Argh- WINDEX!. Spent most of my audio career in the period when vinyl was king. If there is any commonly available liquid that somebody didn't try to "clean" their records with - I'd be surprised.Almost all of these improvised solutions were a disaster.
If your LP supplier is using windex - find a new source for LP's.Having said that - a lot of old and justifiably famous performances were recorded in the era of non-Dolby A analog tape - these do have noticeable tape hiss in the background. And some are simply recordings that someone loved - played repeatedly and never replaced their needle - they have been ground to pieces. I recently picked up a half dozen London FFrr 's that are even by my standards - unlistenable . The UPS man just dropped off my KAB EV-1 about 10 min. ago - so I will give that a shot - but not expecting much.
