Introduction
Aluminium composite panels (ACPs) are known for their durability, modern appearance, and low maintenance needs. However, like all exterior or interior finishes, they still require periodic cleaning — especially in polluted urban areas or coastal zones. The key is to clean them without scratching, fading, or damaging the surface.
In this guide, we’ll show you how to clean aluminium composite panels correctly using safe, recommended techniques and products.
Why Proper Cleaning Matters
ACP surfaces are coated with protective finishes such as PE (Polyester) or PVDF (Polyvinylidene Fluoride). These coatings maintain the panel’s:
- Gloss and color retention
- UV resistance
- Corrosion protection
Using harsh chemicals or abrasive tools can strip these coatings, causing permanent damage. Proper cleaning extends the panel’s life and preserves its sleek finish.
How Often Should You Clean ACPs?
The frequency of cleaning depends on the environment:
- Every 6–12 months for urban and industrial zones
- Every 3–6 months in coastal or high-pollution areas
- Annually for interior applications or low-dust regions
Step-by-Step: How to Clean Aluminium Composite Panels
- Rinse with Clean Water
Use a low-pressure hose to remove loose dirt and dust. Avoid high-pressure washers unless specifically recommended by the panel manufacturer.
- Prepare a Mild Detergent Solution
Use a soft cleaning agent diluted in warm water.
Recommended cleaners:
- pH-neutral dish soap
- Car shampoo
- Diluted glass cleaner
Avoid: Strong acids, alkalis, bleach, ammonia, or abrasive powders.
- Wipe Using a Soft Sponge or Microfiber Cloth
Gently scrub the surface in straight strokes. Do not use steel wool, hard brushes, or rough fabrics. Always test a small, inconspicuous area first.
- Rinse Thoroughly with Water
Remove all detergent residue with fresh water. Leftover soap can leave streaks or attract more dirt.
- Dry with a Soft, Lint-Free Cloth
To avoid water spots, dry the panels with a clean microfiber towel or soft chamois.
Common Mistakes to Avoid
- Do not use abrasive materials such as scouring pads or stiff brushes.
- Avoid strong solvents like acetone or paint thinners — they can damage the surface.
- Never use pressure washers too close to the surface, as they can lift the coating.
- Avoid circular rubbing motions which may leave swirl marks.
Optional: Protective Maintenance Coating
For high-end finishes or panels in harsh environments, you can apply a non-abrasive automotive wax or protective sealant (recommended by the panel supplier). This can enhance water repellency and keep the surface cleaner for longer.
Final Thoughts
Cleaning your aluminium composite panels the right way helps maintain their beauty and extends their life. With just a little care, ACP surfaces can continue to look sharp, vibrant, and professional for years — whether used for cladding, signage, or interior panels.
If you’re unsure about which finish you have (PE or PVDF), always refer to the manufacturer’s cleaning guidelines.
