It's been my experience that US cleaners perform best when cleaning one lp at a time.
Recorded Cleaning Machnies
I'm going to buy a ultra sonic record cleaning machine. I am looking seriously at the Degritter MK2 but I just found the Isonic CS6.1-Pro Record Cleaning System, which has the advantage of cleaning 10 records at a time. Anyone have any experience with either of these? Comments? I have a lot of records (like most folks reading this I suppose) so cleaning 10 records at a time is a big deal. There is a price difference, but frankly, that is not too big a deal given what I am buying here.
