<human>:  What is the best way to clean an oven?
<bot>: The best way to clean an oven is to start by taking out the removable parts like shelves and trays, and set them aside. Mix 1 cup of baking soda with 1 cup of white vinegar and a few drops of dishwashing liquid to form a paste. Spread the paste inside the oven and let it sit for an hour or two. Scrub the oven with a damp cloth or sponge to remove the paste and any baked-on food. Clean the removable parts separately with warm, soapy water, then put them back in the oven. Finally, wipe down the oven with a damp cloth and white vinegar.
