How to Clean Aluminium Outdoor Furniture: The Ultimate Guide

Aluminium outdoor furniture is a stylish and practical choice for Australian homes. It’s lightweight, durable, and rust-resistant, making it perfect for patios, decks, and garden spaces. But even though it’s low-maintenance, it still requires the right care to stay looking its best. Whether you own an elegant aluminium outdoor dining set or a sleek aluminium outdoor lounge from Bay Gallery, this guide will walk you through everything you need to know to clean and maintain your furniture properly.

Why Aluminium Outdoor Furniture Needs Special Care

Aluminium doesn’t rust like other metals, but it can oxidise over time. This oxidation appears as a chalky white residue, especially in coastal regions or high-sun areas. Regular cleaning helps remove dirt, prevent staining, and reduce the effects of UV and salt exposure. With simple upkeep, your outdoor furniture can retain its original finish for years.

Supplies You’ll Need for Cleaning Aluminium Furniture

Gather Your Cleaning Materials:

  • Bucket

  • Warm water

  • Mild dishwashing liquid (pH-neutral)

  • Soft-bristle brush or non-abrasive sponge

  • Microfibre cloths or soft towels

  • White vinegar (for stubborn stains)

  • Baking soda (for oxidation)

  • Car wax with UV protection (optional, for ongoing care)

  • Garden hose

Prepare the Area: Choose a shaded, well-ventilated area to prevent quick drying that could leave soap spots. Lay down a towel or tarp to protect your flooring and catch excess water.

Step-by-Step: How to Clean Aluminium Outdoor Furniture

1. Remove Loose Dirt and Debris

Brush or hose off dust, leaves, and debris. Use a soft cloth or brush to avoid scratching the surface, especially if your furniture has a powder-coated finish.

2. Wash with Mild Soap Solution

Mix a few drops of mild detergent with warm water in your bucket. Using a soft sponge, gently scrub the surfaces, focusing on joints and corners where grime tends to build up.

3. Tackle Stubborn Grime or Stains

For tougher spots like bird droppings or tree sap, dip a brush or cloth into the soapy solution and gently scrub. For mildew or scuff marks, use a 50/50 mix of white vinegar and water. Let it sit for a minute before wiping away.

4. Rinse Thoroughly

Use a garden hose on a gentle setting to rinse away all soap and residue. Leftover detergent can leave a cloudy film if not washed off completely.

5. Dry Properly

Use a soft towel or microfibre cloth to dry your furniture thoroughly. This prevents water spots and helps you check that all grime and residue are gone.

Removing Oxidation (Chalky White Residue) from Aluminium

Oxidation is a natural reaction between aluminium and oxygen. It’s more common in coastal areas or after extended sun exposure.

  • How to Remove Light Oxidation: Make a paste with baking soda and water. Gently rub it onto the affected area using a soft cloth in circular motions. Rinse and dry. For a more polished finish, consider using a specialised aluminium cleaner or polish.

  • Preventing Future Oxidation: Once clean and dry, apply a thin layer of car wax with UV protection. This fills in micro-pores and creates a protective barrier that shields against sun, salt, and moisture.

Tips for Stubborn Stains and Marks

  • Rust on Hardware: While the aluminium itself doesn’t rust, steel bolts or screws can. Remove surface rust with white vinegar and apply a rust inhibitor if needed.

  • Tree Sap or Grease: Use mild soapy water first. For sticky spots, try a dab of baking soda on a damp cloth. Avoid harsh solvents like acetone, which can damage the powder coating.

  • Water Spots: White rings from mineral deposits can be gently wiped away with vinegar, then rinsed. For extra-tough marks, lemon juice can help but should be used sparingly and rinsed thoroughly.

Protecting and Maintaining Aluminium Furniture

✅ Routine Cleaning: Wipe down your furniture every few weeks. If you live near the coast or under trees, consider cleaning more frequently to prevent salt or sap buildup.

✅ Use Protective Covers: Bay Gallery’s furniture covers are ideal for protecting your pieces from UV rays, rain, and debris. Always ensure the furniture is clean and dry before covering.

✅ Position and Prevention: Place your furniture in semi-shaded areas to reduce direct sun exposure. Use shade umbrellas or sails, and avoid placing furniture directly on soil or grass.

✅ Avoiding Scratches: Lift your furniture when moving it; don’t drag. Use felt pads on chair legs and placemats or coasters on tabletops to protect from scratches or heat marks.

✅ Seasonal Deep Clean & Wax: Give your furniture a thorough clean at least once a season. After drying, reapply car wax for added protection and shine.
