Topic: Vibe polish pre-anodize

Any one have a reccomended process to remove/clean corncob or walnut shell from ID threads prior to anodizing?  We have strayed away from vibe polishing aluminum over the years because our anodize vendor bright dipped and said it wasn't neccesary.  In the past we had "organic contamination" issues (due to the media) from another vendor that did not bright dip and required a polished finish pre-anodize.
