Claim:
1. Composition in combination with a steel container for at least storing said composition, comprising: (a) a composition including about 0.5 to about 20 wt. % of a chelating system, about 0.25 to about 10 wt. % of at least one solvent, and about 60 to about 98 wt. % water; and (b) a steel container structured and arranged to at least store said composition; wherein said container comprises an interior steel wall including thereon (1) a metal passivation layer comprising (i) a metal layer or (ii) a metal layer and metal oxide layer and (2) a polymer liner over said metal passivation layer; wherein said chelating system includes a chelating agent which has an affinity to metal of said metal passivation layer such that said affinity is sufficiently low so as not to complex with said metal so as to delaminate said polymer liner from said metal passivation layer, wherein said interior steel wall does not have a tin coating thereon.
