Why May You Want to Polish Anodized Aluminum?

1 . To Restore Its Appearance

Anodized aluminum is a popular material used in various industries due to its durability and resistance to corrosion. However, over time, it may develop scratches, swirl marks, or lose its shine due to exposure to harsh environmental factors. Polishing anodized aluminum can help restore its original appearance and make it look brand new again.

2 . To Remove Stains and Contaminants

Anodized aluminum can also become discolored or stained over time, especially when exposed to chemicals or pollutants. These stains can be difficult to remove with regular cleaning methods, but polishing can help eliminate them and restore the surface’s clean and uniform appearance.

3 . To Improve Its Performance

Polishing anodized aluminum not only enhances its appearance but also improves its performance. The polishing process can help smoothen out any rough spots or imperfections on the surface, making it easier to clean and maintain. This can be especially beneficial for industries that rely on anodized aluminum for its functional properties, such as aerospace and automotive.

4 . To Protect It From Further Damage

In addition to restoring its appearance and improving performance, polishing anodized aluminum can also provide a protective layer. The polishing process often involves using specialized compounds that not only remove imperfections but also leave a protective coating on the surface.

This helps prevent future damage from environmental factors and prolongs the lifespan of the material.

How to Polish Anodized Aluminum in 5 Easy Steps

Step 1: Gather your Supplies

Before you begin polishing, it is important to gather all the necessary materials. Here are some items that you will need:

• Anodized aluminum cleaner or polish (such as Flitz or Mothers)
• Soft cloth or rag
• Toothpaste (optional)
• Water
• Microfiber towel

Step 2: Clean the Surface of the Aluminum

The first step to polishing anodized aluminum is to clean the surface. Use a soft cloth or rag and some water to wipe down the aluminum thoroughly. This will remove any dirt, dust, or grime that may be on the surface.

Step 3: Apply Anodized Aluminum Cleaner

Next, it’s time to apply an anodized aluminum cleaner or polish. Follow the instructions on the product label, and apply the cleaner in a circular motion with a soft cloth or rag. This will help to remove any remaining dirt or stains on the surface of the aluminum.

Step 4: Use Toothpaste for Extra Shine (Optional)

If you want to add an extra shine to your anodized aluminum, you can use toothpaste. Simply apply a small amount of toothpaste to the surface and gently rub it in with a soft cloth or rag. The mild abrasive in the toothpaste can help to remove any remaining stains or dullness on the aluminum.

After you have finished polishing, use a clean microfiber towel to wipe down and dry the aluminum. This will help to remove any excess cleaner or toothpaste and leave your anodized aluminum looking shiny and new.

Tips for Maintaining Anodized Aluminum

Now that you know how to polish anodized aluminum, it’s important to also know how to maintain it. Here are some tips to keep your anodized aluminum looking its best:

1 .  Clean Regularly

Regular cleaning is essential for maintaining the shine and luster of anodized aluminum. Use a mild soap or detergent with warm water and gently scrub the surface with a soft cloth or sponge. Avoid using abrasive cleaners or tools that can scratch the surface.

2 . Rinse Thoroughly

After cleaning, be sure to rinse the aluminum thoroughly with clean water. This will remove any residue from the cleaning solution and prevent it from drying on the surface.

3 . Dry with a Soft Cloth

To avoid water spots, dry the aluminum with a soft cloth or towel after rinsing. Make sure to use a lint-free cloth so that you don’t leave any fibers behind on the surface. Also, avoid using paper towels as they can leave scratches on the anodized finish.

4 . Use a Non-Abrasive Polish

If your anodized aluminum needs a little extra shine, use a non-abrasive polish specifically made for anodized surfaces. Apply the polish with a soft cloth and buff it in a circular motion. Then, use a clean cloth to wipe away any excess polish.

5 . Avoid Harsh Chemicals

Avoid using harsh chemicals on anodized aluminum as they can damage the finish. This includes bleach, ammonia, and acidic cleaners. Stick to mild soaps or specialized anodized aluminum cleaners.

6 . Protect from Scratches

Anodized aluminum is more scratch-resistant than non-anodized aluminum, but it can still get scratched. To prevent scratches, avoid using abrasive tools or cleaners and be careful when placing objects on the surface.

7 . Store Properly

When storing anodized aluminum items, make sure to protect them from scratching or damage. You can wrap them in soft cloth or bubble wrap, and store them in a clean and dry place.

8 . Regular Maintenance

Lastly, regular maintenance is key to keeping your anodized aluminum looking shiny and new. Make it a habit to clean and polish your aluminum items every few weeks or as needed, depending on the amount of use they receive.
