[78-L] Ultrasonic cleansing of records?

[Milan P Milovanovic]

Hello to all members of 78online list.

Just wanted to hear is there any benefit (in terms of quality) of using 
ultrasonic baths for cleaning 78s? Some people told me that this method has 
some advantages over usual record cleaning procedures. Any experience with 
this? Laminated Columbias with cracked surfaces, flaking acetates, cardboard 
core acetates or Edison Diamond discs probably are not records to clean them 
wet, but what about other more common (shellac) records?

Thank you,

Milan
