upon hours scrubbing your oven clean? Stop it! Instead, make a paste using water and baking soda and spread it all around the inside of your oven. Let it sit overnight, and then take a wet rag to wipe out as much of the baking soda mixture as possible. Next, spray some vinegar on the inside of your oven and wipe down with a wet rag. Then turn your oven on low for about 20 minutes to let it dry.
