Abstract
Described are methods of removing aluminum fluoride contaminants from aluminum, anodized aluminum, and sprayed ceramic surfaces. Hydrofluoric acid, long known to be effective at removing certain contaminants, has not been used to dissolve aluminum fluoride on aluminum-containing surfaces because the hydrofluoric acid strongly attacks such surfaces, and consequently damages sensitive components. Methods used in accordance with some embodiments remove aluminum fluoride using a mixture of hydrofluoric acid and one or more anhydrous acid. Suitable anhydrous acids include acetic acid.
