I love to recycle when I can, so all these used candle holders I had on hand were waiting to be cleaned and reused. Visit our blog for a step by step easy way to remove the wax and metal wick holder.
ETA: My tip is for store bought candle jars already filled with wax. After reading SEVERAL comments of popping it into the freezer, I tried it. I couldn't get the little metal tab out at the bottom. It took some very hot water to loosen the glue to remove it.
