I have no idea where to post this, so I hope this is the right place. Recently I've received many a DVD that has required a cleaning (previously owned, from various sources). I was just going to ask what the best way to clean DVDs is. A whole bunch of DVDs I got are clean, but they have faint swirl marks (like light scratches)...I'd like to be able to clean fingerprints and whatnot off DVDs without creating such marks. Ideas? Thanks.
