The decorative jar is often the main reason we purchase a candle, but removing the wax so the jar can be reused sometimes feels like an impossible task. Instead of chipping away at the wax to no avail, turn to the microwave for the solution. First, use a knife to remove as many of the large wax chunks from the jar as you possibly can. Then, checking first to make sure that the jar is microwave-safe, put it in the microwave for about 20 seconds. This will melt the wax so you can just use a paper towel to wipe it clean.
