How do I clean aluminum coil?

To clean an aluminum coil, start by using a soft cloth or sponge dampened with warm water and mild dish soap. Gently wipe the coil to remove dirt and grime. Avoid abrasive materials or harsh chemicals that could scratch the surface. After cleaning, rinse the coil thoroughly with clean water to remove any soap residue. Dry the coil completely to prevent water spots or corrosion. For stubborn stains, consider using a specialized aluminum cleaner, but always follow the manufacturer's instructions and test on a small area first.
