Step 1: Prep area and supplies
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, add ½ cup of baking soda in a bowl with 3 tablespoons of water and mix until it comes together to form a paste.
Step 2: Spread paste on glass
Open the oven door to get access to the interior glass. Using either a brush or a flexible spatula, spread the baking powder paste on the glass, covering the entire surface. Leave the mixture on for at least 20 minutes or longer depending on the level of soil baked on the glass.
For extra cleaning power, mix one part vinegar or lemon juice with one part water and spray on top of the baking soda paste with a spray bottle. It’s normal to see some bubbling or fizzing during this step.
Step 3: Wipe with microfiber cloth
Once you're ready to remove the paste, wet a clean microfiber cloth with some warm water and begin wiping the baking soda off in a circular or downward motion. Repeat until the baking soda has been completely removed.
If any baked-on grease is still present, you can use a plastic scraper to lift off any residue that wasn't removed with the baking soda paste.
Step 4: Finish with the lemon juice or vinegar mixture
Spray the vinegar or lemon juice mixture on the interior and exterior glass of the oven and wipe with a clean microfiber cloth. Once all grime has been removed, you can buff any leftover streaks with a dry microfiber cloth.
