After dinner, briefly air out, let the oven cool down, and while enjoying a cup of tea, apply a simple paste to the grime. The routine is deliberately kept relaxed and fits into any evening.
Mix a teaspoon of baking soda with some water to form a paste, apply it to the dirty spots and let it work for about 30 minutes. Afterwards, a damp cloth is enough to wipe off the loosened dirt effortlessly.
