To clean aluminum foil facing after use, first let it cool down to avoid burns. Then, gently scrape off any food residue with a plastic scraper or the edge of a credit card. Avoid using metal scrapers as they can scratch the surface. Wipe the surface with a damp cloth and mild dish soap to remove any grease or grime. Rinse with warm water and dry thoroughly. For stubborn stains, you can use a mixture of baking soda and water to create a paste, apply it to the stain, let it sit for a few minutes, then scrub gently and rinse. Always check the manufacturer's instructions for any specific care requirements.
