Abstract
Dried resins, such as polyester sheet molding resins, are effectively removed from metallic surfaces by a cleaning composition prepared from a cleaning concentrate comprising an an organophosphoric ester surfactant; a nonionic surfactant, such as an acetylenic alcohol or diol, or a polyoxyethylene oxide ether of an alkyl phenol or alkanol; and a water-miscible solvent such as a 2-pyrrolidone, tetrahydrofurfuryl alcohol, or an ethoxylated THFA or furfuryl alcohol. The cleaning compositions can contain detergent builders, chelating agents, and other optional components.
