Process for treating an aluminum can using a mobility enhancer

A process for washing an aluminum can, said process comprising the steps of:

• prewashing said can;
• decreasing the coefficient of static friction on an outside surface of said can to about 0.9 or less and providing a substantially 100% water-break-free surface by washing said can using an acidic or alkaline aqueous composition, said composition comprising a mobility enhancing amount of the product made by the reaction of at least one carboxylic acid or acid-producing compound with ammonia, at least one amine, or at least one alkali or alkaline-earth metal, and a surfactant;
• rinsing said can using an aqueous acidic composition;
• rinsing said can using deionized water;
• drying said can;
• and
• conveying said can along a conveyor or trackwork.
