Ultrasonic cleaning with kirmuss and loss of high frequency details.

I just purchased the kirmuss US machine and diligently followed their instructions to cycle through minimum 3 cleanings of 5 min each with their surfactant applied each time. Upon testing my favorite vinyl and critically listening through my headphones I am convinced I’ve lost high frequency details. My background is completely silent and ticks and pops have been reduced by 95% or more. So cleaning wise it did the job. Anyone here ever experience loss of high frequency detail after repeated US cleaning? Now I’m worried I permanently damaged my favorite vinyl somehow. Please let me know, thx.

Just wondering if ear protection when using the US cleaner might help?

I simply raised the issue of whether the experienced high frequency loss was actually the record or hearing issues from the U/S cleaning if done without hearing protection. I do not know the answer. I have never used an U/S cleaning machine. I did not mean to take the thread off track.
