Burnt popcorn in microwave

[GloryHunter]

My son left his popcorn in the microwave for too long
Came in from work to an acrid smokey smell permeating through the house. How on earth do I get rid of the smell? I've had Windows and doors open for as long as I could bear the cold. Please, any idea?

Scented candle?

Try half a lemon in a bowl of water in the microwave for 5 mins. Will need to wipe the inside down after.

Thank you I will try both suggestions.
