For cleaning aluminum foil facing after use, it's best to use gentle, non-abrasive cleaning products. Mild dish soap and warm water are usually sufficient for most cleaning needs. Avoid using harsh chemicals or abrasive scrubbers, as they can damage the aluminum surface. If there are stubborn stains, a mixture of baking soda and water can be used as a gentle abrasive. Always rinse thoroughly and dry the surface to prevent any residue or potential damage.
