Still tank methods of cleaning aluminum sheets, castings or bar stock prior to anodizing.
Anodizing consists of treating aluminum electrolytically as the anode in an acid solutions
to produce an oxide film. The oxide film, while providing a surface, which is suitable for painting,
lacquering, or dyeing, is also more resistant to corrosion and abrasion.
Anodizing processes that require that the aluminum surfaces be free of any oil, dirt, grease, etc., which
will interfere with obtaining a uniform coating. Since aluminum is attacked by uninhibited alkaline
cleaners, an alkaline cleaner with an inhibitor is used.
