How do you get burnt popcorn smell and stains out of the inside of a microwave?

I burned a bag of popcorn – BIG TIME. The smoke alarm didn’t go off. What was once a really white interior is now brownish yellow!! And it smells! I tried baking soda and it hasn’t worked, nor any kind of soapy cleaner. Just now getting the house aired out and smelling normal again. YUK!
