Phosphoric Acid Wash

We have used Phosphoric acid 85% to wash down corroded steel, unfortunately this has reacted with galvanized grid mesh. Does anyone know how to rectify this problem - currently the grid mesh looks terrible!

No, those corrosion products are pretty friable, and there is probably not much zinc left on the grid.
