How effective is the ultrasonic V-8 lp cleaner?

I suggest DIY.

All you need is an ultrasonic bath and a frame to hold a motorized spindle. If you are at all handy, it's not hard.

That's what I did. I use a German Elmasonic machine, industrial quality, running at 80 KHz. Does 4 records at a time. Results are far better than with my 16.5.

Allvinyl, that is the first test which I tried. I was perfectly ready to write off the cost of the US cleaner rather than damage my records.

Testing paradigm: cleaned two records thoroughly with 15 minutes of US. Treatment: I then immersed them half way in the US tank, without rotation, and let them cook for two hours. When I played the record, it played about a second of clean record and a second of cooked record, as good an ABA test as you could imagine. I heard no difference, nor did others who witnessed the test. What I did notice was an absence of high frequency distortion.

Lloyd, I am using a P-60H, rebranded as a Fisher Scientific.

Since my first posting above, I have returned to the cleaning method which I used in the test, 2 records at a time. The results are obvious: records sound clearer, and surface turbulence is observed between the records and on each side. With 4 records, there was no surface turbulence between records, hence limited cleaning action, leading me to conclude that at least one wavelength must be allowed between each record (3/4 inch for 80 KHz).
