Nordost Eco 3X

ECO 3X is also very effective for treating Compact Discs. When applied to the label side of a CD you will notice a large improvement in sound quality, as stray electrical charges that build up on the discs are removed. Eliminating this noise at the source results in a much more detailed and musical performance.
ECO 3X should be used when installing new cables and be applied about once every two weeks or more frequently depending upon the environment.
