Aluminum doors are an ideal choice for both homes and businesses due to their strength, durability and modern aesthetics. However, to keep them in perfect condition, it’s important to perform proper maintenance and avoid the accumulation of dirt, stains or corrosion.
Here are 8 steps to effectively clean and protect your aluminum door, ensuring it looks impeccable and prolonging its lifespan.
Why is it Important to Clean Our Aluminum Doors?
Aluminum doors are designed to last for many years, but their constant exposure to external agents such as dust, moisture, grease and contamination can deteriorate them over time.
Maintaining a cleaning routine not only contributes to the aesthetics of the home or business, but also brings the following benefits:
Greater durability: Regular cleaning prevents the accumulation of dirt and debris that can generate corrosion or wear on aluminum.
✅ Prevents rust and corrosion: Although aluminum is a tough material, lack of maintenance can lead to staining or corrosion in humid climates.
✅ Improve appearance: Clean, shiny doors make any space look more modern and cared for.
✅ Improved functionality: Dust and dirt-free frames and hinges allow the door to function properly without obstructions.
✅ Hygiene and safety: Keeping doors clean prevents the accumulation of bacteria and germs, especially in high-traffic areas.
Now that we know the importance of maintenance, let’s continue with the steps to properly clean and protect our aluminum doors.
8 Steps to Clean & Protect Your Aluminum Doors
Aluminum is one of the most widely used building materials because it is cheap, strong and stylish. But this does not mean that they don’t have to be cared for, as we have already mentioned.
Here are some steps, tips and tricks to keep them clean. Of course, it all depends on your product, so we suggest you ask your installer for specific care, since bifolds may need more than products with glass, for example.
1. Remove Dust & Loose Dirt
Before applying any cleaning solution, remove dust and dirt to prevent scratches.
- Use a dry cloth or vacuum cleaner with a brush attachment to remove dust.
- For exterior doors, rinse the surface with a garden hose or a bucket of water.
- For interior doors, wipe with a damp microfiber cloth to lift dirt without scratching.
💡 Tip: Avoid using wire brushes or abrasive sponges, as they can scratch the aluminum surface.
2. Wash the Frames with Mild Soap & Water
To clean aluminum without damaging its finish:
- Mix warm water with a few drops of mild dish soap.
- Use a soft sponge or microfiber cloth to gently wipe the door.
- Pay extra attention to corners and edges where dirt accumulates.
- Use a soft-bristle brush for stubborn spots.
- Rinse with clean water to remove any soap residue.
- This method keeps aluminum looking pristine without causing wear or fading.

3. Remove Grease & Stubborn Stains
If your aluminum door has grease spots or stubborn dirt, try this natural cleaning method:
- Mix ¼ cup of baking soda with ½ cup of lemon juice to create a paste.
- Apply the paste to the stains using a sponge and let it sit for 5-10 minutes.
- Gently scrub with a cloth and rinse with clean water.
🍋 Bonus: This mixture not only cleans but also restores aluminum’s natural shine.
4. Rinse the Frames &Glass Panels Thoroughly
After applying cleaning products, it’s important to rinse off any residue:
✔ Use a hose for exterior doors or a damp cloth for interior doors.
✔ Repeat rinsing until all cleaning solutions are removed.
✔ Dry with a clean microfiber cloth to prevent water spots.
💡 Tip: If your aluminum door has glass panels, use a streak-free glass cleaner for a crystal-clear finish.
5. Clean Interior Aluminum Frames
Interior aluminum doors require a slightly different approach since they don’t face exterior weather conditions:
- Wipe down the surface with a damp cloth to remove dust.
- Apply a mild soap solution with a sponge.
- Use a soft-bristle brush for tight corners and grooves.
- Dry thoroughly to prevent moisture buildup.
This method ensures that sliding doors and other interior aluminum frames remain free of dust and grime.
6. Use a Specialized Cleaner for Heavy Dirt
If grime persists, a commercial aluminum cleaner may be necessary:
✅ Choose a biodegradable, non-toxic cleaner to avoid harsh chemicals.
✅ Follow the manufacturer’s instructions carefully.
✅ Wear gloves and ensure proper ventilation when using chemical cleaners.
💡 Tip: Always test the cleaner on a small, hidden section first to check for compatibility with your aluminum finish.
7. Dry the Door to Prevent Water Damage
Once the cleaning is complete, drying is essential to avoid water stains and oxidation:
- Use a dry microfiber cloth to absorb excess moisture.
- For exterior doors, let them air dry in the sun.
- Avoid using hot air dryers, as they can damage the aluminum coating.
💡 Tip: Proper drying also prevents mold and mildew from forming in humid areas.

Polish & Protect the Aluminum Finish
For a long-lasting shine and extra protection:
✅ Use fine steel wool with a bit of water for a polished look.
✅ Apply a specialized aluminum polish or wax to protect against dirt and moisture buildup.
✅ If there’s any oxidation, use a rust remover suitable for aluminum, testing it on a small area first.
This step helps maintain the aluminum’s sleek, modern appearance while adding an extra layer of protection.
