When using aluminum foil for cooking or storing food, it's important to avoid wrapping acidic or high-sodium foods as they can corrode the foil. Also, refrain from using it with high heat, as aluminum foil can melt at temperatures above 450掳F (232掳C). Ensure the foil is clean and free from any manufacturing residues. Additionally, avoid using foil with non-stick cookware, as it can damage the non-stick surface. Always cut the foil to the appropriate size to prevent excess foil from touching the heating elements of your oven, which could cause a fire. Lastly, be cautious with sharp or pointed foods that could puncture the foil and lead to uneven cooking or potential burns.
