5 Tips for Maintaining Aluminum Composite Panels

Phoenix Metals • January 10, 2025

Aluminum composite panels (ACPs) are commonly used in construction because they’re durable, versatile, and look great. However, they require routine maintenance to keep their structural integrity and appearance. 


Keep reading to learn five tips for keeping your ACPs in top shape.

Tip #1: Clean Regularly to Remove Dust and Debris

Following a regular cleaning routine can keep your ACPs looking good and prevent damage over time.


  • For large areas, such as the exterior of buildings, use a pressure washer on a low-pressure setting to remove accumulated dust and grime efficiently.
  • Avoid directing high-pressure streams too close to prevent damaging the protective coating.
  • More frequent cleaning may be necessary to keep panels looking pristine in areas prone to heavy pollution or near construction zones.


Soft cloths or sponges with mild detergent and water can be effective for smaller applications, spot cleaning, or interior panels where a pressure washer won’t quite work as well.


Tip #2: Check For and Remove Stains Promptly

Unaddressed stains can quickly compromise the appearance of aluminum composite panels.


  • Inspect panels regularly for stains caused by bird droppings, tree sap, or industrial pollutants.
  • Clean stains asap using a gentle, non-abrasive cleaning solution to avoid discolouration or permanent marks.
  • For tough stains, try using an isopropyl solution, but test it on a small area first to make sure it’s safe.


Tip #3: Inspect for Damage During Routine Maintenance

Routine inspections often catch issues before they escalate into costly repairs.


  • Inspect for physical damage, such as dents, scratches, or cracks — these can affect the panels’ integrity.
  • Peeling or bubbling on the coating could indicate weathering or improper installation, which you should address promptly.
  • Regular inspections are integral in areas with extreme hot or cold temperatures, high winds, or heavy precipitation.
  • Keep track of what you find, noting recurring issues which might indicate the need for additional protective measures.


Tip #4: Protect Panels From Harsh Chemicals

Improper cleaning methods can damage aluminum composite panels, but can be avoided by:


  • Skipping cleaners containing strong acids, alkalis, or solvents, as they can strip the protective coating.
  • Reading product labels and choosing solutions designed for aluminum or similar surfaces.
  • Test new cleaning agents on hidden panel sections to ensure it doesn’t cause discolouration or etching.


Tip #5: Schedule Professional Maintenance When Needed

Professional maintenance is recommended for areas that are difficult to access or require deep cleaning.


  • Professionals use advanced tools and methods to clean ACPs safely, even on high-rise buildings or complex structures.
  • Routine professional care can help restore panels to their original finish and prolong their lifespan.
  • This solution benefits businesses that want to maintain a professional exterior that reflects their brand's high quality.
  • Collaborating with experienced professionals ensures your panels receive the best care without risking damage.
