Pop the jar in a shallow bowl of boiling hot water for 10 to 20 seconds, make sure do not overfill the bowl. The water should be just just reaching the bottom of the jar.

Wiggle and remove the softened wax. Use a paper towel to soak and remove any melted wax. 

Wash out any residue wax using warm soapy water with a cloth or paper towel.

Now pop in one of our candle refills. Enjoy.
