1. One of my personal favorites is to clean and deodorize your microwave with lemon juice. Pour 1/2 cup of lemon juice into a small bowl and add about 1/4 cup of water. Place the bowl in the microwave and turn it on high for 3 minutes. When the microwave stops, do not open it. Instead, allow the bowl of lemon juice to sit in there for another 5 minutes before you open it. After 5 minutes, open the microwave and use a soft cloth to wipe out all the steam–and with it, the dirty gunk! You now have a clean, fresh smelling microwave. This even works wonders for stinky smells like burned popcorn.
