Deoxidizing Aluminum as a Pretreatment
Deoxidizing Aluminum as a Pretreatment

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.
