When using aluminum foil with a nonstick coating, it's important to avoid exposing it to high heat as the nonstick layer can degrade and release harmful fumes. Do not use it in broilers, on grills, or in the oven at temperatures exceeding 400掳F (204掳C). Additionally, refrain from cutting or puncturing the foil, as this can damage the nonstick surface. Avoid using metal utensils that might scratch the coating. Always follow the manufacturer's guidelines for safe use and temperature limits.
