BOO, lol! Hey Amber, try microwaving a bowl of water with half a lemon in it for 30seconds-1min. Then give a wipe down with antibac spray. My partner microwaves Scotch pies, and the smell is unreal!

The best way is to put a saucer of bicarbonate of soda in the microwave overnight which neutralises the odour. I keep it in the microwave whenever it's not in use.
