Remove oven racks and any elements inside.
Put on rubber gloves for protection.
Step 2: Creating the Baking Soda Paste
Mix half a glass of baking soda with a few tablespoons of water in a bowl.
Spread the paste on all oven walls, focusing on greasy areas.
Ensure thorough coverage, especially in corners.
Step 3: Allowing the Paste to Sit
Leave the baking soda paste on for at least 12 hours or overnight.
Clean oven racks during this time.
Step 4: Removing Residues
Use a damp cloth to wipe away the baking soda paste.
For stubborn residues, use a plastic spatula to carefully scrape them off.
Step 5: Enhancing Cleaning with White Vinegar
Pour white vinegar into a spray bottle.
Spray vinegar on the walls and let it sit for a few minutes.
Wipe with a damp cloth, adding water and vinegar if needed.
Step 6: Reassembling the Oven
Put oven racks and any removed elements back in place.
Your oven is now clean and ready for use.
Maintenance Tips:

Follow your oven’s manual for self-cleaning instructions.

Ensure proper ventilation during the cleaning process.
Stick to white vinegar for optimal cleaning results.
