Coastal Care: Protecting Your Outdoor Blinds and Awnings from Salt Air

The Realities of Coastal Living

Living near the ocean on the Sunshine Coast is a lifestyle dream, offering beautiful beaches and fresh sea breezes. However, it also creates one of the most punishing environments in Australia for external building materials and outdoor fixtures.

At Kawana Blinds, we specifically use high-grade aluminium, stainless steel components where necessary, and premium powder-coating to ensure our awnings survive in coastal environments. But even the best materials require a little bit of help from homeowners to achieve their maximum lifespan.

The Impact of Salt Air

Sea salt is highly corrosive and can be carried kilometres inland by coastal breezes. When microscopic salt crystals settle on your awning tracks, bottom bars, and fabrics, they attract and hold moisture. Over time, this salty moisture breaks down protective powder coatings, causes oxidation on aluminium, and degrades fabric fibres.

Cleaning Frequency Guidelines

• Beachfront properties (Mooloolaba, Sunshine Beach, Caloundra, Moffat Beach): Wash fabrics and wipe tracks with fresh water every 2-4 weeks.
• Coastal suburbs (Maroochydore, Twin Waters, Noosaville): A good hose down and clean every 4-6 weeks.
• Inland suburbs (Buderim, Nambour, Maleny): A thorough clean every 3-4 months is generally sufficient.

How to Wash Your Awning Fabrics

Never use high-pressure washers, as they can damage the fabric weave and strip protective coatings right off the material. Likewise, avoid harsh scrubbing brushes and heavy detergents.

Instead, gently hose the blinds with fresh water to remove loose salt and dust. Then, use a soft cloth or a very soft bristle brush with a mild, soapy water solution to wipe away stubborn dirt. Rinse thoroughly with the hose immediately afterwards.

Maintaining Tracks and Hardware

The smooth operation of your blinds depends heavily on the tracks staying clean and lubricated. Wipe the inside of the aluminium side channels with a damp cloth to remove grit and salt buildup.

Moisture Management and Mildew Prevention

The humid Queensland climate is perfect for mildew growth. While premium awning fabrics like Vistaweave and Dickson Acrylic are treated with anti-microbial coatings, mould can still grow on the dirt and organic matter that sits on top of the fabric.

Ensure your blinds are fully extended and completely dry after a rainstorm before you retract them. Rolling up a wet awning into a dark headbox is a guaranteed recipe for mould.

Regular Hardware Inspections

Take a few minutes each season to inspect the mounting brackets, crank handles, and bottom bar locks. If you notice any superficial rust or oxidation, a quick clean and a light spray of silicone will stop it in its tracks, protecting your investment for years to come.
