Commercial oven cleaners contain harsh fumes. This method works as well with no ventilation concerns.

  1. Make a paste: half a cup of baking soda with a few tablespoons of water.
  2. Coat the inside of the oven, avoiding heating elements. Let sit overnight or at least 12 hours.
  3. Wipe away the dried paste with a damp cloth. It lifts grease and baked-on residue with it.
  4. Spray any remaining residue with white vinegar – it reacts with the baking soda to loosen it further.
  5. Wipe clean and dry.

Clean oven racks separately by soaking in a bathtub with hot water and dish soap for several hours.
