   Oxalic acid is sometimes used in the aluminum anodizing process, with or without sulfuric acid. [57] Compared to sulfuric-acid anodizing, the coatings obtained are thinner and exhibit lower surface roughness. Oxalic acid is also widely used as a wood bleach, most often in its crystalline form to be mixed with water to its proper dilution for use.
