I have about 35 CEDs that Ive accumulated from ebay and rummage sales. Most of them are in playable condition, but I notice some of them skip pretty bad. I have a new needle on my player so I dont think its a tracking issue. I've physically examined some of my discs that skip worse than others, and they all appear to be in excellent shape with no scratches, but just appear dirty. What is the best way to clean these things? I remember years ago my family had a console record player and we had a velvet pad that we would use some type of solvent to clean the records with. Would I use the same type of product for a CED? Any ideas would be appreciated.
