Clean the oven with baking powder paste
Stubborn crusting in the oven or in the microwave, you can solve super with baking soda.
I take a packet of commercial baking powder from the discounter, put it in a small bowl and add 3 tablespoons of mineral water (tap water is also!).
Mix the ingredients to a pulp and add to the dirt. Leave to soak for about 30 minutes (depending on the level of soiling) and rub with a damp cloth. Your oven should be clean now.
