iSonicP4875II+MVR10 Motorized Ultrasonic Vinyl Record Cleaner, 110V (10-Records)

In terms of record cleaning methods and machines, there is no doubt that ultrasonic cleaning is considered the best technology available for getting vinyl records as clean as possible. In terms of the machines on the market, on one end there are the ones costing thousands of dollars, made/marketed by companies dedicated to serving the audiophile community; on the other are the low-cost ultrasonic baths that are designed for general cleaning purposes, to which a universal fitting is attached to hold the records for cleaning. In-between are the machines from iSonic, with performance that is every bit as good as those machines costing thousands of dollars, in a machine that has features and ergonomics you can’t get from a cheaper general-purpose machine.That the iSonic machines resemble a popular “vinyl restoration” machine that costs 3 times as much is no coincidence; iSonic uses the same exact base machine as that “audiophile” model uses. However, here the iSonic improves on that model by allowing you to clean up to 10 records at once (the more expensive brands don’t let you clean more than two 12” records, with most only letting you clean one at a time) which is a huge advantage for anyone that has a lot of dirty records and enjoys hitting the pre-owned record shops/market. The iSonic machine itself is clad in a housing that allows for a very well-designed motor and spindle assembly that holds the records extremely securely and rotates them at a very consistent speed during the cleaning process. Loading and un-loading the records is very easy and quick, and the package comes with high-quality spacers that seal and protect the record label from the water bath. Spacers are also included should you only need to clean a record or two.The quality of the iSonic machine is extremely good. Many lower cost machines use wall-wart power supplies that many doubt could provide the power needed for true ultrasonic cleaning; the iSonic has a robust internal power supply that not only provides enough power to the transducers for true ultrasonic cleaning, but also for degass and water bath heating functions. The unit comes packaged with everything you need to get started, including a very good quality surfactant solution (used to help break surface tension for more effective cleaning), a box of lint-free drying wipes and a drainage hose. I got the machine set-up and running in about 15 minutes. I was able to clean 25 records in the first hour I had my machine running, including an original pressing of The Cure’s “Standing on a Beach” from 1986. That record came out cleaner than it did from the factory…playing it, it was absolutely quiet, without any of the pops and clicks that a record this old should’ve had.In terms of cleaning performance, you really couldn’t ask for more, especially for the price. The iSonic’s transducers pulse at an industry standard 35KHz, which is great for getting down into the grooves of the record and getting the gunk and dirt out of them. Where ultrasonic-only machines like the iSonic will struggle is on records that are extremely dirty and/or have mold. I’m keeping my SpinClean to use as a mechanical pre-treatment step, before using the iSonic to finish the cleaning process. For this reason, I can only give 4-Stars for the Sound Quality rating…there will be some records that using the iSonic just by itself won’t truly get the job done. But 90% of the time, the iSonic will be all you need and the results will be incredible.So, all-in, with the iSonic you are getting all the performance of record cleaning machines costing thousands of dollars, in a unit that allows you to clean more records per session. You also get everything you need to start cleaning your records, in one box…instead of piecing things together with the cheaper, potentially less powerful, units. The iSonic is a great buy, but it performs even better!

I did extensive research into ultrasonic record cleaners after deciding to upgrade from my vacuum record cleaning machine. Review after review listed the Isonic at the top of the heap. Yes it is more expensive than many of the other units, but even looking at the photos made it apparent that it is a much more robust unit.When I unpacked it, it was immediately apparent that it was an extremely well designed and built unit, especially the addons that turn the commercial grade cleaner into a record cleaner. Setup was easy and I had cleaned several LPs, 45s and 78s in just a few hours.I also ordered the extension rod that lets me clean 10 records at a time and since I have an extensive 45 collection, I also ordered the 45 unit. I'm really glad I got the 45 unit because it does such a good job.The results of cleaning has been even better than I expected. The overall impression is that the records are getting a lot cleaner compared to my vacuum RCM. It's like a veil has been lifted from the music, with the highs more detailed and the bass better defined. I had read about similar results, but I was skeptical. I'm now a believer.If you have an extensive collection and crate dig like me, this is a worthy investment. The workflow is much faster than my vaccuum RCM and the results are beyond my expectations!

I bought this primarily to clean my shellac 78 RPM records although I have also used it for my vinyl LP 33 1/3 RPM records. While the description claims it will clean both, for 78s you have to fill the tank to the absolute top so be careful not to jostle the unit or you might leak water into the cabinet. My other complaint is that the spacers provided to protect the record label can actually cover part of the recording on a 78 if it's a longer song (grooves closer to the center hole). With that said, it does do a fantastic job of removing debris. I run my 78s through three 15 minute passes and they come out WAY better. Big difference in the sound quality after cleaning. So if you've got $800+ bucks to spend and a bunch of dirty records, this is the machine for you.

I have been buying new and used records for over 40 years. I stopped buying used classical records about ten years ago because it never failed that when I'd find a Mercury Living Presence in perfect condition I would get home and find out that it sounded like sandpaper. I tried all the solvents and cleaning systems out there but to no avail. An audiophile friend of mine recommended this unit and I trusted his judgment. I am glad I did. I initially cleaned ten albums that were set to go to Goodwill and nine of them came out perfect. One was a solo guitar (Julian Bream) and it was absolutely stunning. To date, about 90 to 95% of all the records I've cleaned have turned out Mint and stunning. I am even cleaning new records before recording them because it makes the silent grooves in between songs SILENT and the quite passages DEAD QUIET. I thought the unit would be a pain to use but I'm finding that I actually enjoy the process. You may want to purchase an additional tub for rinsing. My only complaint is that the screw that is used to secure the shaft that holds the records to the motor on my unit stripped when I went to hand-tighten it. The screw is a M3-0.5 (which is a very small and finely threaded screw). Amazon said that they would have a replacement shaft assembly sent to me but I have yet to receive it. I was able to tap out the hole to a M4-0.7 and this slightly larger screw secured the shaft to the motor spindle. I am not associated with iSonic and don't write many reviews. This product, however, deserved one. Also!!!! My unit has a heater and I have found that if you get the water temp above the low 80s that your albums will warp. It is my understanding that heat does not help or improve the cleaning process. That appears to be true. If you do insist on using the heaters, pay attention to your water temperature. Great product and very well built.
