Cleaning anodized aluminum surfaces incorrectly can indeed lead to corrosion. Anodized aluminum possesses a protective oxide layer that helps resist corrosion; however, if the cleaning method or chemicals used are too abrasive or not suitable for anodized surfaces, this protective layer can be damaged.

When the anodized surface is compromised, the underlying aluminum becomes exposed and can react with moisture and environmental elements, leading to corrosion. Also, using strong alkaline or acidic cleaners can weaken the anodic coating, making it less effective in preventing corrosion.

Enhancing the surface finish, strengthening the aluminum structure, or improving paint adhesion would not typically occur if the anodized surface is cleaned improperly. In fact, the opposite is likely true, as damage to the anodized layer can result in a poor surface finish and diminished structural integrity.
