Suggestions for CD Lens Cleaner?

I use a CD lenz brush-cleaning disc from Audio Source. Can't say that it improves the sound when no problems are otherwise apparent. But there was one time when the laser lenz must have been dust-contaminated because some discs were skipping a bit, so I used the cleaning disc. That time it fixed the skipping problem, so for about $35 (I think it was) the Audio Source was worthwhile having around. Now I probably run it about 2X a year just as a preventive measure.

Where can you obtain a product like this? Will the products sold for computers also work?

Matrix. I too was worried about damaging my lense so when I read in UHF magazine that they use somthing called "Perfect Image CD lens cleaner", I ordered one for about $30.00 CDN. I was having some skipping once in a while as it had never been cleaned . The skipping went away but could not hear a difference sonicly. I used it my car cd player and kind of bent the little brushes. Being thrifty , read cheap, I did not to fork out another thirty so soon, So next time im my local multi-function drugstore I bought a similar product for about $8.00. They look similar ie. both have tiny little soft brushes ,although in a different layout, but both are made in China. The second one is from by a company called Allsop and calls it self a CD laser lens cleaner. It claims to do CD,DVD and Game players. I can't hear a difference after I use it but I have never had a disk skip since. So like Bob Bundas above I use it once in a while just as maintence. Hope this helps. Cheers steve
