WebRust is a mixture of Iron oxides and hydroxides. I.e. Iron that has reacted with Oxygen. Rusting process is. 4Fe + 3O2 + 2H2O → 2Fe2O3 (H2O) An acid H+ will react with the hydroxides or oxide to give water and the :E^- will replace the O^-2 ligand on the Fe^+ atom giving an aquious (water soluble) salt which will run off with the water.
