I have a stain in the microwave from a burnt potato where it smoked and caught on fire and burned up black. The walls inside the microwave have turned to another color, like a brown tanish color. This is inside a Sears Kenmore microwave.

I killed a microwave the same way. The question is not can you remove the stain from the microwave, you can't. You basically cooked the plastic until it was overdone, and now it's like a burnt cookie. My dad had a plastics business and I know whereof I speak.
The question is, can you safely use the microwave, or is it dead? I don't know the answer. (02/07/2010)
I used a vinegar, water, and lemon juice spray first then scrubbed the hard to get off spots with a paste of baking soda and water using a toothbrush. It worked pretty well. I then left a bowl of baking soda in the microwave for a few days, that helped with the smell. Good luck. (02/07/2010)
