How do I avoid getting metal shavings into my food when using aluminum foil facing?

To avoid getting metal shavings into your food when using aluminum foil facing, always handle the foil carefully to minimize tearing or scratching. Use a sharp knife or scissors to cut the foil, ensuring clean edges. Avoid using foil that is damaged or has sharp edges. When placing food on the foil, ensure the foil is smooth and free of any loose particles. Do not use foil with a non-stick surface for direct contact with acidic, salty, or high-sodium foods as it can cause the foil to break down. Finally, consider using heavy-duty aluminum foil which is thicker and less likely to produce shavings.
