I use Klaudio's ultrasonic machine and distilled water and that suffices for the vast bulk of my LPs.
Same here. I still have my VPI 16.5 that gets used for really dusty/dirty used records.
Ultrasonic cleaning
How many of you are ultrasonic cleaning your records and what solution are you using? I have a Kirmuss ultrasonic machine and I am currently using Tergikleen solution with distilled water. Have some Audio Intelligence ultrasonic solution on order to try. I can tell a big difference with noisy records lowering the noise floor.
