Scrubbing with wire brush will not remove acid residue anyway. Just wash with mix of 50% baking soda and water using a stiff brush. Soda neutralizes the acid. You only need to make up a teaspoon of soda and the water. When done neutralizing, wash carefully with running water to remove the soda residue.
