    Abstract: Disclosed is a process for cleaning and applying a mobility enhancer to a metal container, preferably to an aluminum can, the process comprising the steps of: (a) contacting the container with an aqueous acidic prewashing solution; (b) contacting the container with an aqueous acidic or alkaline cleaning solution; (c) rinsing the container with an aqueous acidic dispersion (d) rinsing the container with an aqueous acidic dispersion comprised of a mobility enhancing composition, the mobility enhancing composition comprising (i) at least one wax; and (ii) at least one surfactant, in an amount sufficient to decrease the coefficient of static friction on the outside surface of the container, and to provide a substantially water-break-free surface thereon. Processes for cleaning and applying a mobility enhancer to a metal container wherein the mobility enhancing composition described above is applied to the container during a conditioning rinse or conversion coating step, or during one of several water rinsing steps are also disclosed. The mobility enhancing composition provides improved mobility of aluminum cans as they are conveyed along trackwork from the can washing operation to other remote operations in a can manufacturing facility without adversely affecting subsequently applied internal and/or external can coatings.
