Once there is 1cm of wax left in your candle, blow it out and let the wax set.

Half fill a heatproof bowl with hot water (not boiling, boiling water with a splash of cold works best).

Place your candle vessel in the bowl. The edge of the wax will start to melt. When this happens, gently press down on the edge of the wax and take it out.

Remove any excess wax with a paper towel. Once all wax has been removed, wash the vessel with warm soapy water.

Place an Analogy refill into your clean vessel.

Strike a match, light your candle, and enjoy.
