<human>:  What is the best way to clean a greasy oven?
<bot>: The best way to clean a greasy oven is to use a mixture of warm water and baking soda. Start by sprinkling the baking soda on a damp cloth, then scrub the oven walls. Once the surface is covered, let it sit for about 15 minutes. Then, use a damp cloth to wipe away the baking soda. Finish by using a clean cloth and warm, soapy water to scrub away any remaining dirt or grease. Finally, rinse with clean water and dry thoroughly.
