We Vinyl Ultrasonic or Vacuum Cleaner?

Correction:

 that cannot be too slow (less than about 1-rpm)

Change to read:  "...that can be too slow (less than about 0.5-rpm)..."

FWIW:  Record speed and be too fast depending on the tank size and number of records clean at one time and if the tank is filtered.

@dogberry Dang. That thing looks like a Roomba for records!

Do you use that after every record cleaning? Or in between? Or both. 

Ever see that DS Audio Ionizer? It shoots ozone out over records. $1700. Crazy. 

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.
