There are uses of a US Tank that can cause damage to materials.
In my early days if setting up a tank, I was advised to put Aluminium Foil in to it for a period of time and check to see when it perforates.
The idea being to substantially reduce cleaning time for the LP, to not expose the LP to a cleaning period that has caused the Perforation in the Aluminium.
Today there are much better guidance's available for the different Cavitation Dimension available to be produced from different Hz Ultrasounds.
The question is, How accurate is the guidance, especially considering Vinyl is being Cleaned and certain Vinyl Materials are valued albums, that can have multiple years usage.
Does a Unused Album or Brand New Album need the exact same US treatment, as an Album that might have had a 100+ replays? Maybe the 100+ Hours Album has a wear damage that is inaudible, but a US treatment can be a detriment to such a condition being present. This is all conjecture but has to be on the table for discussion, as their only seems to be one type of info out there, Tank Degas, Tank Temp, Rotation Speed and Clean Time. The guidance all seems to be generic for the differences in the Hz of a Tank and Cavitation Dimension.
I eventually opted out, and use the Neil Antin Manual Cleaning Method, I now have specific instruction using a formula for a mixture that is extremely Vinyl Friendly.
Additionally I now have LP's that are Clean in a way not before experienced, that I refer to as Purified.
I have a 40 Year owned Album that was put through the Wringer of being Teen Owned and a Party Favourite.
The Album was in the end unusable and kept only for Sentiment, in use it was seemingly able to destroy a Styli. After being impressed with the Manual Clean, I dedicated Six Minutes of my time to do a Manual Clean on the long time owned Album. With the result being I would take this Album anywhere and allow it to be used on any Value of a Cart', the end clean was way beyond all expectations.
Even when US was still lingering as a tool to be used, I thought a US final rinse might benefit a manual clean process, but today that is certainly not thought to be necessary.
The Neil Antin produced process for cleaning as attached is worthwhile being familiarised with, especially the section on the Manual Cleaning Method.
