Removing Oxidation from Aluminum: 8 Proven Methods

Introduction

Aluminum is a very popular material for many things like window frames, siding, furniture, and even automotive components. However, aluminum is susceptible to oxidation, which can cause the surface of the metal to become discolored and dull.

Oxidation is the process by which oxygen reacts with a substance, usually a metal, to form an oxide. In the case of aluminum, oxidation creates a thin layer of aluminum oxide that can make the metal look dull and worn out. Fortunately, there are ways to remove oxidation from aluminum and restore its original shine.

Clean with Baking Soda and Vinegar

One of the easiest and most cost effective ways to remove oxidation from aluminum is by using a mixture of baking soda and vinegar. This method is particularly useful for small items that are not heavily oxidized.

Materials Needed:

• Baking soda
• White vinegar
• Soft cloth
• Small brush (optional)

Step by Step Instructions:

1. Mix together equal parts baking soda and white vinegar to form a paste.
2. Apply the paste to the aluminum surface with a soft cloth or small brush.
3. Allow the paste to sit on the aluminum surface for several minutes.
4. Rinse off the paste with water.
5. Dry the aluminum surface with a clean cloth.

Use a Brass Brush and Detergent

For more stubborn oxidation, a brass brush and detergent may be necessary to remove it. This method is particularly useful for larger aluminum surfaces such as window frames and siding.

Materials Needed:

• Brass brush
• Mild detergent
• Soft cloth
• Garden hose

Step by Step Instructions:

1. Mix together a solution of mild detergent and warm water.
2. Soak the brass brush in the solution.
3. Scrub the aluminum surface with the brass brush.
4. Rinse the aluminum surface with a garden hose.
5. Dry the aluminum surface with a soft cloth.

Polish with a Soft Cloth and Metal Polish

Once the oxidation has been removed, you can use a soft cloth and metal polish to restore the aluminum’s original shine. This method is best used for smaller aluminum items such as furniture.

Materials Needed:

• Soft cloth
• Metal polish

Step by Step Instructions:

1. Apply the metal polish to the aluminum surface with a soft cloth.
2. Rub the polish into the aluminum with a circular motion.
3. Buff the aluminum with a clean cloth.

Apply Lemon Juice and Salt

Another simple and cost effective way to remove oxidation from aluminum is by using lemon juice and salt. This method is best used for small items such as jewelry.

Materials Needed:

• Lemon juice
• Table salt
• Soft cloth

Step by Step Instructions:

1. Mix together equal parts lemon juice and table salt to form a paste.
2. Apply the paste to the aluminum surface with a soft cloth.
3. Allow the paste to sit on the aluminum surface for several minutes.
4. Rinse off the paste with water.
5. Dry the aluminum surface with a clean cloth.

Use a Commercial Aluminum Cleaner

If you want a more efficient and professional way to clean your aluminum, then you may want to consider using a commercial aluminum cleaner. These cleaners are specifically designed to remove oxidation and restore the original shine of aluminum.

Materials Needed:

• Commercial aluminum cleaner
• Soft cloth

Step by Step Instructions:

1. Apply the aluminum cleaner to the aluminum surface with a soft cloth.
2. Rub the cleaner into the aluminum with a circular motion.
3. Allow the cleaner to sit on the aluminum surface for several minutes.
4. Rinse off the cleaner with water.
5. Dry the aluminum surface with a clean cloth.

Try a Mild Abrasive

For heavily oxidized aluminum, a mild abrasive may be necessary to remove the oxidation. This method is best used for large aluminum surfaces such as siding and window frames.

Materials Needed:

• Mild abrasive
• Soft cloth
• Garden hose

Step by Step Instructions:

1. Apply the mild abrasive to the aluminum surface with a soft cloth.
2. Rub the abrasive into the aluminum with a circular motion.
3. Rinse the aluminum surface with a garden hose.
4. Dry the aluminum surface with a clean cloth.

Use Oxalic Acid

Oxalic acid is another effective way to remove oxidation from aluminum. This method should only be used as a last resort, as oxalic acid is a corrosive chemical and can damage the aluminum if not used properly.

Materials Needed:

• Oxalic acid
• Protective gloves
• Safety glasses
• Soft cloth
• Garden hose

Step by Step Instructions:

1. Wear protective gloves and safety glasses.
2. Mix together a solution of oxalic acid and warm water.
3. Soak the soft cloth in the solution.
4. Apply the solution to the aluminum surface with the cloth.
5. Allow the solution to sit on the aluminum surface for several minutes.
6. Rinse the aluminum surface with a garden hose.
7. Dry the aluminum surface with a clean cloth.
