    Abstract: A composition useful as a rinse aid for metal surfaces and for improving the mobility of formed metal surfaces is described. The composition comprises(A) from about 10 to about 90% by weight of at least one nonionic polyoxyalkylene glycol comprising poly(oxypropylene) hydrophobic groups and poly(oxyethylene) hydrophilic groups, and(B) from about 10 to about 90% by weight of at least one alkoxy derivative of at least one ethoxylated and propoxylated glycol, and particularly at least one nonionic polyoxyalkylene glycol comprising poly(oxypropylene) hydrophobic groups and poly(oxyethylene) hydrophilic groups. A process is also described for improving the drainage of water from metal surfaces and for improving the mobility of formed metal surfaces. The process comprises contacting said metal surface with an aqueous composition comprising water and the above-described composition. The composition and process of the present invention result in lower oven temperatures and reduced coefficient of friction which results in improved mobility.
