<human>:  What's the best way to clean an oven?
<bot>: The best way to clean an oven is to use a store-bought oven cleaner or make a paste of baking soda and water and spread it over the interior of the oven. Allow the paste to sit for at least an hour before scrubbing it off with a damp cloth or sponge. For tougher baked-on stains, you can use a paste of baking soda and vinegar.
