To store aluminum foil properly, keep it in a cool, dry place away from direct sunlight to prevent it from getting damaged or losing its shine. Use a foil box or a resealable plastic bag to store it, ensuring it's tightly rolled or folded to prevent tearing. Avoid storing it with sharp objects that could puncture the foil. If you're using a drawer, consider a foil liner or a designated compartment to keep it organized and protected.
