Good morning:
          I guess I've never heard that particular jargon for it, but we 
     used to see it, particularly on Duroid-type materials, with the 
     impingement of the jets in a jet pumice scrubber and later with the 
     aluminum oxide jet scrubber. It's a good argument for having a chem 
     clean optional cleaning process, if you can stand the redundancy.
