Here is a very worthwhile solution while you are gathering ideas to get you on your way with confidence.
A US based Used Record Store that supplies a LP having been Ultrasonic Tank cleaned using a machine from the Company KLAUDIO. I have discovered the USM uses side mounted transducers on either side of the LP, and this method of placing the critical parts will have a much improved produced cavitation over a single transducer mounted in the base, as with the most typical tanks found.
I did not discover the Khz for the transducers being used on this machine, but it does state 200 Watts.
I found this outlet and with cleaned vinyl on offer after a short search, I am sure there are others offering a similar service.
It does look like a Anti Static Sleeve, a discipline to keep the fingers of the LP’s surface and a Brush will get you on your way.
If at a certain time of year, the replay starts sounding quite inferior, there may be a static charge present on the LP, there are quite a few ideas on how to decrease the impact of this.
