A method of reducing defect heights of iron mound defects on a mill glass coated electrical steel, comprises contacting at least a portion of a surface of a mill glass coated electrical steel with an acidic solution for a contacting time sufficient to reduce an average height of iron defects on the surface to an average height in a range of 0 percent to 150 percent of the thickness of the mill glass coating, without effectively removing the mill glass coating. After contacting, the acid contacted mill glass coated electrical steel is rinsed with water and dried. |
