The Kirmuss "In the Groove" Ultrasonic Record Cleaner has a good reputation for getting your records cleaner, and in a safer way than other cleaning systems, whether they are vacuum or ultrasonic. As you can see in the photos, this system is set up for 2 X 12" LPs, and one 10" record (vinyl or 78) and one 45 record. You can do them altogether, or one at a time.
This system, and his method requires patience and time - it is NOT a set-it and forget it type of procedure. But if you are willing to follow his instructions, you will have your precious vinyl restored as fully as can possibly be.
I am including all of the accessories that Kirmuss provided when I purchased the machine - and even some extras. I estimate that I have about 4/5's of a full bottle of the Cleaner-Surfactant, and about 1/3 of the anti-static spray. All of these supplies are easy to order. And Mr. Kirmuss is easy to reach, and quite helpful if you have to call him for help.
This sells for $1200 new. I used this machine for two sessions only - it is practically new. My $600 is a reasonable ask. I have the original box, and all User's Manuals.
