To clean your wax warmer, allow the wax to cool and harden completely, then turn off the warmer and unplug it from the outlet. You can then remove the hardened wax by gently pressing on one edge of the wax until it pops out of the warmer. If there is any remaining wax residue, you can wipe it out with a paper towel or cloth. Be sure to clean the warmer regularly to avoid buildup of old wax and keep it functioning properly.
