I've fielded a few questions from folks about how I clean my 78 rpm discs so I thought I would make a video and take you along for the ride. Hope you get something out of it!
@@MrWolfSnack Yes soap. Soap acts as a surfactant in the ultrasonic cleaner which is imperative to the cleaning process. Without it the water could never penetrate into the grooves and the whole thing would be a waste of time.
