Aluminum Foil test for Audio Desk Vinyl Cleaner



I came accross this Aluminum Foil Test in You tube to check the purported cavitation power of ultrasonic cleaners. A positive test should create holes or perforations in the foil after an adequate period of ultrasonic exposure. ((varies from 40 sec to a few minutes))
I tested my Audio Desk Systeme Vinyl Cleaner but failed the aluminum foil test.
How reliable is this test? The other question is how can I check that my cleaner is doing its job (refering to its ultrasonic property) in a more objective way.?

Peterayer,

Some years ago at a CES the folks that imported the Keith Monks machine cleaned my only copy of Tracy Chapmans debut album and ruined it, maybe due to the enzyme cleaning solution or maybe some other reason. So my only experience with the KMRCM was not positive.

Good listening

Benjie, Could you describe the difference in sound between an LP cleaned with the Audio Desk and one cleaned with the Loricraft and AIVS?

I did this comparison only once with a friend's new Audio Desk on one of my LPs. It was cleaned on each machine and I slightly preferred the Loricraft. There was a bit more fine detail and the system seemed to have more overall resolution. And this was when my system was less resolving. Now this was a new LP that had been cleaned once with my PRC 4 and AIVS 4-step plus second final rinse. We listened, then cleaned on the Audio Desk and listened again. Then after my friend left, I cleaned it again on the Lori and it sounded better again.

I realize that this was a quick test and hardly scientific. And I'm not arguing that the Lori is easy to use. It takes me 25 min. per side and it's very boring though I do it next to my computer as I do other things.

I'm just very interested in ability to clean without factoring in convenience and cost for the moment. Once those are factored in, then the discussion changes.

I might take a few of my cleaned LPs over to my friend's house this weekend and listen and then clean them quickly on his Audio Desk and see if we hear a difference on his system.

I do think a slight residue is left by the Audio Desk and an ultra pure water rinse in a second Audio Desk or on a VPI 16.5 would make it sound better, but this is only conjecture on my part. I think Albert Porter has two Audio Desks for this reason. If I can do the test this weekend, I'll report back.
Peter, Why does the Loricraft takes 25 minutes per side? I have doesh several steps and I remember it takingt much less time than this.
