7. Dry and evaluate the result:

Dry the surfaces thoroughly with a dry cloth and evaluate the result. If necessary, repeat the cleaning process to remove any remaining residue.

8. Periodic cleaning:

To keep your oven clean, perform this cleaning with Marseille soap periodically, especially after cooking fatty dishes or when you notice burnt residue forming.

If you don’t have Marseille soap available
A great alternative to Marseille soap is baking soda. Mix a few tablespoons of baking soda with water until you get a spreadable paste. Apply this paste evenly to the inside surface of the oven, focusing on areas with burnt oil encrustations.

Let the baking soda paste sit for at least 30 minutes or more, so it can work on the buildup and soften it. After that time, use a damp sponge or cloth to gently remove the paste, along with the softened burnt oil. You may need to do a little bit of work to completely remove stubborn buildup.

Finally, rinse the oven thoroughly with clean water and dry it with a dry cloth.

In conclusion, Marseille soap is a natural and effective solution to remove burnt oil from the oven. By following this guide, you can keep your oven clean and in tip-top condition without the use of harsh chemicals.
