Cast Aluminum Patio Furniture Turning White: Causes and Solutions

Cast aluminum patio furniture is a popular choice due to its durability and style. However, over time, it can start to turn white, which can be unsightly and affect its functionality.

Causes of White Oxidation

The white oxidation on cast aluminum patio furniture is caused by a reaction between the aluminum and oxygen in the air. This reaction creates a thin layer of aluminum oxide, which is a protective layer that helps prevent further corrosion. However, in some cases, the aluminum oxide can become too thick and cause the furniture to turn white.

There are several factors that can contribute to the white oxidation of cast aluminum patio furniture, including:

Exposure to the elements: Cast aluminum furniture that is exposed to the sun, rain, and other elements is more likely to develop white oxidation.
Use of harsh cleaning chemicals: Using harsh cleaning chemicals, such as bleach or chlorine, can damage the protective aluminum oxide layer and make the furniture more susceptible to white oxidation.
Improper maintenance: Not properly maintaining cast aluminum furniture can also lead to white oxidation. This includes not cleaning the furniture regularly and not applying a protective coating.

Solutions for White Oxidation

Fortunately, there are several things you can do to remove white oxidation from cast aluminum patio furniture and prevent it from happening in the future:

Clean the furniture regularly: Use a mild cleaning solution and a soft cloth to clean the furniture. Avoid using harsh chemicals or scrubbing pads, as these can damage the finish.
Apply a protective coating: Once the furniture is clean, apply a protective coating to help prevent future oxidation. There are several different types of protective coatings available, so choose one that is specifically designed for cast aluminum furniture.
Keep the furniture out of the elements: If possible, keep your cast aluminum patio furniture out of the elements to reduce its exposure to sunlight, rain, and other harsh weather conditions.

By following these tips, you can keep your cast aluminum patio furniture looking its best for years to come.
