I use a Degritter ultra Sonic record cleaning machine, and I find it to be very effective with older LPs, and it is very easy to use. I have hundreds of older LPs I "inherited" from various people when folks were discarding their LPs in favor of CDs back in the late 1980s or early 90s so I have considerable experience using the Degritter on old used discs. I find that if an LP is not scratched at all a heavy cleaning with the Degritter usually makes them quite listenable.
Ultrasonic record cleaners
I have a modest lp collection, mixed bag of original college age purchases, used records before the current renewed interest, and some newer albums to replace some older issues from the p mount needle days. Have a vpi 16 machine and audio intelligent form 6 fluid. I’m not finding a significant improvement on my noisier issues. The price of ultrasonic cleaners have come down to a price I would consider. Appreciate the experiences of those who have purchased the ultrasonic machines, are they superior to my vpi and are the less expensive models effective?
TIA
