| − | Using battery acid to clean concrete can crumble and flake your concrete surface. It doesn't "clean" concrete -- it '''dissolves''' it. The acid soaks into the concrete, and will continue to damage it until it is neutralized. Water doesn't "neutralize" battery acid, it simply '''dilutes''' it. In fact, sulfuric acid produces heat when it is introduced to water. The resulting exothermic reaction can blow acid all over your body, leading to acid burns that quickly dissolve your flesh. | + | Using battery acid to clean concrete can crumble and flake your concrete surface.
