How to Keep Aluminum from Oxidizing: Storing, Coating, and Sealing


Aluminum oxidation occurs when aluminum is exposed to oxygen in the air. This reaction can cause aluminum to corrode and break down over time, leading to structural damage. In this article, we’ll explore some effective methods of keeping aluminum from oxidizing.

Storing Aluminum

The best way to keep aluminum from oxidizing is to store it in a cool, dry environment. This will limit its exposure to oxygen and reduce the likelihood of corrosion. To further prevent oxidation, you should also avoid exposing aluminum to direct sunlight, which can accelerate the process.

When storing aluminum, it’s important to use protective packaging such as plastic wrap or bubble wrap. This will provide an extra layer of protection against oxygen and moisture. You should also avoid stacking aluminum products on top of each other, as this can cause scratches that may lead to rusting.

Coating Aluminum

Another way to keep aluminum from oxidizing is to coat it with a protective layer of paint or oil. This will create a barrier between the aluminum and the elements, preventing oxygen from coming into contact with the metal. Paint and oil are both relatively inexpensive and easy to apply, making them ideal for protecting aluminum.

In addition to preventing oxidation, coating aluminum with paint or oil can also help to preserve its appearance. This can be especially beneficial for decorative items such as sculptures or furniture pieces.

Avoiding Corrosive Substances

It’s important to remember that certain substances can have a corrosive effect on aluminum. Acids and alkaline substances can cause aluminum to break down more quickly, so it’s important to avoid contact with these materials. If you must work with corrosive substances, make sure to wear protective clothing and take proper safety precautions.

You should also be careful when using products containing chlorine, as this can also cause aluminum to corrode. If possible, opt for non-chlorine alternatives when cleaning or disinfecting surfaces.

Cleaning and Sealing Aluminum

Regularly cleaning aluminum surfaces with soap and water can help to keep them free from corrosion. It’s also a good idea to apply a corrosion-inhibiting primer before painting, as this will provide an extra layer of protection against oxidation. For outdoor surfaces, you may want to consider applying a clear sealant to further protect the aluminum from the elements.


By following these tips, you can prevent aluminum from oxidizing and ensure that it lasts longer. The key is to store aluminum in a cool, dry environment, coat it with paint or oil, avoid corrosive substances, and regularly clean and seal its surface. With a little bit of care and attention, you can keep your aluminum looking great for years to come.
