Fill a saucepan with water and bring to a boil. Turn off the heat and add a cup of white vinegar.
Meanwhile, preheat the oven to 160°C. Once it reaches that temperature, turn it off, place the saucepan with the mixture inside, and close the door.
The steam will work for at least three hours, softening the grease and leaving everything ready for a quick clean.
Mixture of baking soda, lemon, and vinegar
After the steam treatment, prepare a homemade paste by mixing 170g of baking soda , three tablespoons of warm water and the juice of half a lemon.
Apply this paste with a sponge to the oven surfaces, especially where there is stuck-on grease or black stains. Leave it on for 15 minutes.
