Best practice for busy clinics includes cleaning your paraffin wax warmer after every 25 treatments or the end of each day. Cleaning the paraffin wax warmers regularly eliminates the paraffin wax residue, debris, and dust. The routine also prepares you to start a fresh paraffin wax with the next melt. The paraffin wax should burn cleanly in the paraffin warmer without mingling with debris.
