.... The applicability of these methods is determined by part shape, required surface finish, and allowable loss of gage or dimension. However, abrasive cleaning can remove some metal and degrade surface finishes. Therefore, flash pickling is used more often than abrasive cleaning to remove tarnish. A typical flash...
