To store aluminum foil facing properly, first ensure that the foil is clean and dry. Roll it tightly starting from the shiny side, which should be facing outward. Secure the roll with a rubber band or a piece of tape. Store the roll in a cool, dry place, away from direct sunlight to prevent damage and to maintain freshness. Some people also use a paper towel tube to help keep the foil roll compact and prevent it from unraveling.
