The best way to clean your aluminum foil facing after use is to gently wipe it with a damp cloth to remove any residue. Avoid using abrasive materials as they can scratch the surface. After cleaning, let it dry completely. To store, roll it up tightly or fold it neatly, and keep it in a cool, dry place away from direct sunlight to prevent any damage or discoloration. Use a resealable plastic bag or a designated container to protect it from dust and moisture.
