You cleaned an old cast iron griddle in your self cleaning oven - did you ruin it?

Cleaning a cast iron griddle in a self-cleaning oven can potentially ruin it. Oven cleaners are extremely harsh and can remove the seasoning from the cast iron, which is essential for preventing rust and ensuring even heat distribution. The high temperature used in self-cleaning cycles can also damage the griddle by causing it to warp or crack.

Therefore, it is generally recommended to avoid cleaning cast iron griddles in self-cleaning ovens. Instead, use mild dish soap, warm water, and a soft sponge or brush to clean your cast iron griddle.
