Actually I use the KLAudio unit, which utilizes only distilled water. The records clean well, sound much better and no harm to the actual lp as no chemicals are involved. Also better for the environment.
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.
