On the first burn ensure the melted wax spreads the entire surface of the candle before extinguishing. Always trim the wick to a quarter of an inch—removing any dust debris or trimmings between burns. Candles should be placed on a heat-safe surface in a well-ventilated space and extinguished with a snuffer. Avoid expending all of the wax before replacing to protect the integrity of the container. Check packaging for any additional instructions.
