When the wick is short and the last bit of wax is sitting on the bottom of a candle jar, you may be tempted to simply throw it away. But cleaning out the container is as easy as boiling water. Then you can reuse it however you'd like.
Start by filling your candle jar almost to the top with boiling water (photo 1). Let the water sit for a couple of minutes to loosen up the wax, then use a butter knife to score the wax and scrape the edges. The wax should pop to the surface (photo 2); discard it in the trash. To get the jar sparkling clean, simply wash it with dish soap (photo 3). It's a good idea to do this over a bowl so as not to get any wax down the sink.
