The procedure to follow
1. Preheat the empty oven to 100 °C: gentle heat will activate cleaning.
2. Place the tablet on a baking tray and pour a drizzle of hot water to melt it.
3. Crumple an aluminum foil and place it directly on the most dirty areas. It will act as a dirt magnet and remove residue.
4. Leave on for about two hours: the tablet dissolves the fat deeply.
5. Remove the aluminum, wipe with a damp sponge... and admire: the dirt magically disappears!
