Burn stains inside microwave
Acetone is not considered a carcinogen in the United States

The Material Safety Data Sheet can be found here.


It is the active ingredient in regular nail polish (varnish) remover.
It may remove the 'paint' from surfaces.
It is legally sold in the United States. 
It is highly flammable and explosive in the right concentrations. 


I would not recommend it to clean your microwave as it's hazardous to health if used improperly under a variety of conditions or used without proper safety equipment.

I would also advise against placing an aluminum foil pan in the microwave and turning it on.

Where did you get this misinformation, Connie?


  I have read that I can sprinkle baking soda, then add acetone (followed by liquid coffee) to remove these stains.


The above is incorrect!
