How to Clean Aluminium Windows and Doors

Apart from their sleek and stylish appearance, aluminium windows and doors are popular because of their low maintenance requirements. However, over time, airborne dust, car exhaust and even the occasional bird or insect can leave your aluminium frames looking less than pristine. Regular cleaning is essential to ensure they continue to look their best and function properly for many years to come.
On the bright side, aluminium, especially when powder-coated, is exceptionally easy to clean. The powder coating provides a protective layer that prevents corrosion and minimises the risk of scratches and abrasions. This not only enhances the appearance of the aluminium but also makes cleaning hassle-free.
Let’s explore the key steps and best practices for keeping your aluminium frames looking as good as new.
Step-By-Step Guide to Cleaning Aluminium Frames Effectively
Cleaning your windows and doors is a relatively straightforward task, but it’s important to follow the right steps to avoid damaging your frames and surfaces. Here are our five essential steps to keep your aluminium frames in great condition:
- Remove Dirt and Debris – Before you start cleaning, clear away any dust, dirt or cobwebs. Use a soft duster, vacuum cleaner or hosepipe to avoid scratching the glass or frames. Pay extra attention to corners and crevices where dirt tends to accumulate.
- Prepare Soapy Water – There’s no need to spend money on specialist cleaning products. Warm, soapy water works perfectly for cleaning aluminium frames. Simply fill a clean bucket with warm water and add a small amount of washing-up liquid.
- Wash the Frames – Dip a soft sponge or microfiber cloth into the soapy water and gently wash the frames both inside and out. Make sure to clean every part, including corners and edges, to remove all dirt and grime.
- Rinse Thoroughly – After washing, rinse the frames thoroughly to remove any soapy residue and prevent streaks. Use a clean cloth soaked in fresh water to wipe down the frames, or use a hosepipe for exterior frames.
- Dry Completely – To prevent watermarks and moisture build-up, dry the frames thoroughly with a soft or microfiber cloth. Pay special attention to corners, crevices, hinges and tracks where moisture can collect.
Do’s and Don’ts for Cleaning Aluminium Windows and Doors
Do’s:
Use Soft Cleaning Tools
- Opt for soft sponges, microfiber cloths or soft-bristled brushes to clean your aluminium frames. These tools are gentle and help avoid scratching the surface, preserving the finish of your frames.
Clean Regularly
- Perform regular gentle cleaning instead of waiting for heavy soil build-up. Frequent upkeep maintains the appearance and functionality of your windows and doors with minimal effort.
Start at the Top
- Begin cleaning from the highest point and work your way down. This method prevents dirt and debris from falling onto areas you’ve already cleaned, making the process more efficient and thorough.
Address Hard-to-Reach Areas
- Remember to clean areas that are hard to reach or hidden when the window or door is closed. Dirt build-up in these spots can jam the mechanisms and affect overall performance.
Don’ts:
Use Abrasive Cleaners or Tools
- Avoid harsh chemicals, abrasive pads or steel wool, as these can scratch or damage the powder coating on your aluminium frames.
Use High-Pressure Washers
- Refrain from using high-pressure washers, which can force water into seals and joints, causing potential damage to the frames and mechanisms.
Ignore Manufacturer’s Guidelines
- Don’t disregard the manufacturer’s cleaning and maintenance instructions. Following these guidelines ensures you don’t void warranties or unintentionally damage your frames.
Allow Water to Pool
- Don’t leave water standing on the frames or in the tracks after cleaning. Ensure all moisture is removed to prevent watermarks and potential damage.
How Often Should Aluminium Doors and Windows be Cleaned?

To keep your aluminium doors and windows at their best, clean the glass monthly and the frames at least once every three to four months. Regular cleaning helps prevent the build-up of dirt and grime, making maintenance easier and extending the life of your frames.
However, the frequency might vary between windows and doors. Doors, especially patio doors like bi-folding, sliding or French doors, may need more frequent attention. Since these doors are used more often, are larger and heavier, and have more complex components than windows, they tend to accumulate dirt and show wear more quickly.
If you notice your doors or windows looking a bit worse for wear or not functioning as smoothly, it’s a good idea to clean them more often. Addressing visible dirt or issues promptly will help maintain their appearance and performance.
How to Clean Unpainted Aluminium Frames
Unpainted or non-powder coated aluminium frames, often found in older homes or certain commercial settings, lack the protective layer that coated frames have. This makes them more susceptible to environmental damage and requires a slightly different cleaning approach:
- Check for Damage– Look for signs of oxidation or corrosion, which appear as white, powdery deposits. Unpainted aluminium can attract more grime and show wear more easily. During your cleaning, also check for any leaks, holes or other signs of structural damage that might need attention.
- Clean with Soapy Water – Use warm, soapy water and a soft cloth to remove surface dirt. For stubborn grime or corrosion, gently scrub with a soft-bristled brush to avoid scratching the aluminium.
- Dry Thoroughly – Dry the frames completely with a soft, clean cloth to prevent water spots and ensure a polished finish.
- Treat Corrosion – If you find corrosion, clean it with a specialised aluminium cleaner or a baking soda and water solution. For severe corrosion or extensive damage, consult with a specialist from Majestic Designs, who can advise on repair, restoration or replacement.
- Increase Cleaning Frequency – Since unpainted aluminium is more prone to environmental damage, clean the frames more often to maintain their appearance and prevent long-term issues. For frames with unfixable damage, consider replacement.
