Keeping your aluminium windows in immaculate condition isn’t just about aesthetics – it’s important for maintaining longevity and energy efficiency. Without regular maintenance, dirt and grime can corrode the frames over time, potentially compromising their structural integrity and weatherproofing capabilities. This deterioration can lead to draughts, increased energy bills, costly repairs, or even premature replacement.
As experts in double glazing with over 60 years of experience, we’ve put together this comprehensive guide on how to clean aluminium windows effectively.
Essential Cleaning Materials
Before starting the cleaning process, gather these items:
- Warm soapy water
- Mild detergent (such as washing-up liquid)
- A soft, microfibre cloth or sponge
- Glass spray cleaner
- White vinegar
- Clean water for rinsing
- Soft brush
- Aluminium polish (optional)
- Anti-mould solution (if needed)
Avoiding Harsh Cleaning Products
It’s a good idea to avoid harsh cleaning products as these can damage metal surfaces. Always test any cleaning solution on a small, inconspicuous area first and wait 24 hours to ensure no adverse reactions occur.
Cleaning Guide
Initial Preparation
Start by removing loose dirt from the aluminium window frames using a soft brush. Pay close attention to corners and crevices where dirt tends to accumulate. This preliminary step is crucial as it prevents scratching during the main cleaning process.
The Main Clean
-
- Mix warm water with a mild detergent
- Using a soft sponge or damp cloth, clean the aluminium frame in a circular motion
- Give particular attention to frame joints and hinges
- For stubborn stains, create a solution using white vinegar and water (1:1 ratio)
- Clean glass panes with an appropriate glass spray
- For tough stains that persist, try leaving the cleaning solution on for a few minutes before wiping
- Give the windows a good rinse so as not to leave any cleaning solution or chemicals on the windows
Dealing with Specific Issues
Removing Oxidation
Oxidation is a natural chemical reaction that occurs when aluminium is exposed to air and moisture over time, similar to how iron rusts. This process can leave your window frames looking dull, chalky, or whitish in appearance and, if left untreated, can gradually weaken the surface of the aluminium. If your aluminium window frames have become dull or chalky:
- Create a solution of equal parts water and white vinegar
- Apply with a soft cloth using circular motions
- For tough oxidation, use a specialised aluminium cleaner
- Rinse thoroughly and dry immediately
Polishing Frames
Even with regular cleaning, aluminium frames can lose lustre over time due to environmental exposure and general wear. Polishing restores the original shine and helps protect the surface against future oxidation and weathering. To restore shine:
- Apply a polish specifically designed for aluminium using a fresh microfibre cloth
- Buff gently in circular motions
- Avoid over-polishing to protect the surface coating
- Give a good rinse after polishing
Treating Mould and Mildew
Mould and mildew are common issues for windows in humid or poorly ventilated areas, particularly around bathroom windows or in properties near the coast. These fungi not only look unsightly but can also pose health risks and, if left untreated, may damage window seals and gaskets over time. To treat this:
- Mix water with a specialised anti-mould solution
- Apply carefully using a soft brush
- Pay close attention to seals and joints
- Ensure thorough drying to prevent regrowth
Cleaning Hard-to-Reach Windows
Safety should always be your primary concern when cleaning high windows. Never overreach or use unstable ladders, and if windows are high or difficult to access, consider hiring a professional window cleaner. However, for windows that are just safe to clean, you can:
- Use telescopic poles with microfibre attachments
- Pre-moisten the cleaning attachments with your cleaning solution
- Work methodically from top to bottom
- Ensure proper drying to avoid water spots
Common Mistakes to Avoid
When cleaning aluminium windows, here are the most common mistakes to avoid:
- Using abrasive cleaning materials that can scratch metal surfaces
- Cleaning in direct sunlight, which causes premature drying and streaking
- Neglecting regular maintenance, leading to stubborn stains
- Using harsh cleaning products that damage protective coatings
- Forgetting to dry thoroughly, especially around door frames
