Off to the vinegar bath for mine :)
EDIT: OK deoxidized and sitting in a bath of Mayhem X1 until I can install them. 2 things I noticed: one of the VRM screws that attaches the delrin to the copper was shorter than the rest. Also, there was some reside in the corners of the interior cavity of the VRM block that looked like jeweler's rouge. q-tip took care of it.
Other than that they look good.
