If a forgotten sticker burns in the oven while a cast-iron pot is inside, it is unlikely to make the pot toxic. However, it may leave behind residue or odor on the pot, which can affect the taste or smell of the food cooked in it.
To address this situation, you can follow these steps:
- Allow the oven and the pot to cool down completely.
- Remove the pot from the oven and inspect it for any remaining sticker residue.
- If there is residue, use a non-abrasive scrub brush or sponge and warm, soapy water to gently clean the pot. Avoid using harsh chemicals or abrasive cleaners, as they can damage the cast iron.
- Rinse the pot thoroughly with water to remove any soap residue.
- Dry the pot completely to prevent rusting. You can towel dry it or place it in a warm oven for a short period to evaporate any remaining moisture.
- Once the pot is clean and dry, you can use it as you normally would for cooking.
It's worth noting that cast iron is a durable material, and it generally does not absorb or retain substances from the environment as long as it is properly cleaned and maintained. So, as long as you clean the pot well, any potential residue from the burnt sticker should be removed, and the pot should be safe to use for cooking.
