Aluminum foil facing requires gentle cleaning to avoid scratching the surface. Use a soft cloth or sponge with warm water and mild dish soap to clean the surface. Avoid abrasive materials like steel wool or harsh chemicals, as they can damage the aluminum. After cleaning, dry the surface thoroughly to prevent water spots. For stubborn stains, a mixture of water and white vinegar can be used, but always test on a small, inconspicuous area first. Regular cleaning will help maintain the appearance and functionality of aluminum foil facing.
