If it did not fail the foil test it would probably ruin your record. Peoples who tried to build their own ultrasonic cleaner using ultrasonic tank have reported high frequency is missing even after one wash using the lowest setting.
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.?
