Mix the baking soda with enough water to form a thick paste.
Apply to Oven Interior
Spread the paste on all dirty surfaces of the oven, avoiding heating elements.
Focus on areas with grease or burnt-on residue.
Let it sit overnight (or at least 8–12 hours) for maximum effect.
Spray Vinegar
Put white vinegar in a spray bottle and lightly mist the areas covered with baking soda.
The vinegar will react with the baking soda, helping to lift grime.
