How to Maintain Your Aluminium Windows

Aluminium windows are a popular choice for Perth homes because they are strong, modern, low maintenance, and well suited to Australian conditions. But while aluminium is known for being durable, it still needs the right care to keep it looking good and working properly over time.

Like any part of your home, your windows are exposed to weather, dust, moisture, salt air, and everyday use. Over time, these factors can affect the appearance and function of your windows if they are not maintained properly.

The good news is that maintaining aluminium windows is simple when you know what to look for. With regular cleaning, basic inspections, and a little attention to moving parts, you can help extend the lifespan of your windows and keep them performing as they should.

We have been installing aluminium windows and doors for Perth homes for over 20 years. Here are our practical tips for keeping your aluminium windows in great condition for years to come.

Why Aluminium Window Maintenance Matters

Aluminium windows are designed to be long lasting, but maintenance still plays an important role in protecting your investment.

Regular care helps prevent dirt, grime, salt, and debris from building around the frames, glass, tracks, seals, and moving components. This is especially important in Perth homes located near the coast, where salt in the air can speed up wear on exposed materials.

A simple maintenance routine can help your windows open and close smoothly, protect the finish of the aluminium, reduce the chance of damage, and keep your home looking well cared for.

As a general maintenance guide, we recommend washing external aluminium window and door frames with clean water, a mild non-abrasive detergent, and a soft sponge, followed by a fresh water rinse. We also recommends more frequent cleaning in coastal or industrial areas due to increased exposure.

Why Coastal Homes Need Extra Window Maintenance

If you live close to the ocean, your aluminium windows may need a little more attention than windows in inland suburbs. Salt air can settle on frames, tracks, and hardware, which may lead to build-up over time if it is not rinsed away regularly.

This does not mean aluminium is a poor choice for coastal homes. In fact, aluminium is still a durable and practical option. It simply means regular cleaning becomes even more important. A quick rinse with fresh water can help remove salt residue and protect the finish, especially on windows that are directly exposed to wind and weather.

Clean Your Windows Regularly

The best place to start is regular cleaning.

Aluminium windows do not need harsh products or complicated treatments. In most cases, mild detergent mixed with water and a soft cloth is enough to clean both the frames and glass. Once you have cleaned the surface, rinse everything thoroughly with fresh water to remove any soap residue and help prevent streaks or water spots.

Cleaning your windows regularly helps stop dirt and grime from building up and becoming harder to remove later. It also helps protect the aluminium finish from staining, particularly if your windows are exposed to rain, wind, dust, or salt air.

For homes close to the ocean, more frequent cleaning is usually recommended. Salt can settle on frames and hardware over time, so rinsing with fresh water helps reduce build-up and protect the window's components.

If you are cleaning glass, a microfibre cloth or squeegee can help reduce streaks and leave a clearer finish. For aluminium frames, avoid anything abrasive that could scratch or dull the surface.

Inspect Weatherstripping and Seals

Weatherstripping plays an important role in how well your windows perform.

It helps seal gaps around the window, reducing drafts, dust, noise, and unwanted heat transfer. When weatherstripping becomes worn, cracked, loose, or damaged, your windows may stop insulating your home properly. This can affect comfort inside the home, particularly during Perth’s hotter months when keeping cool air inside is important.

The Australian Government’s YourHome guide to glazing explains that glazing needs to work alongside orientation, insulation, shading, and weather sealing to support good thermal performance in the home.

Because of this, it is worth checking the seals around your aluminium windows every few months. Look for signs of wear, gaps, cracking, or debris that may prevent the window from closing properly.

If the weatherstripping is badly damaged, replacement may be needed to restore the window’s performance.

Lubricate Moving Parts When Needed

Most aluminium windows include moving parts such as handles, hinges, locks, rollers, and sliding mechanisms. These components need to move smoothly for the window to operate properly.

Over time, dust, sand, and salt can build up around these areas, especially in sliding windows or homes near the coast. If your windows start to feel stiff, noisy, or harder to open and close, lubrication may help.

A silicone-based lubricant is usually the best option for aluminium window hardware because it helps reduce friction without attracting as much dirt as some oil-based products. Apply it sparingly to the relevant moving parts and avoid overusing it, as too much product can collect dust.

Before lubricating, make sure the area is clean. Applying lubricant over dirt or grit can make the problem worse and may affect the smooth operation of the window.

If lubrication does not improve the issue, the window may need professional inspection.

Avoid Harsh Chemicals and Abrasive Products

One of the easiest ways to damage aluminium windows is by using the wrong cleaning products.

Strong chemicals, abrasive pads, steel wool, and harsh cleaners can damage the aluminium finish and may also affect the glass. This can leave marks, scratches, or dull patches that are difficult to repair.

Instead, stick to gentle cleaning methods that protect the surface while still removing dirt effectively.

What to Avoid When Cleaning Aluminium Windows

As a general guide, avoid bleach, abrasive powders, solvent-based cleaners, metal scrapers, and rough scourers. These products can damage the surface of the aluminium, scratch the glass, or wear down protective finishes.

Mild detergent, clean water, soft cloths, microfibre towels, and non-abrasive sponges are usually all you need for routine cleaning. If you are unsure whether a product is safe, test it on a small, discreet area first or ask your installer for advice.

Check Your Windows Regularly for Wear and Tear

Regular inspections help you catch small issues before they become bigger problems.

You do not need to do anything complicated. Every few months, take a quick look at your windows and pay attention to how they feel when you open, close, and lock them.

A simple inspection should include:

Checking that windows open and close smoothly

Looking for dirt or debris in tracks

Inspecting seals and weatherstripping for damage

Testing locks, handles, and latches

Checking for water marks, corrosion, or staining

Making sure drainage holes are clear

Looking for cracks or damage in the glass

This small habit can help you identify whether your windows need cleaning, lubrication, minor maintenance, or professional attention.

It is much easier to deal with early signs of wear than to wait until a window becomes difficult to use or no longer seals properly.

Know When Maintenance Is Not Enough

In many cases, regular maintenance will keep aluminium windows looking and working beautifully for years. However, there may be a time when cleaning and lubrication are no longer enough.

If your windows are heavily damaged, difficult to operate, no longer secure, or showing signs of significant wear, replacement may be the better long-term option.

This is especially true if your windows are older and are affecting your home’s comfort, energy efficiency, or appearance.
