ultrasound record cleaning machine damaged my records

Cleeds, I drive a well known German automobile. Can you name it with any certainty? No. 
 

I would have guessed that US might damage an LP by affecting high treble frequencies first, since those are encoded by the most tortuous grooves. So I’m a little surprised at this report. Also 40 kHz and 60W do not seem excessive. So I’m wondering whether his generator is out of whack, delivering higher energy than rated. Or whether this is a red herring.
 

I make no secret of the Label I now give my manually cleaned records using the PAVCR Manual Cleaning Method, as being Purified as the end product after the cleaning process.

I attribute 90%+ to this end result as being the Mixture for a Cleaning Solution that Neil Antin carefully calculates.

In posts in other threads, I have made it known I bought in extra ancillaries to enable myself to produce the Solutions to be used to a very accurate ratio for the mixture.

The mixture ratio for the cleaning solution are critical, the tools are aids to optimise the impact of the solution on the material being cleaned.

The following can be challenged quite outwardly with rebuttal. 

How many US Tanks have been filled / are filled / to be filled, with Solutions that are with ratio's for the mixture of the Cleaning Solution, that does not enable the Solution to perform to the necessary requirements ?

It does seem Cavitation used for Cleaning is optimised when manifesting in a particular solution?

It does seem Cavitation manifesting in a non-optimised solution, does not have the cleaning capability to effectively stop cleaning solution residual forming in the LP Groove, to the point the presence of the residual is audible?   

If the machine in question is a Humminguru, there was a YouTube video I watched where the Humminguru was used to clean an album over 20 times, and there was significant damage.  The other record cleaner (might have been a Degritter) did not cause such damage even after so many cleanings.  One line of thinking is that the lower frequency US machines are potentially not as gentle to the vinyl as the higher frequency machines, and ones that have the transducers located very closely to the vinyl are potentially more damaging, and there are machines that oscillate across multiple frequencies like the AudioDesk that should be safer.  I also saw an US piece that described how the technology could, if not implemented properly, damage the vinyl by removing particles and this was proven in testing.   I was going to go with the Humminguru to replace my AudioDesk until I saw that YouTube review and starting be concerned about my valuable collection (some of which are irreplaceable) being damaged.  I liked what I heard regarding the AudioDesk upgrades to the pump, refined US approach, etc. and got one at a substantial discount from Ultra Systems even though the one that broke was 9 years old and that unit was one that replace a machine that I had bought 3 years prior.  I thought the new replacement unit price and upgrades made for a reasonable deal, and it would be better to pay more and protect my collection than going with an US machine that is a newer design, as much as I was intrigued by the Humminguru concept, positive reviews, and relatively affordable purchase price.  I figure if the AudioDesk lasts several years, prior to replacing again, the cost per month and utility will be justified.  Hopefully we get confirmation of the unit in question that is damaging vinyl.

I'll stick with my SpinClean, thank you.

It is seemingly the Solution used for cleaning that is the key to the end result being able to substantially impress or not, tools used are merely tools being used.

If I were to change a Cleaning Solution it would be one identified by Neil Antin or someone with Neil Antin credentials, offering the Mixture Ratio for the selected substances.

My days of producing a drip or two of this, splurge of that, diluted with this, to produce a potion where info is supplied from a variety of sources, even the manufacturers. When there is no real understanding of the qualities that are on offer from what is produced, are very much over. 

I strongly suggest anybody putting their faith in the Tools and not the cleaning solution, have a rethink, and discover the mixture / solution that really does benefit the cleaning process.
