This aluminium decking care guide explains everything you need to know to keep your deck looking its best, including cleaning tips, seasonal maintenance and best practices to ensure optimal performance year-round.

Why Aluminium Decking Is So Low Maintenance

Unlike timber or composite alternatives, aluminium decking requires extremely low levels of maintenance.

It’s naturally resistant to:

  • Rust and corrosion (especially when powder-coated or anodised)

  • Moisture, frost and UV exposure

  • Mould, algae and insect damage

  • Warping or splintering

Because of its non-porous surface, aluminium decking doesn’t absorb water or require sealing, staining or painting, making it ideal for commercial environments where reliability and safety are paramount.

Routine Cleaning: Keeping Your Aluminium Deck Looking New

Regular cleaning not only keeps your decking looking pristine but also helps maintain slip resistance and prevent surface buildup.

Routine Sweeping

  • Sweep the surface regularly with a soft-bristle broom to remove leaves, dust and grit.

  • This prevents organic matter from collecting in drainage channels or joints.

General Cleaning

  • Mix warm water and a mild pH-neutral detergent (such as washing-up liquid).

  • Use a soft sponge, mop or soft brush to loosen dirt.

  • Rinse thoroughly with clean water to avoid leaving soap residues.

Avoid:

  • Abrasive pads or steel brushes that could scratch the coating.

  • Strong alkaline or acidic cleaners not formulated for aluminium.

Seasonal Maintenance

Although aluminium decking is built for longevity, a simple seasonal check helps ensure continued performance.

Spring

  • Remove any winter debris from drainage channels or soffit systems.

  • Wash down surfaces to refresh the appearance.

Summer

  • Clean regularly to prevent dust and pollen accumulation.

  • Check for any signs of water pooling (should be minimal with correct fall).

Autumn

  • Sweep regularly to remove leaves and organic debris.

  • Inspect drainage outlets and remove blockages.

Winter

Aluminium is frost- and snow-resistant, but you can:

  • Remove snow with a plastic shovel or soft brush (avoid metal edges).

  • Use warm water to melt ice if needed, never use rock salt or harsh de-icers.

    Check that surface drainage channels remain clear.

Maintaining the Coating and Finish

Most aluminium decking systems are finished with a powder coating or anodised surface for added corrosion and UV protection.

To keep the finish looking its best:

  • Clean coatings gently, avoid harsh chemicals or high-pressure blasting.

  • Touch up minor surface scratches with an aluminium paint pen.

  • Never sand or polish coated aluminium, as this may damage the protective layer.
