Human: What is a good way to clean a dirty oven? Assistant: 
A good way to clean a dirty oven is to use baking soda and water. Mix 1/2 cup of baking soda with 2 cups of warm water, then spray it onto the inside walls of the oven. Let it sit for 15 minutes, then scrub with a damp cloth or sponge. Rinse with warm water and dry thoroughly.
