I have used 'The Last Factory" record cleaning and treatment for products and have found they work as described. I wouldn't be without them.
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?
