What are the best ways to clean aluminum foil facing that has become sticky or dirty?

To clean a sticky or dirty aluminum foil facing, start by removing any excess residue with a scraper or a plastic spatula. Then, mix a solution of warm water and dish soap, and gently scrub the surface with a soft cloth or sponge. Avoid abrasive materials that could scratch the surface. For stubborn stains, you can use a mixture of baking soda and water to create a paste, apply it to the area, and let it sit for a few minutes before scrubbing. Always rinse thoroughly and dry the surface to prevent further sticking. Regular cleaning can help maintain the cleanliness and functionality of your aluminum foil facing.
