Abstract
A combination of phosphonoinidazoline at surfactant, soluble polyvalent metal ions, and a metal etching component, which is tolerant of aluminum cations and aluminate anions, when used as the Stage 4 rinse for aluminum cans provides good can mobility and good resistance to loss of mobility during heating of the treated cans to a greater extent than is normal during high speed processing. A concentrate of the active ingredients of such a Stage 4 treatment also maintains its effectiveness for longer than do similar produels when stored at high ambient temperatures.
