<p>A method and system for removing contaminating iron from an acid pickle bath. The method comprises the steps of removing at least a portion of the acid pickle solution containing an amount of contaminating iron therein from a primary acid pickle bath, raising the pH of the at least the portion of the acidified acid copper solution with a pH adjuster to a level which is conducive to the precipitation of iron, precipitating the contaminating iron from the acidified acid copper solution, and acidifying the acid copper solution back to operating conditions for the system. Once the portion of the acid pickle solution has been treated, it is returned to the primary acid pickle bath.</p>
