I seriously burned popcorn in the microwave last night. A PLUME of yellow smoke when we tried to open it. Had a fire extinguisher out and everything in case. No fire, but bad smoke and smell. Now the house reeks of burned popcorn and butter, and the microwave is stained yellow! Any ideas on how to get rid of the smell and the coloring? I already tried bringing a cup of water with some lemon juice to a boil but it didn't help.
