When it comes to cleaning aluminium, knowing the right methods makes all the difference. Aluminium bifold doors and windows are designed to look great and last for decades, but like any exterior feature, they benefit from a little care. A thoughtful cleaning routine not only keeps surfaces looking fresh but also supports the smooth operation of hinges, locks and tracks.
At Express Bi-Folding Doors, we take pride in the quality and finish of every aluminium system we manufacture and install. This guide brings together our expert advice on how to clean aluminium, maintain performance, and help your doors and windows stay at their best for years to come.
Aluminium is an exceptionally durable material that resists warping, swelling and cracking. Yet, like all metals, it can collect dirt, grime and residue from pollution or coastal air. Over time, this build-up can dull the finish and interfere with moving parts.
A regular cleaning routine keeps the surface looking sharp and ensures door and window components perform exactly as intended. Clean frames glide smoothly, seals remain tight, and the powder-coated finish continues to protect against corrosion and UV fading.
“A small amount of care goes a long way. Cleaning aluminium a few times a year keeps it looking beautiful and prevents minor issues from turning into costly repairs.”
— Steve Bromberg, Managing Director, Express Bi-Folding Doors
The best way to clean aluminium depends on what part of your system you are working on. Here is our expert-approved process for aluminium bifold doors:
Start by opening your aluminium bi-folding doors fully and clearing the tracks of any loose debris. Brush away dust, dirt, and leaves, then vacuum along the bottom rails. This prevents grit from scratching the aluminium while you clean.
Avoid harsh chemicals or household detergents such as washing-up liquid, which can strip the finish. Instead, use a mild, soapy mix made with warm water and a non-abrasive cloth. This is gentle enough to lift dirt without damaging the powder coating.
We recommend wiping in smooth, circular motions and rinsing with clean water to remove any residue. Dry the surface with a soft microfibre cloth for a streak-free result.
Tracks, hinges and rollers are key to keeping aluminium patio doors moving smoothly. After cleaning, apply a light silicone-based lubricant to hinges, handles, and locks. Avoid oil-based sprays like WD-40, which can attract dust or affect rubber seals. Regular lubrication not only ensures effortless movement but also helps prevent unnecessary wear on these essential components, extending the life of your doors.
For the glass panels, use a mix of half water and half white vinegar or a standard window cleaner. Spray onto a cloth rather than directly onto the glass to prevent streaks along the aluminium edges, and buff dry for a clear finish.
While cleaning aluminium frames, check the drainage holes and rubber gaskets. Make sure nothing blocks the outlets, as these help prevent water build-up. If you spot any damage, contact a professional for guidance. Here at Express, we offer a comprehensive 10-year guarantee on all our products, and we boast a dedicated after-sales team to assist with even the slightest issue or concern about your installation.
Homes located near the sea or in busy urban environments require a little extra care. Salt-laden air and pollution can settle on aluminium surfaces, gradually eroding protective coatings if not cleaned regularly.
If you live right on the waterfront, aim to clean exterior aluminium at least once a month, and rinse with fresh water after strong winds to remove any salt residue. For homes in coastal areas but set back from the beach, cleaning every three months is usually sufficient to prevent the build-up of traffic film and grime on doors and windows.
In urban settings, air pollution, vehicle emissions, and dust can have a similar effect over time. Regular quarterly cleaning helps to maintain the appearance of aluminium surfaces and prevent dulling or staining caused by airborne contaminants. In areas with heavy traffic or industrial activity, more frequent cleaning, every one to two months, may be necessary to preserve the finish.
While cleaning aluminium is straightforward, there are a few common errors that can shorten the lifespan of your system:
By avoiding these mistakes, you protect both the look and performance of your aluminium doors and windows.
Cleaning aluminium is simple, quick and highly effective. Regular care not only protects the finish but also keeps doors and windows performing as they were designed to. Whether you have aluminium bifold doors, sliding doors, or aluminium window frames, a thoughtful cleaning routine makes a lasting difference.
