I Just did this it actually works! great for vase also! 1.Use and enjoy your candle. 2. When burned completely, remove excess wax and clean. a. If wax is cold, place in pot with shallow water and boil until wax is melted. b. Pour out excess wax and wipe clean with paper towel. Wash with soap and water. 3. Fill glass jar with goodies, store small items, or make your own candles.
