Hydrochloric ,acid, can be used to remove such heat-,treat, scale. A heavy-duty deoxidizer is the only type that can clean up the surface appearance of parts that are shot-peened, blasted or casted, and fluoride is the key to this deoxidizing method. A normal caustic etch could accomplish this, but it is much more ,difficult, to control the metal removal.
