Well, ultrasonic cleaning does work (on plastic, I think). The question is, does it clean anything
that a brush and solution won't clean AND does it pock, pit or other wise damage the vinyl? I'd
think it's possible for an ultrasonic cleaning system powerful enough to dislodge dirt stuck in a
record groove to damage the groove wall, which is uneven by nature. But I'm no expert in ultrasonic
The previously mentioned audio magazine writer also likes the "vinyl demagnetizer" machine, but no
one has yet shown any scientific proof that any vinyl carries magnetic fields strong enough to
effect the internal mechanics of any phono cartridge. For what it's worth, I took a record and
exposed it to a bulk-erasing cycle on an old Ampex professional tape-eraser. I could hear no
differences between before and after. I also couldn't measure any as far as noise floor of peak
level. The magnometer I have couldn't measure a magnetic field on the vinyl before or after, so I
suspect if there is any inherent magnetism in the black particles in the vinyl (the theory proposed
by the expensive accessory's manufacturer), it's not a strong enough field to effect cartridge
