Clean Melted Plastic From Cast Iron

Plastic changes from a solid to a liquid when subjected to heat. This chemical process can be witnessed firsthand when a plastic spoon or bag comes in contact with a hot cast-iron object such as a pan. What is left after the encounter is a melted mess that is very difficult to remove. When allowed to cool, the plastic hardens to its original state and remains stuck to the cast-iron pan.
