This guy reviews an ultrasonic cleaner one that costs ~$350 with some before and after data. FYI
Vevor Ultrasonic Vinyl Record Cleaner (review)
Is the Vevor Ultrasonic Vinyl Record Cleaner, so relatively inexpensive, worth it? Does it work? Why did I actually pay for it?www.gadgetguy.com.au
Thanks, I've seen that before. Lots of room for improvement on the after sample, IMHO.
