Abstract: A fluororubber wax-melting tray and a cleaning method thereof are disclosed. The fluororubber material of the disclosure is a synthetic polymer elastomer with high temperature resistance, corrosion resistance and low wear resistance. The fluororubber wax-melting tray has the same wax melting effect as the existing ceramic or metal wax melting trays. The shape of the wax melting tray is changed by the external force exerted by pushing the bottom of the fluororubber wax melting tray lightly. When both the external force tending to change the shape of the wax-melting tray and the adsorption force between the wax molecules are greater than the adsorption forces between the fragrance wax and the wax melting tray, the absorption force between a wax piece and the wax melting tray is released, and the whole solidified wax piece can be completely peeled off.
