I didn't hear or see a difference from handwashing. I think I followed the instructions to the tee. I have a used Led Zep album (Physical Graffiti) that I got from a local friend. It was noisy but looked clean. Washing it made it look slightly cleaner but even though it was bone dry, it made the same crackling noise. It's not static, it's likely damaged. My point though is I don't see how this device is really any more effective than hand washing save for keeping the label dry (though I have yet to have a problem with labels on handwashed LPs so far. What else might I look at? I can't justify spending hundreds of dollars considering I only have about 500 records and most of them are pretty clean and play quietly.
