I pre-wash with Grove Washer G2, then bathe for 10 to 15 min. in my Ultrasonic cleaner using Reverse Osmosis water. A+
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.
