We all have CDs that don’t quite sound as good as they once did. Could be your player however more often than not it is simply a matter of cleaning the finger prints and other gunk from the surface of the disc. I started using Shine-ola about 6 months ago and am impressed by the results. No, it does not clean up scratches but it does clean up the surface of the disc, something that we are prone to ignore. Shine-ola works on both CDs and DVDs. On CDs, the sound is amazingly better, with DVDs, you won’t believe how it enhances the video. Great Stuff! Bring in a CD or DVD (or both) and we’ll treat it – at no charge.
