<human>:  How do I clean a microwave oven?
<bot>: To clean a microwave oven, start by removing any food and debris. Then, mix a solution of 1 cup of water and 2 tablespoons of lemon juice, baking soda, or vinegar in a microwave-safe bowl. Place the bowl in the microwave, and turn the oven on for about 2 minutes. Remove the bowl, and wipe the interior with a damp cloth or sponge. To finish, use a dry cloth to remove any remaining moisture.
