Abstract
The coefficient of friction of aluminum can surfaces after alkaline cleaning and drying can be substantially reduced by adding to the alkaline cleaner a mobility enhancing additive, preferably a surface active quaternary ammonium salt with hydroxyethyl substituents on the quaternary nitrogen atoms. A can surface suitable for automatic conveying and high quality lacquer or printing ink adhesion can thereby be obtained, if desired without including any substantial fluoride content in any treatment stage.
