Protecting Aluminum from Corrosion: Steps and Benefits


Aluminum corrosion occurs when the metal is exposed to air or moisture, leading to oxidation and deterioration. It is a common problem with aluminum surfaces, as the metal is naturally prone to corrosion. Without proper protection, aluminum can quickly become unsightly and unsafe.

Steps for Protecting Aluminum from Corrosion

The best way to protect aluminum from corrosion is to take preventive measures. Here are some steps you can take to keep your aluminum surfaces looking great for years to come.

1. Clean the aluminum regularly with a mild detergent and water solution. Regular cleaning helps remove dirt, grime, and other contaminants that can speed up the corrosion process. Use a soft cloth and a mild detergent to wipe down the aluminum surface. Rinse with clean water and dry thoroughly.

2. Apply a protective coating such as anodizing or powder-coating to the aluminum surface. Anodizing is a process that creates an oxide layer on the aluminum surface, which helps protect it from further corrosion. Powder-coating is a similar process, but it uses a dry powder instead of liquid. Both processes help create a barrier between the aluminum and the elements.

3. Seal any cracks or crevices in the aluminum with a sealant. Sealing the cracks and crevices in aluminum will help reduce the chance of corrosion. Use a sealant specifically designed for aluminum. This will help keep moisture and other contaminants out of the cracks and crevices.

4. Use a corrosion inhibitor like an oil-based paint or wax. A corrosion inhibitor helps slow down the corrosion process by creating a barrier between the aluminum and the elements. Oil-based paints and waxes are commonly used as corrosion inhibitors. Be sure to apply the inhibitor according to manufacturer’s instructions.

5. Regularly inspect the aluminum for signs of corrosion. Inspecting the aluminum regularly will help you catch any signs of corrosion before it becomes a major issue. Look for discoloration, pitting, or flaking of the aluminum surface. If you find any corrosion, take steps to repair it immediately.

6. Store aluminum in a cool, dry environment. Storing aluminum in a cool, dry environment will help reduce the chances of corrosion. Avoid storing aluminum in damp or humid areas, as this can accelerate the corrosion process.

7. Use stainless steel fasteners when attaching aluminum components. Using stainless steel fasteners when attaching aluminum components will help reduce the chances of corrosion. Stainless steel is less susceptible to corrosion than aluminum, so it will provide extra protection.


By taking these steps to protect aluminum from corrosion, you can ensure that your aluminum surfaces will stay looking great for years to come. Regular cleaning, coating, sealing, and inspecting are all important parts of keeping aluminum in good condition. By following these steps, you can avoid costly repairs and prolong the life of your aluminum surfaces.
