clean wax with slow cooker

I retired my solar wax melter and use a slow cooker exclusively to clean wax.  For safety, I operate the slow cooker outdoors and place concrete pavers beneath the hot appliance and wood table top. After crush and strain honey extraction, wax from thirteen frames are rinsed in warm water and cleaned in two slow cooker batches.   I added half the wax and two cups of water to the large oval slow cooker. Shown is cotton fabric and blue tape which suspend the wax above the water bath.  After two to three hours on the high setting, I turn off the slow cooker and leave all components (lid, cotton fabric and wax impurities) undisturbed until the slow cooker has completely cooled.
