How do I remove oil stains from aluminum foil facing?

To remove oil stains from aluminum foil facing, first, let the stain dry completely. Then, use a mild detergent mixed with warm water to dampen a cloth and gently wipe the area. Avoid using abrasive cleaners or steel wool, as they can scratch the aluminum foil. For stubborn stains, you may apply a small amount of baking soda paste (baking soda mixed with water) and gently scrub with a soft cloth. Rinse thoroughly with water and dry the area. Always test cleaning methods on a small, inconspicuous area first to ensure no damage occurs.
