To store aluminum foil properly and make it last longer, keep it in a cool, dry place away from direct sunlight. Use a foil container or a resealable plastic bag to store it. Avoid stacking heavy items on top of it to prevent crushing. When using, always cut the foil from the end to minimize exposure to air, which can cause it to oxidize and weaken. Additionally, you can use a paper towel to wipe the foil before storing to remove any food particles that might cause it to stick together or degrade in quality.
