To store aluminum foil facing after use, first, wash and dry it thoroughly to remove any residue. Roll it up tightly, starting from the end that has been used, to keep the cleanest part of the foil on the outside. You can also use a rubber band or a piece of tape to secure the roll. Store it in a cool, dry place, away from direct sunlight to prevent it from losing its shine and becoming brittle. If you have a dispenser, you can also reinsert the foil back into the dispenser for neat and organized storage.
