Kirmuss 'In the Groove' Ultrasonic Record Restorer - Upscale Audio Edition

@jeffreylee   "What did I say that's misleading?"

You said, "There’s no difference between the way US machines operate. Transducers create bubbles, the bubbles clean. That’s it."

That is so silly that you contradicted it in the next sentence. Then you ignore the fact that cleaning efficiency depends on both particle size and frequency. You also do not discuss the particle size usually encountered on records, and hence which frequency a record cleaner should use, and whether or not jewelry cleaners use this frequency.

You do not discuss power generated. Or power at the record face. Or distribution of power at the record face. Or QC. You do not discuss how closely the unit which has been delivered, adheres to spec.

You do not discuss the cleaning solution, type of surfactant required, rinsing, etc.

That do?

@larsman US is a common abbreviation for ultrasonic, bud. It has been used many times in this very thread.

@ljgerens While I don't necessarily advocate for using tap water, others including Neil Antin do. I offered it as a possible remedy to rinse detergent if used in the US machine.   In my post I recommended rinsing with Distilled water after using tap water.  Since the water beads on the vinyl surface, there should be little transfer of contaminants to the record surface unless allowed to dry.  A distilled water rinse eliminates the problem, since the contaminants are clearly water soluble. Using detergent without a rinse would create a much bigger problem.
