How to clean aluminium window frames: maintenance tips for long-lasting shine

If you’re wondering how to clean aluminium window frames, the good news is that it’s a relatively simple task.

Thankfully, you’ve chosen one of the lowest maintenance materials on the market, and one that is durable enough to last for around 45 years unscathed.

Keeping them in top shape doesn’t require a professional, just a few of the right tools and a little regular maintenance to remove loose dirt, water spots and stubborn stains whilst preserving the powder coating and overall finish.

From a gentle wipe-down with a damp cloth to using mild cleaning agents like soapy water, white vinegar, or even a cup of lemon juice, these simple steps will protect your aluminium frames and ensure they continue to perform beautifully.

How to clean aluminium window frames

Cleaning aluminium frames doesn’t need to be complicated. With the right approach, you can safely remove dirt, grime, and moisture buildup without harming the metal surfaces or affecting the powder coating. Here’s our easy guide to keeping your aluminium windows sparkling.

What you’ll need to get started

Before you begin, gather these cleaning supplies to achieve the best results. You don’t usually need all these items, but the more the merrier!

• Soft cloths or clean cloths
• Damp cloths
• Bucket of warm water or a mixture of water and mild detergent
• Drops of mild dish soap or mild soap
• Spray bottle
• Soft brush for window tracks and corners
• Lemon juice or a cup of white vinegar for stubborn stains
• Baking soda paste or soda paste for tough spots
• Fine steel wool (for oxidised areas only, sparingly)

The next steps that you’ll need to take

1. Remove loose dirt – Use a soft brush or dry cloth to sweep away dust and debris from aluminium surfaces and window tracks.
2. Prepare a gentle cleaning solution – Mix warm water with a few drops of mild dish soap, or combine equal parts water and white vinegar for a natural alternative.
3. Wipe frames carefully – Dampen a soft cloth in your solution and wipe all aluminium frames, paying attention to corners, edges, and window seals.
4. Tackle stubborn stains – For tough spots, create a soda paste by mixing baking soda with a small amount of water. Apply with a damp cloth, let it sit, then gently rub away. Avoid abrasive materials that could scratch the powder coating.
5. Rinse thoroughly – Use clean water to remove any soap or vinegar residues. This helps prevent white spots or water marks from forming.
6. Dry properly – Finish by drying frames with a soft, dry cloth. Ensuring aluminium surfaces are moisture-free reduces the risk of corrosion and keeps your windows looking fresh.

On how to maintain aluminium windows

Aluminium frames are exceptionally robust and designed to last decades, but regular maintenance ensures they remain in top condition.

Regular cleaning

• Wipe down frames every few months with a damp cloth to remove dust and prevent moisture buildup.
• Clean window tracks to avoid dirt accumulation, which can affect opening mechanisms.

Inspect for minor damage

• Check seals, hinges, and locking systems periodically. Minor repairs prevent larger issues.
• Lubricate moving parts with a light oil if needed.

Why aluminium is low maintenance

Aluminium is highly resistant to warping, rust, and rot, unlike timber. Powder-coated finishes retain their colour for years and require only a wipe-down to keep their shine. With basic care, your windows can achieve a life expectancy of 45–50 years, making them a long-lasting, reliable investment for your home.

Signs that aluminium windows may be coming to the end of their lifespan

While aluminium is durable, here are a few warning signs your windows may need attention:

• Persistent white spots or oxidised areas despite cleaning
• Warped or bent frames due to extreme impacts
• Window seals failing or condensation forming between panes
• Stiff or difficult-to-operate locking mechanisms
• Visible corrosion or pitting in exposed areas

How often should I clean aluminium windows?

Regular cleaning every 3–6 months is ideal, with more frequent wipe-downs in areas with poor air quality or heavy rainfall.

Yes. Aluminium’s strength-to-weight ratio is excellent; it doesn’t warp, and it remains secure and insulating even in cold temperatures.
