Since I received the ultrasonic vinyl cleaner, I have used it 5-6 times. The results are very satisfactory, to me it's the ideal budgetfriendly option to (deep)clean my vinylrecords collection. It's very easy to use, I set the temperature not higher than 35C, cleaning time between 5-15 minutes according to how dirty the record is. As for the power adapter for the little rotating motor: I don't use the adapter that was included. It makes the motor turn at more than 10 rpm, which to me is way too fast. I took an adjustable power adapter at 6,5VDC output option now with 3 RPM as a result, which is about perfect. The fluid I use is mainly (80%) demineralised water, (20%) isopropyl alcohol and some drops of Tetanal Mirasol 2000 and Agfa Agepon. (these are wetting agents and anti-static water agents to make sure the fluid enters the grooves easily and makes the records anti-static)
