5. Will aluminum panels rust over time? How should they be cleaned and maintained?
Release time:

Rusting: The aluminum composite panel substrate is made of aluminum alloy, which forms a dense oxide film on the surface, making it resistant to rust. However, if the coating is damaged (e.g., scratches exposing the substrate), prolonged exposure to rain may cause localized corrosion, requiring timely repainting. Daily Maintenance: ① Clean with a neutral detergent and a soft cloth (e.g., diluted dish soap). Avoid using strong acids/alkalis (e.g., toilet cleaner) or steel wool to prevent damage to the coating. ② Inspect outdoor panels every 1-2 years and repair any coating damage or aging sealant promptly.
