Doug, I agree, common sense dictates that a wand style machine can be a source of re-contamination. But that those inherit qualities can be lessened with a few additional steps. I always assumed as well, the abrasive qualities by physical contact could as well create damage to the vinyl surface, and groove.
A pre-cleaing/pre-dusting before the record reaches the RCM will lessen what the Wand encounters. Periodic replacement of the Vacuum Wand and/or protective velvet strips.
An additional wand dedicated for rinse only will help, and of course the obvious, is a simple additional rinse step at the end.
I understand as well, that groove silence, or the omission of clicks-pops to be used as a gauge to judge a cleaner's-rinses efficiency.
That clicks-pops can be damage, or anomalies in the vinyl that no cleaner, or RCM will magically remove.
