Perfect Vinyl Forever

 

@wolfie62 Dogberry is right. US can’t cure abused records, but US gets the most from the records you have.

I run a high power lab unit at 80KHz, 2 records at a time. If you fill a low power unit running at 40 KHz with 10 records, you won’t get much cleaning.

Full disclosure: ESL system, air bearing turntable. I think I’d detect a null effect.

I got my 10L US tank in 1999, from a closed down lab where I worked. Made in USA, used for prototyping metals prior to engraving, chemical etching, coating, printing of SS, silver, copper, brass, bronze, gold alloy, gold-clad, titanium. My unit has digital settings for frequency and power: 36 kHz-100 kHz, 100 watts - 1000 watts. I tried many frequencies and power levels. It even does programmable frequency sweep cleaning. 

So your ASSUMPTIONS about my unit are way off base! And BTW, US cleaning is far less effective on soft materials than on metals. So you can keep your assumptions to yourselves. You don’t have the expertise to be making the bad judgements that you’re casting out here.

I found a nail in the bottom of my shoe this morning

Wolfie, I am just curious.  You stated that US cleaning is naught but a fad.  Then in the same post you said you had some LPs cleaned professionally and that you were dissatisfied.  This led you to clean them yourself, presumably with your US cleaner described above in your second post.  You were happier with those results.  And now here you are touting your US cleaner.  So, which is it?  Do you think it’s a passing fancy or a real “thing”?  Also, what is the point in saying that US cleaning is less effective on soft materials than on metals?  By inference, are you suggesting again that US cleaning is not so effective on LPs?  But why even say that; if you give your cleaner enough juice it could probably reduce an LP to particulate matter.

I was in the same boat as you and decided to use PVF exclusively for cleaning all my records, new or used. I think the service is great, but I do have some records with a few clicks and pops still. So perhaps Perfect Vinyl Forever isn’t so "perfect". But I’ll keep using them.

I own and occasionally use an Ultrasonic cleaner.  Most of the time I clean with an old Nitty Gritty machine that I converted to totally manual operation.  I spin the record by hand to "scrub" in both directions and I then thoroughly vacuum away the cleaning fluid; again done with manual rotation.  For almost all my records, this kind of cleaning is sufficient.  But, on a small handful of used records I've purchased, even the most thorough cleaning did not get all of the crap out of the groove.  I thought the noise and distortion on some of these records was from groove damage.  But, following ultrasonic cleaning a small number of records improved dramatically, evidently from removing gunk that was practically glued to the record.  It is such a small number of records that cleaned up better with ultrasonic cleaning that I do not think it is an essential tool; but, it is something that does work.
