Stop a Candle from Tunneling

Ever lit a candle, only to find that it starts burning down the center, leaving a ring of unused wax around the edges? This frustrating phenomenon is known as "candle tunneling," and it can happen to even the best of candles. Not only does this waste wax, but it also impacts the candle’s fragrance and burn time. Fortunately, there are easy steps you can take to stop your candles from tunneling and get the most out of every burn.

• 1. Burn the Candle Long Enough on First Use
• 2. Trim the Wick Regularly
• 3. Keep Candles Away from Drafts
• 4. Don’t Burn for Too Long
• 5. How to Fix Tunneling Once It Happens

1. Burn the Candle Long Enough on First Use

One of the most important things to remember is that the first burn is crucial to preventing tunneling. When you first light a candle, allow it to burn for at least 2-4 hours, or until the wax has melted all the way to the edges of the container. This creates an even wax pool, setting the foundation for a consistent burn every time. Skipping this step can lead to tunneling, as the candle will "remember" the shape of the wax pool and burn that way each time.

2. Trim the Wick Regularly

A wick that’s too long can result in a large, uneven flame. This can melt the wax too quickly in the center and cause tunneling. Before lighting your candle, trim the wick to about 1/4 inch (0.6 cm). This will help keep the flame small and controlled, ensuring an even burn. Additionally, regularly trimming the wick throughout the burn process helps to minimize soot buildup and keeps the candle from flickering too much.

3. Keep Candles Away from Drafts

Drafts from windows, vents, or air conditioning can cause your candle’s flame to flicker and burn unevenly, leading to tunneling. Make sure to place your candle in a stable, draft-free area to ensure the wax melts evenly. A steady flame not only helps prevent tunneling, but it also gives your candle the best chance to release its fragrance throughout the room.

4. Don’t Burn for Too Long

While it's important to let your candle burn long enough on the first use, burning a candle for too long can also contribute to tunneling. A candle that burns for more than 4 hours in one go may create uneven heat distribution, which can lead to tunneling. After 4 hours, allow your candle to cool and solidify before lighting it again. This will ensure a consistent burn and prevent wax from melting unevenly.

5. How to Fix Tunneling Once It Happens

If tunneling has already occurred, don’t panic! You can fix it. First, gently scrape off the excess wax from the sides of the candle (while it’s cool and hard) to make sure the wick is centered. Then, you can use a heat gun or a hair dryer to re-melt the wax and let it pool evenly. If you don’t have a heat gun, you can also place the candle in a warm oven (at a low temperature) to re-melt the wax evenly.

Another option is to use a "candle topper" or "candle lid" that helps trap heat and promote even melting. These can be especially useful for large candles that tend to tunnel easily.
