I use a Klaudio machine and add three drops of Kodak Photoflo to my water tank. My water is both softened due to where we live and also reverse osmosis filtered.
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.
