The best cleaning methods for aluminum foil facing involve gentle cleaning to avoid damaging the foil. Use a soft cloth or sponge with warm water and mild dish soap to wipe the surface. Avoid abrasive cleaners or scrubbing, as this can scratch or tear the foil. For stubborn stains, a mixture of baking soda and water can be applied as a paste and gently rubbed with a soft cloth. Always rinse thoroughly and dry the surface to prevent water spots and maintain the integrity of the aluminum foil.
