Remove wax from holders by running very hot water over them. Candles will fade if left in the light for an extended time. Never put candles in a window or directly expose to bright outdoor light or indoor spotlights. Candles should always be burned in proper candle holders or bases. Never leave candles burning unattended.
Accidents do happen.
Extinguish candles when they get within 2 inches of their holders or decorations. When blowing out a candle, hold your finger in front of the flame and blow at it. The air will flow around the finger and extinguish the candle from both sides. This will prevent hot wax from spattering.
