Step 1: Prep the area and gather your cleaning products
As with anything that involves heat, exercise caution and make sure that the oven is completely cooled down before starting. Use old towels to place on the floor in front of the oven to help catch any drippings that may fall as you clean. Next, pour white vinegar or lemon juice into a clean, empty spray bottle.
If your oven’s outer glass has thick buildup or residue, add ½ cup of baking soda in a bowl with 3 tablespoons of water and mix until it comes together to form a paste.
