We Vinyl Ultrasonic or Vacuum Cleaner?

Not after cleaning, but before each disk goes on the turntable. It makes dust particles unstick so that my blower brush removes them easily.

I modified my Humminguru so that the discharge water is routed thru tubing to a milk jug on the floor behind my cleaning station which I then only have to empty occasionally. I rinse and dry on a VPI. I'm not concerned about steps so I use a marked pyrex measuring cup for new cleaning fluid that I heat with a coffee warming coil and a dial thermostat before use.  Not sure if it adds anything but the expensive units mostly all heat the solution so I do too.

I always clean any new or used purchase in my Klaudio record cleaner before playing. I have a very good collection of Windham Hill albums. 

OP…As in most things hi-fi the answer is BOTH….Using both give you the best vinyl listening experience possible for a given record.

FWIW Chad Kassem was asked if he cleans new records prior to their initial play. He stated that he brushes his records and does not use another method initially. It was not clear whether he was referring to Analog Production products only. Interesting perspective.
