What is the best way to clean out a yankee candle so you can reuse it?

I've filled the jar with hot soapy water and most of the wax will flow away, after if I want to use it for food items I put it through a hot wash in the the dishwasher.

If you're speaking of a Yankee candle jar the best way to clean the wax out is to put the jar in the freezer and the wax will get hard then take it out and I usually stick a knife down in the jar to break the wax up and once broken just dump the wax out, then clean your jar well with hot water and dish detergent and you should be good to go.

Use a sharp knife to remove the wax and raise the wick for use.

I turn on hot water and run it over the jar. After a few minutes the wax just pops right (you may need to help it a little) out and the jar can be scrubbed and reused.

Burn down as far as possible. Take out what comes out easy. Put in freezer. big chunks should come out easy. Then wash in very hot water.
