Take out the oven racks to access the interior easily.
Place the racks on old towels or newspapers to avoid transferring grime to other surfaces.
Remove any items in the oven, such as pans or thermometers.
Step 3: Make the Homemade Oven Cleaner
Mix equal parts baking soda and water to create a spreadable paste (start with ½ cup each).
Stir until the paste reaches a smooth consistency.
Step 4: Apply the Cleaning Paste
Spread the baking soda paste all over the inside of the oven, avoiding the heating elements.
Apply a thicker layer of paste to areas with heavy grime.
Step 5: Let the Paste Sit & Clean Other Areas
Let the paste sit for 12 hours or overnight.
While waiting, soak the oven racks in a bathtub with hot water and ¼ cup of Castile soap for a few hours.
Clean the stovetop and knobs while the oven cleaner sets.
Step 6: Wipe Away the Paste
After the paste has sat, use a damp cloth to wipe it off.
For stubborn spots, use an old toothbrush but avoid harsh scrubbing tools like scouring pads to protect the surface.
Step 7: Spray Vinegar for Final Clean
Fill a spray bottle with white vinegar.
Spray the inside of the oven, which will cause any remaining baking soda to foam up, making it easier to clean.
Step 8: Clean the Oven Glass
Apply another batch of baking soda paste to the inside of the oven glass.
Let it sit for 30 minutes, then wipe with a damp cloth.
For a finishing touch, clean the exterior with glass cleaner for a shiny, spotless finish.
Your oven will be clean and fresh without any harsh chemicals!
