R U guys serious cleaning records with alcohol or soap???
50% of alcohol will make the grooves flat(forgive me for exhageration but in some way it's true). I do recognise vinyls cleaned with alcohol that have unremovable and visible traces and I bet it means something in terms of sonics.
Why break your head and experiment when you can easy order a professional VPI record cleaning solution $16 a bottle of which you mix with 1/2 galons of distilled water??
