CD Remove CDs from their case by pressing thumb and third finger on edge of the disc near the top and bottom of the case and pressing on the plastic clasp in the center with the other hand. Since dust is usually held in place by electrostatic attraction, dry wiping on its own does not work effectively. The added friction created by the duster will cause the dust to jump back to the charged surface.
Distilled water is used for cleaning records and CDs for many reasons.
Its precise chemical makeup is known, it will not leave any residue behind, is safe to use, and is inexpensive. Water disperses static charges and counteracts the increase in conductivity from the pick-up of salt deposits from finger prints. However, water alone cannot dissolve grease, thus surfactants are used as additives to enable water to be a grease solvent. Surfactants break grease surface bonds and allow water to penetrate grease solids, causing swelling and then random dispersion. The CCI does not foresee long-term problems associated with the use of nonionic surfactants such as Tergitol.
