Ultimate approach to have cleanest records could be :
- on used or dirty records first clean with wet vacuum cleaning process or use two ultrasonic cleaners- one for dirty records and second for clean
- use ultrasonic cleaner with suitable liquid ( if you have option use also 80 kHz )
- use second ultrasonic cleaner with just distllled water-optional
- use vacuum cleaner to clean and dry records again with liquid which contains minimal wetting or washing agent

Latest tips: 160928:
After extensive use of ultrasonic cleaners we concluded that specially designed washing additives provided by manufacturers are not good for cleaning records. Records sounded much more noisier and maybe even better, but only after wash with distilled water the noise floor was lowered again. So more testing should be done-but do last rinse with suggested liqud by us.
80kHz- we use Elmasonic P 120H- 37/80 kHz ultrasonic cleaner and we suggest for best performance to use first 37kHz( 15 minutes) and then switch to 80kHz ( 10 minutes). This even further increase transparency and opennes of the sound on LP. Higher is the frequency shorter is the wavelength and betterr are cleaned modulated grooves with higher frequencies as well are smaller particles removed out of grooves.
See suggested list of ultrasonic cleaners. This list will be updated and please check suppliers for correct technical data.
