Yes, KBS Klean is ideal for cleaning unpainted aluminum surfaces. The best practice is to mix 25-Parts Hot Water and 1-Part KBS Klean and clean with the use of a very soft non-abrasive cleaning pad. Rinse the KBS Klean solution immediately making sure you do not let it sit on the surface and dry in a way that minimizes any water stains.
