10 Ways to Maintain Aluminium Shutters

Have you recently invested in aluminium shutters for your balcony or high-rise apartment and want to keep them looking and functioning at their best? Maintaining outdoor shutters is a practical way to protect your investment while preserving the appearance and performance of your building exterior. Regular upkeep not only supports smooth operation but also helps reduce the likelihood of premature wear, corrosion, or mechanical issues caused by coastal weather conditions. Whether you're dealing with strong sun, salty air, or seasonal storms, proper maintenance can go a long way in retaining durability and aesthetic appeal.

In this blog, we’ll share 10 easy and effective tips to help you maintain aluminium shutters on the Sunshine Coast and extend their lifespan.

1. Clean with Mild Soap & Water

Over time, airborne particles, sea salt, and dust can settle on external aluminium shutters. Regular cleaning helps prevent build-up and surface deterioration.

• Use a soft cloth or sponge with a solution of mild soap and warm water.
• Rinse with clean water to remove soap residue.
• Avoid abrasive scrubbers or harsh chemicals, which may damage the powder-coated finish.

Cleaning once every two to three months is usually sufficient in most Sunshine Coast environments.

2. Inspect for Debris in Tracks & Hinges

If your aluminium shutters are bifold or sliding, check that the tracks and hinges are free from dirt and debris. Built-up particles can cause the shutters to jam or wear prematurely.

• Use a soft brush or cloth to wipe out grit and leaves.
• Avoid using sharp tools that could scratch or bend the track components.
• Regular inspections make it easier to keep moving parts in good working order.
• Also, check for signs of discolouration, especially around joints or fasteners, as this may indicate trapped moisture.

Keeping these areas clean supports smoother movement and helps avoid long-term mechanical issues that may require professional repairs.

3. Lubricate Moving Component

Smooth operation is essential for externally mounted shutters, especially on balconies and patios where exposure to the elements is consistent.

• Apply INOX MX3 spray lubricant to hinges, joints, flush bolts and any sliding mechanisms.
• Wipe away excess to avoid attracting dust and dirt.
• Lubrication every 4–6 months helps maintain ease of use and prevents corrosion on contact points.
• Pay extra attention to high-use areas or shutters exposed to salt air, as these parts may need more frequent care.

Avoid using oil-based lubricants, as they can become sticky over time and contribute to build-up, reducing the shutter’s functionality.

4. Tighten Loose Screws or Fasteners

With outdoor exposure and regular use, minor loosening of screws or fixings can occur. A simple maintenance step is to inspect and retighten these elements.

• Check fasteners holding shutters to walls or frames.
• Use a screwdriver to carefully secure loose components.

Addressing loose fittings early can prevent larger issues like misalignment or rattling.

5. Rinse After Storms or High Winds

After severe weather, aluminium shutters may be left with residue from rain, dirt, or salt spray—especially in coastal locations like the Sunshine Coast.

• Rinse thoroughly with clean water to remove salt and grit.
• Allow to air dry or gently towel dry with a soft cloth.

Post-storm rinsing helps preserve both appearance and material condition.

6. Check Drainage Around the Base

Improper drainage can cause water to pool around the lower track or fixings of your shutters. Moisture build-up may affect their performance and mounting points over time.

• Confirm that the balcony drains are unblocked.
• Look for pooling near shutter tracks and gently redirect water flow if needed.

Maintaining proper water run-off extends the structure’s integrity and prevents long-term moisture exposure.

7. Monitor for Corrosion or Surface Wear

While aluminium is corrosion-resistant, environmental exposure over time can still cause minor surface degradation.

• Look for discolouration, pitting, or powdery residues on surfaces.
• If signs of corrosion appear, gently clean and consider applying a protective finish.

Periodic checks every six months help catch early signs of wear before they spread.

8. Avoid Pressure Washing

High-pressure cleaners may seem convenient, but they can damage the coating or force water into seals and mechanical areas.

• Stick to hand washing with a hose, sponge, and gentle detergent.
• Use low-pressure rinse techniques when cleaning nearby areas to avoid overspray.
• Safe cleaning methods protect surface coatings and prevent internal water ingress.
• Excessive pressure can also loosen fittings or dislodge tracks, leading to functional issues over time.

If deeper cleaning is needed, consider using a soft-bristle brush to gently remove dirt without harming the finish.

9. Keep Nearby Plants Trimmed

Plants growing too close to balcony shutters can cause scratching, build-up of organic matter, or unnecessary moisture exposure.

• Trim vines, shrubs, or balcony plants to avoid contact with the shutter surfaces.
• Clear any leaves or pollen that settle near hinges or tracks.
• Keeping nearby areas tidy helps preserve both appearance and function.
• Regular trimming also helps reduce the risk of insect activity, mould growth, and excess shade that can encourage moisture retention.

If you have potted plants on the balcony, ensure they’re positioned away from the shutter edges to allow proper airflow and avoid staining from runoff or soil splash.

10. Schedule Professional Maintenance Annually

While DIY care goes a long way, a professional inspection once a year offers reassurance. A qualified technician can assess mechanical integrity, check for signs of structural fatigue, and perform more detailed cleaning or realignment if required.

• Annual professional checks are especially useful for large installations or high-use areas.
• Maintenance of aluminium shutters regularly not only extends lifespan but also supports ongoing property value.

This approach is particularly relevant for property managers overseeing large-scale residential buildings on the Sunshine Coast.
