I have had some success recleaning again than using microfiber towel and aquafina water pressing down firmly and spinning many times,then play and reclean with aquafina again.That cleaned up some noisy lp's I gave up on.I manually clean with the towel and water.Sometimes it works.
Why do mint-looking LPs sometimes play poorly?
I've purchased some older Japanese vinyl (e.g., pro-use LPs) and some older half-speed vinyl pressings (e.g., cbs mastersound) and on a few occasions, although they have *looked* perfect under very bright light, they play with quite a bit of surface noise. The LPs are not warped, and the surface noise persists after a thorough cleaning. Any insights or recommendations? Thanks!
