I don’t even think about scrubbing my dirty oven anymore: a friend taught me this trick and now it’s as good as new, simply!

Dip the sponge in the prepared mixture and apply it to the entire  oven surface (no need to rub, just moisten).
Soak a few sheets of  kitchen paper in the prepared mixture and place them on the oven surface.
Place the moistened  paper towels on the oven door glass and let them sit.
In the meantime, you can use the leftover mixture to clean the pot.
After half an hour, put it back in the oven, remove the kitchen paper and rinse it with clean water using a sponge.
Finish by drying the oven thoroughly with a clean, dry cloth.
After cleaning, turn the oven on to the highest setting and leave it on for a while.
To clean the grill, you can use a small piece of a detergent tablet to make it easier to remove dirt.
