It is admittedly one of the most annoying sights to see when your candle starts tunneling. A total nuisance! Especially when you've invested good money for your favorite candles just to find them turning ugly and getting wasted. 🕯️ Unfortunately, this happens to any candles regardless of the price.

Time to stop missing out on your candles' full potential! Here are 5 simple and effective ways to fix it:

How to Fix Candle Tunneling

1. Use your handy hairdryer.

  • Turn your hairdryer on to the "Hot" or "Heating" option.
  • Direct the hot air towards the uneven sides of your candle.
  • Workaround this portion of uneven wax to spread it evenly.
  • Keep at it for a minute or two depending on the heat from your blower.

  • a hairdryer
    NOTE: Avoid pointing your blower to only one section for too long because you might burn the candle wick from prolonged overexposure to heat.

    2. Wrap an aluminum foil around your candle's vessel (The Foil Method).

  • Cut the appropriate amount of aluminum foil to completely cover the top of your candle jar
  • Wrap this tightly around your candle jar
  • Light your candle and allow the heat to spread
  • Aluminum foil will retain the heat inside longer and give enough time for the sides to melt

    3. Pop it into the oven for 2 minutes.

  • Heat for 2 minutes.

    NOTE: DO NOT put your candles inside a microwave oven! Candles usually have metal wick butts that can be dangerous when put inside a microwave oven.

    4. Get a candle topper.

    A candle topper is a nice accessory that typically works like TIP 2 - The Foil Method. It serves as an insulator to keep the heat equally distributed for the wax to melt all the way to the edge.

    It's better to prevent these things before it actually happens. There are 3 simple tips to avoid candle tunneling when you light your first scented soy candle (LUMI).

    How to Avoid Candles from Tunneling

    1. Leave your candles lit up for a minimum of two hours every time you light them up

    Let your candles burn 1-hour for every inch in diameter for easy trimming!

    2. Let your candles create a wax pool

    Allow your candles to heat up until the wax is melted all the way across the edge of their containers. This creates a flat surface on the top layer.

    3. Place your candles away from fans or where the air is blowing

    The flame should be staying still and pointed upwards to ensure even heat distribution and melting!
