I just got an Okki Nokki for Christmas. Since receiving the unit, I clean every record before playing it. I use a homemade cleaner made with distilled water, IPA, Triton X 100 and Kodak Photo Flo. I rinse with distilled water having a little Photo Flo in it as well.
Do you clean your records before play, after play, or once (and then never again)?
All my records have been cleaned at least once, but after play, I'll drop it in my Klaudio ultrasonic cleaner for a quick re-clean. I figure if my stylus is digging / loosening anything in the grooves, it's a good opportunity to get that junk out of there. How about you?
