Aluminum White Stain Problem: Clear, Practical Prevention

Summary for aluminum white stain problem Discussion

Aluminum white stain problem is raised by Frankie, who says his company sees white stain forming on aluminum parts after storage and asks how to reduce it and what cleaner can remove the affected areas without harming the appearance. The only answer in the thread, from TDK, states plainly that aluminum corrodes and that the white material is corrosion product. According to TDK, the way to stop it from forming is to protect the metal with clearcoating or anodizing. The reply does not recommend a specific solvent for cleaning already-stained parts, and it implies that prevention is the real fix rather than a cleanup-only approach. The discussion is brief and one-sided, with no conflicting advice offered.
