Clean and inspect metal siding
Metal wall panels generally need little maintenance, but damaged finishes, incompatible fasteners and trapped contaminants can accelerate corrosion.
Recommended timingEvery 6–12 months
What to do
- Inspect panels, seams, flashings and fasteners for dents, looseness, coating damage, corrosion and contact with incompatible metals.
- Rinse loose soil and use mild soap with soft tools only when the panel or coating manufacturer allows it.
- Avoid excessive pressure, abrasive pads and unapproved solvents that can degrade or change the finish.
- Keep sprinklers, vegetation, deicing salts and wet debris away from the panels, and maintain sealant at openings and transitions.
- Use manufacturer-approved touch-up and repair methods; large dents, open seams or corrosion belong to a metal-cladding professional.
