Making LPs; What Goes Into the Mix
Here's an interesting thread that "Dr." Kirmuss must have read, prior to his session with MF, which I posted in the THE Show 2018 thread:

https://thelastfactory.com/vinyl-questions/explanation-of-how-vinyl-records-are-madepressed/


Much is left unsaid, and no "conclusions" are reached, in any case. But it is certainly food for thought.

Alternatives?
I am also reticent about some affirmations from Kirmuss.
Looking around and the Clearaudio double matrix professional SONIC, which seems to also have some "sonic" as option plus vaccum, but with an event worse price than Klaudio.

I think the Kirmuss + Pro-Ject Vinyl Cleaner VC-S (about US$500) would do a good pair. IDK if using cleaning "chemicals" after the ultrasonic cleaning would do any good (or bring any advantage) but the Pro-Ject one have the nice vaccum, and i like the fact of the plate just touching the record label.


As usual, it seems, the industry fail to bring the right product to solve the problem.

Think for yourself, do not be sheep.

"The Next New Thing"
Well, the top "business model" for years has been the business of business, rather than front line manufacturing, distribution, sales, or service, per se, and one consequence of this is a plethora of "products" that make more sense on spread sheets than they do in a particular application.  I don't see any of these things selling like hotcakes, so why not go for the Golden Ring ASAP?  Rather than effing with it and waiting to come up with a better record cleaner, they can just hire people to spread the word that it's "the best", and they put a price on it that "proves" it, ride it hard till it drops dead, then on to the "next new thing".

Not that I'm cynical about it...

UV bulb.
All this record cleaning subject left wondering if the record become exposed to UV light before (or after) the cleaning process it would bring any advantage. At least would kill all mold...

Also, not related with cleaning but maintenance, I was wondering since a while if this LP Flattener could work properly, or if that is more likely to damage the record?

I usually use the two glasses method but I would like to find something that work faster. Big Smile


Cheers!

UV + Plastic =
I think most plastics have trouble with UV, and some fungi are pretty tough, anyway.  The "idea" for me is to put the LP in a machine, turn it on, and return soon to a clean, dry LP that's ready to play on my turntable in my high-demands hi-fi system.  If "they" can build cars that drive themselves on our highways, certainly someone could come up with a better record cleaning machine.  Obviously, there just isn't enough money "invested" in hi-fi to attract and retain the personnel necessary to do a given job.  It's been like this since I can remember.  Oddly, there was once a ton of money invested in "records"; only, the money in records was the music (OK, the rights to the music...), not the records, themselves, nor the gear to play the records, once a given market was saturated.

The only time I used heat (the oven) to flatten an LP was many years ago.  Back then I used a Pickering (transcription) cartridge in a SME 3009 on a Rek-O-Kut TT, Leak Point One 6L6 amp driving modded Altec A-7 speakers.  I did not perceive any problem from the treatment, but I never did it again.  Now I mostly cull LPs before I buy them, and I use a vacuum holddown TT (SOTA Star).  Anything that won't flatten goes to the DAV (or it just sits there on my records shelves...).

Quite ironic.
Seem to be almost exactly same machine of "Dr. Kirmuss": HERE.

Rotisserie
The iSonic seems to be made by a company that doesn't care what you want to clean with ultra sound, they will rig something up for you.  I actually kind of like the "separate" motor/rotator that lifts out, even has its own electrical cord.  I have mixed feelings about the record label covers (the need for them).  This one says 35k Hz.  Kirmuss insists on 45k Hz.  Bring your own lint free cloth to dry the cleaner LPs emerging wet from either of them.

Since this is actually a thread about what goes into the LP plastic/vinyl formulation, it might be apropos to mention again that I've put a lot of alcohol on a lot of LPs over the past 55 years, and -  Kirmuss notwithstanding -  I haven't noticed any problems from this, despite using an extreme stylus profile at 2.6g.

He Actually say 35k Hz. See HERE.
I am start thinking he just got it added some nice stuff and made up (or got from iSonic) the literature. :/

Supply Chain
Well, there you go, all the better for Kirmuss, so his jobbers can fill the first surge of orders, no problem!  Like the song said, "If you can't be with the one you love, love the one you're with!"
