this is a rebirth of the objection made by flat earthers in the late 80's when record cleaning machines became popular and record cleaning started to approach today's fetish levels.
Degritter brand ultrasonic record cleaner
I received notification yesterday that the Degritter ultrasonic record cleaner is finally making it into production. I have been watching the company for about a year, as the cleaner has moved from prototype to beta testing , and now to a limited production of the finalized (we’ll see ;-) version. The design is excellent, eliminating my reservations about the high-priced (around $4,000) ultrasonic cleaners, at a little over half their price (just over $2,000, last I read). The Degritter uses 120kHz as it’s ultrasonic frequency, and features water filtering and disc drying. It also looks cool, like a 1950’s toaster! Details available on the companys website.
