How do you remove burnt microwaved popcorn smell?

You can try baking soda, add a bit of water and turn it on for a minute or two, see if that helps. Or put the powder in there dry when not in use it can help the smell. By the way i think that is an aweful smell, My brother has done that a few times.

You could try going to the grocery store and getting either whole Cinnamon sticks or cinnamon extract and putting it in a dish of wash and boiling it out. You can leave the dish in the microwave until it evaporates. Bleach out the whole microwave first and then try this. It should get into the vents and clear out the smell.

Uggh! What a terrible thing. You can try wiping the microwave with vanilla essence (I used this method and it worked for me). OR Putting half a lemon in a bowl of water and berining to the boil in there and simer for 5 or 10 minutes. Or if all else fails - Nilodor (supermarket shelf in Australia) works on pretty much everything! You can get a spray one now too. Good luck! Let us know what eventually works.

Put 2 cups of water and 1/3 cup of vinegar into a bowl. Use some of this mixture to wipe down the inside walls of the microwave. Then place the bowl into the microwave and bring to a boil.

tried the lemon in water, candle scent in water, vanilla, and all sorts of fruits, spices, vinegars, etc., in water. No lessening of burnt smell in mircrowave. I tried the ground coffee (three times) treatment and the microwave smelled like an electric percolator that had boiled dry for several hours. Tried 409, Simple Green, Windex, spray-on air fresheners (odor removers) and they work for the moment, until the microwave is used again. Tried to disassemble the unit's casing to clean inside, but it (Kenmore) has Allen screws with nubbin sticking out so needs a special wrench not available at the hardware stores. Sears wants $100 bench fee just for a lookee-see, and a scheduler said it coulc cost another $100 to clean the oven (it works fine, just reeks like a burned down house). All this because an egg roll burned when set for 2 1/2 minutes which was okay if it had been frozen but it was thawed and burned, letting out clouds of black smoke before I finished changing the baby. All I know is to avoid heating water (comes out tasting burnt) in it and keep cleaning the interior before and after every use, and hope that with time the stink will ease off.

Try with the vinegar,boield in sole water
