How to Clean Aluminium Window Frames: A Step-by-Step Guide

Aluminium window frames are sleek, durable, and low-maintenance – but they still need regular cleaning to stay looking their best.

Over time, dirt, grime, and even signs of oxidation can build up, especially in Melbourne’s mix of urban pollutants and unpredictable weather.

In this guide, we’ll show you how to clean your aluminium window frames safely and effectively, using both household products and professional methods.

What You'll Need to Clean Aluminium Window Frames

Soft microfiber cloths
Mild dish soap
White vinegar
Baking soda
Lemon juice
Warm water
Bucket or spray bottle
Soft toothbrush or nylon detail brush
Protective gloves

Before You Start: A Few Tips

Avoid cleaning during hot sunny days – rapid drying can cause streaks.
Always test any cleaning solution on a small, hidden section first.
Use separate cloths for frames and glass to avoid cross-contamination.

Cleaning Aluminium Window Frames
(Outside)

Step 1: Rinse Off Loose Dirt

Use a hose or a bucket of water to rinse the frames thoroughly. This helps loosen surface grime and makes the rest of the cleaning more effective.

Step 2: Wash With Soapy Water

Mix warm water with a few drops of mild dish soap. Dip a cloth or sponge in the solution and gently scrub the frames. For corners and tight spots, use a soft toothbrush or nylon brush.

Step 3: Tackle Corrosion with Baking Soda and Lemon Juice

To remove signs of oxidation or light corrosion, mix one part baking soda with two parts lemon juice into a paste. Apply it to the affected areas, let it sit for 10–15 minutes, then scrub gently with a soft brush. Rinse thoroughly with clean water.

Step 4: Dry Thoroughly

Use a clean, dry cloth to wipe down the frames. This prevents water spots and ensures a streak-free finish.

Cleaning Aluminium Window Frames
(Inside)

Step 1: Wipe Down With Damp Cloth

Using a damp cloth or sponge, wipe the inside frames to remove surface dust. Pay attention to corners and joints.

Step 2: Apply Soapy Water or Natural Cleaner

As with the exterior, use a mild soap solution or vinegar-water mix for internal cleaning. Avoid spraying directly on the frames – instead, apply to your cloth.

Step 3: Detail the Crevices

Use a toothbrush or detail brush to clean any buildup in creases and joints.

Step 4: Dry the Surface

Finish by drying with a clean microfiber cloth.

Dealing With Stubborn Stains or Neglected Frames

If you’re dealing with long-term grime or oxidation:

A vinegar soak or repeated baking soda paste application may help.
Avoid steel wool unless absolutely necessary – it can scratch the surface.
For difficult cases, consider calling in the pros.

Keep Them Looking Their Best

Clean frames every 6 months (more often in coastal or high-pollution areas).
Trim back nearby plants or trees that contribute dust or sap.
Apply a protective wax or aluminium-safe sealant annually if desired.
