An ultrasonic record cleaner needs to be a few things… easy to use… does a good job… make records sound as good as possible. I ran a few tests to get to the answers I needed. These tests were just for my personal benefit, but I’ll share the results here.Test #1… MJs Thriller 40th. I have three of these and 2 are still sealed. I cleaned one with a drop of dawn and a couple capfuls of spin clean record cleaner. I added 2 capfuls of isopropyl alcohol for record #2. #3 was an uncleaned sealed copy. I showed no difference between #1 and #2. #3 was veiled with less clarity. This was not ‘night and day’ in difference, but playing these back to back revealed a difference.Test #2- Bjork’s new album. I ordered this on line and had it ultrasonicly cleaned by them and then shipped to me. I bought a second copy from my local record store. I cleaned LP#1 with this cleaner and left LP#2 alone. I assume they used a super expensive ultrasonic cleaner. I got similar results from test #2… this cleaner got the ‘shmootz’ from the pressing off which helps with clarity. It’s nothing crazy, but it is noticeable. It did just as well as the expensive cleaner.Test #3… I cleaned a bunch of my records after my results were shown to be positive and didn’t harm my test records. After I had cleaned a bunch of records, I cleaned some nasty flea market and garage sale finds. I muddied up the water with about 10 disgusting records. These weren’t miraculously saved, but they sounded better and the junk that came off these records was staggering.Final thoughts… I’m happy with my purchase. I don’t need a $4000 machine to clean my records. I will clean all my old records in due time.Snake oil? I don’t think so, but my ‘scientific’ test was bias as I wanted this machine to work. At this price it is worth the investment.
