Before you light your candle, make sure you trim the wick to about 1/4 inch EVERY TIME. This will keep your candle burning cleanly and help you get the most out of your candle.
Each time you light your candle, burn for a minimum of 2 hours, or until the melted wax pool reaches the edge of the glass. This will prevent wax tunneling.
Never leave your candle unattended.
