Abstract
A method for cleaning automotive or truck wheel surfaces. A cleaning composition containing an acid fluoride salt and having a pH of about 3 to 6.5 is applied to the automotive or truck wheel surface. The cleaning composition contains soluble salt in an amount which provides the composition with a molar ratio of soluble anion to hydrogen ion of about 3.5 or greater. This protects the wheel surfaces cleaned, including those of untreated aluminum, from corrosive attack by the acid fluoride salt.
