It is generally not safe to reuse pans or any cookware that was left in the oven during a self-clean cycle. The self-clean cycle in ovens is an intensive cleaning process that uses extremely high temperatures to burn off any accumulated food particles, grease, and other residues in the oven.
During the self-clean cycle, the oven temperature can reach around 900 to 1000 degrees Fahrenheit (482 to 538 degrees Celsius). This extreme heat can cause the residue on the pans or cookware to burn and release potentially harmful fumes and smoke. The fumes emitted during the self-clean cycle can be toxic and may pose health risks if inhaled or come into contact with food.
Additionally, the high temperatures during the self-clean cycle can also damage certain types of cookware, especially those with non-stick coatings, plastic or rubber handles, or any parts that are not designed to withstand such extreme heat.
To ensure safety and maintain the integrity of your cookware, it's best to remove all pans, pots, and other items from the oven before running the self-clean cycle. After the cycle is complete and the oven has cooled down, you can clean the cookware separately using appropriate cleaning methods and materials based on their specific material and finish.
