摘要：
A cleaning process for recovering an anodized aluminum part is particularly useful when the part has been exposed to a fluorine-containing plasma in etch reactor. The part is bathed in an agitated solution of a fluoride acid, such as ammonium fluoride, which converts aluminum fluoride to a soluble fluoride. The part is rinsed in water. The pores of the cleaned anodization may be resealed by a submerging the part in hot agitated deionized water.
