Brought home a copy of Pink Floyd's Momentary Lapse of Reason a few days ago from the used record shop. There, the LP looked to be in pretty good shape, but after my usual cleaning in the sink, it still had stains that produced some "pop-corn" effects at various locations on both sides.
I decided that if white vinegar is good for cleaning coffee pots, maybe it would clean my new record. So I put the record on my vinyl cleaning table (that I have to spin by hand), poured some vinegar on and brushed it with my old Ball brand record cleaning brush. I did leave it on for awhile, then rinsed and dried it off. I'm finishing side one now.
Almost zero noise!
I have another Floyd that's going to get the same treatment (Division Bell). Hey, vinegar is cheap.
