The team at Simmal understands how important it is to keep aluminium looking its best. Aluminium's combination of strength, lightweight properties, and corrosion resistance makes it an ideal choice for a selection of uses, from household items to light industrial applications. However, over time, aluminium can accumulate dirt, oxidation, and stains, which may dull its appearance.

Whether you’re maintaining aluminium in your home, workshop, or small business, proper cleaning is essential to preserve its appearance and functionality. This article provides practical tips for cleaning and maintaining aluminium effectively and safely.

Understanding Aluminium and Its Properties

Before we begin discussing the cleaning process, it’s important to understand why aluminium requires specific care. Aluminium naturally forms a thin oxide layer on its surface, protecting it from corrosion. However, this layer can sometimes appear dull or develop stubborn stains. Therefore, cleaning aluminium requires a gentle approach to preserve this protective layer while removing dirt and grime.

Supplies You’ll Need

To effectively clean aluminium, make sure you have the following supplies:

  • Warm water
  • Mild dish soap or detergent
  • Soft cloths or sponges
  • Non-abrasive scrub pads
  • Baking soda (optional for tougher stains)
  • White vinegar or lemon juice
  • Aluminium polish or a suitable wax (for extra shine)

Avoid harsh chemicals, abrasive materials, or steel wool, as these can scratch or damage the surface.

Step-by-Step Cleaning Process

1. Prepare the Surface

Begin by removing any loose dirt, dust, or debris from the surface of the aluminium using a dry, soft cloth or brush. This prevents scratching when you apply cleaning agents.

2. Wash with Soap and Water

Mix a few drops of mild dish soap into warm water. Dampen a soft cloth or sponge in the solution and gently scrub the aluminium surface. Pay extra attention to areas with visible stains or grime. Rinse thoroughly with clean water to remove soap residue.

3. Remove Oxidation

For tougher stains and oxidation:

White Vinegar Solution: Mix equal parts white vinegar and water. Apply the solution to the aluminium surface using a cloth or sponge. Let it sit for 5-10 minutes, then gently scrub.

Lemon Juice and Baking Soda: Sprinkle baking soda over the surface, then add a few drops of lemon juice. The mixture will fizz, helping to lift oxidation. Scrub gently with a sponge or non-abrasive brush, then rinse thoroughly.

4. Rinse and Dry

After cleaning, rinse the surface of the aluminium with clean water to remove any residue. Use a soft, dry cloth to wipe the surface, ensuring it is completely dry to prevent water spots or streaks.

5. Polish for a Shine

If you want to restore the original lustre of aluminium, apply a commercial aluminium polish or a mixture of vinegar and water. Use a clean, soft cloth to buff the surface in a circular motion until it shines.

Tips for Maintaining Aluminium

Regular Cleaning: keep your aluminium surfaces clean by cleaning weekly or monthly, depending on usage, to prevent grime and oxidation buildup.

Avoid Abrasive Cleaners: never use steel wool or harsh chemicals, as they scratch or corrode the surface.

Protect from Harsh Environments: for outdoor aluminium items, consider applying a protective wax or coating to shield against weathering.

Address Stains Promptly: clean spills or stains as soon as possible to avoid long-term discolouration.

Use Protective Covers: for aluminium furniture or equipment, use covers during periods of non-use to minimise exposure to dirt and moisture.
