ALUMINUM BRITE SOPA is a mildly acidic cleaner and brightener for aluminum surfaces. It is a combination of organic surfactants, solvents and inorganic acids. It is designed to etch aluminum surfaces at a controlled rate removing the oxides and other contaminants. Its slow action helps prevent streaking of large aluminum surfaces and allows the maximum in cleaning action. ALUMINUM BRITE SOPA will remove road film and exhaust carbon with ease.
