Yellow interior of microwave after fire

I had a fire in my microwave due to my negligence. Smoke billowed out and when it finally stopped I opened the door and the interior walls of the microwave had turned yellow. Is there now a danger when using it. I was unable to clean the surface with soap and water.
Thanks you

Hi, Leslie. I wouldn't use it. Microwaves are not heirlooms that are irreplaceable, and they're not even terribly expensive when prorated over several years of life. Microwave ovens must seal effectively to prevent danger to you and it is very hard for anyone to assure you that the fire was not bad enough to compromise the fit or a gasket.
