I understand how unsightly and frustrating food stains can impact the appearance of your appliance. I would recommend that you consider repair. You would be responsible for the labor charges for the tech to disassemble, clean and reassemble the door. For further assistance, please reach out to our technical social media support team via private message on Facebook or Twitter via @LGUSSupport and use #VOC in your first message to our social media support team or call at 800-243-0000. Also, be sure to provide your contact information, model/serial numbers and date of purchase along with a brief description of the issue and we will schedule a visit. Thank you. ^Jennifer
