Aluminum frames look sleek and shiny at first, but over time the aluminum can oxidize. The result: dull window and door frames with white spots and specks. Learning how to clean corroded aluminum is a fast and easy way to brighten up aluminum framing. The processes of how to clean aluminum door and window frames is similar to how to clean cast aluminum cookware and automotive parts, so if you’ve done that before it’ll be easy to pick up!

Unfortunately most fabricators fabricate their products after painting leaving uncoated surfaces exposed to the elements which promotes corrosion but Nu-lite Balustrading fabricate and weld all their Balustrade products before powder coating so that all surfaces are coated therefore eliminating corrosion from their aluminium products.

Best Way to Remove Corrosion From Aluminium Frames

Depending on the extent of the corrosion, you can use a variety of different aluminum cleaner options. Aluminum corrosion removal with vinegar is one homemade cleaner option made from equal parts water and white vinegar. You can use a range of different diluted acids to remove corrosion.

You can use a steel wire brush or steel wool to polish the aluminum frames after cleaning if you don’t mind some surface scratching. Some aluminum materials may be more scratch-resistant than others, such as glass cafe screens with powder-coated aluminum and stainless steel frames.

If a homemade aluminum cleaner with acid or detergent doesn’t seem to cut it, you may want to use a commercial aluminum cleaner. These products use various chemicals and enzymes to remove the corrosion and may be more efficient if you have a lot of aluminum to clean! In general, aluminum responds well to gentle cleaners combined with abrasive scrubbing.

Clean Anodised Aluminium Window Frames

Anodised aluminum features a bonded coating of aluminum oxide that adds durability, a deeper metallic look, and UV-resistance. The best way to clean anodised aluminum window frames involves preserving the anodised surface, so that means no harsh cleaners or chemical solutions.

To clean anodised aluminum frames without removing the anodisation, wipe the frames down with a damp sponge. With diluted mild detergent, scrub the frames with an abrasive sponge. Rinse and dry thoroughly to avoid water spots. To handle exterior aluminum framing, you can use a power washer if more convenient.
