Candle tunneling happens when a candle burns down the center, leaving a ring of unmelted wax. Here’s how to prevent and fix it:
Aluminum Foil Method: Wrap foil around the top, leaving an opening for the flame, and let it burn for a few hours to melt the edges.
Hair Dryer: Melt the uneven wax using a hair dryer until the surface is level.
By following these tips, you’ll get an even burn and longer-lasting candles!
